El papel del biocarbono en la sostenibilidad y competitividad de sistemas agropecuarios
Authors: Preston Thomas R
Published: August 2024

Resumen Un gran desafío para los planificadores agrícolas es en el diseño de sistemas agrícolas que combinan la producción de alimentos y la energía con una huella de carbono negativa. El biocarbono promete ser un elemento importante de esta estrategia. El biocarbono es el producto de la carbonización de la biomasa fibrosa en un flujo restringido de aire y a altas temperaturas (de 500 a 1000 °C). Es una mezcla de carbono y ceniza, No contiene nutrientes pero puede aumentar la fertilidad del suelo, incrementando la capacidad de retención de agua y de los nutrientes. Actúa como sitio que facilita la adsorción de nutrientes y micro-organismos del suelo, facilitando la actividad microbiana. Tiene el potencial de ayudar a mitigar el cambio climático, a través de la captura de carbono. Las condiciones de alta temperatura y aire restringido que favorecen la producción de biocarbono se encuentran en que los gasificadores sean estufas ascendentes (TLUD) o reactores de corriente descendente produciendo gas para motores y turbinas o simplemente calor de proceso (como en la fabricación de ladrillos). Así, desde el principio, mediante el uso de residuos fibrosos como materia prima, el sistema de gasificación y la producción asociada de biocarbono, evita el conflicto que se presenta cuando se producen biocombustibles a partir de los recursos naturales de los suelos y el agua en lugar de usar estos recursos como fuente de alimentos (Caja 1). Biocarbono es por  tanto un subproducto del proceso de producción de energía a partir de biomasa no comestible.
La mineria como “locomotora” de la economía colombiana y su costo ambiental
Authors: Villar Argaiz David
Published: August 2024

La preservación de la vida -la riqueza más preciada del planeta - solo se logra preservando sus recursos naturales no renovables. Cuando se afirma que la minería es una de las principales “locomotoras” de la economía Colombiana, o que el país debe “saber explotar sus recursos naturales de manera responsable y sostenible” sólo se están buscando beneficios económicos a corto plazo y su consiguiente conveniencia política, sin considerar las consecuencias generacionales que la minería ocasiona al destruir los ecosistemas. Es más, dado que los recursos minerales son no-renovables, es absurdo hablar de minería como una actividad “sostenible”.

“Yes, We’re Taping”: Mapeando los Inicios del Videoarte en España (1960-1980)
Authors: Panea Jose Luis , Martín Sergio
Published: August 2024

El artículo tiene como objetivo revisar los inicios del videoarte en España acudiendo a los principales catálogos de exposiciones, revistas y monografías publicadas en el período que transcurre entre 1960 y 1980. Estos veinte años son una época hasta ahora poco estudiada en las genealogías del videoarte producido en el contexto europeo y concretamente en el ámbito español. Del mismo modo, la dificultad de acceder a las obras desarrolladas durante estos años, muchas de ellas ya desaparecidas, pone sobre la mesa la “emergencia” de su estudio. Nuestro propósito es, por tanto, contribuir a una línea de investigación que permita localizar estas pioneras experiencias, indagar de una manera más profunda en sus procesos e incluso llegar a posibilitar su recuperación en un futuro. Para ello, adoptamos en la presente investigación un doble enfoque. En primer lugar, cronológico, situando las obras de manera precisa en sus contextos históricos, y en segundo lugar, problemático-conceptual, proponiendo tres recorridos temáticos (precariedad, experimentación y activismos) que engloban los contenidos esbozados por el conjunto de estos trabajos.
PRESENT AND ANCIENT LANDFORMS OF THE MEZHYRYCH GEOARCHEOLOGICAL SITE

Background. Comprehensive geoarchaeological studies of prehistoric and historic human settlements involve analyzing all components of the ancient natural environment, including topography and landforming processes. However, insufficient attention to documenting these crucial characteristics, as well as arbitrary use of geomorphological terms, complicates their further interpretation. The research aims to revise existing geomorphological descriptions and paleogeomorphological reconstructions of the Mezhyrich geoarchaeological site, refining and detailing its position within the modern and ancient land surface structure. Methods. The research was conducted using cartographic methods and decoding materials from aerial photography. Additionally, a thorough bibliographic analysis of scientific publications related to paleogeographical reconstructions of the study area was carried out. Results. Discrepancies have been identified in precisely determining the geomorphological context of this site. The study delves into contentious issues surrounding various approaches to numbering the floodplain terraces. These debates stem from the use of different stratigraphic schemes for Ukraine's Quaternary deposits when dating alluvium. Additionally, the debate extends to criteria for terrace numbering. Through the analysis of satellite imagery, hypsometric and geomorphological diagrams, and other geological-geomorphological materials, the contemporary geomorphological situation has been refined, and the peculiarities of the ancient terrain have been unearthed. The role of morphostructural position, the spectrum of processes, and the dynamics of morpholithogenesis have been pinpointed. Conclusions. The conducted research substantiates the pivotal role of terrain in the selection and organization of safe living spaces for ancient humans. To address the issue of linking the Mezhyrich geoarchaeological site to the terrace level, the proposal is to number the terraces based on morphological features, thereby avoiding divergent interpretations of the ages of correlated deposits and discrepancies in terrace designations. Furthermore, there is potential for utilizing the geomorphological information from the investigated Late Paleolithic settlement as a search criterion for locating other ancient human settlements under similar physiogeographic and geological-structural conditions.
Physical Characteristics Controlling Radiation from Heterogeneous Ruptures—Finite Faults
Authors: Beresnev Igor A.
Published: August 2024

Kinematic simulations of ground motion require representations of the earthquake source: the distribution of final slip, parameters of the source time function, and the velocity of rupture travel. There is a significant ambiguity in prescribing these physical characteristics, causing uncertainty in the resulting motions that needs to be quantified. The representation integral is an appropriate tool: it allows exact calculation of the source effect in both the near and far fields in the frequency band of practical interest. The commonly used distributions of slip have a k-square shape of their wavenumber spectra. Various k-square slips change the slope of the radiated spectra in the range of ∼−2.5 and −4.0 in both the far and near fields. The spectra generated by randomly disturbed constant slip are indistinguishable from those emitted by k-square faults. In both cases, variations in peak values of ground velocity and acceleration between realizations are relatively insignificant: under ∼15% for the same hypocenter position. The slopes of the Fourier spectra produced exclusively by the form of the slip function and the slip heterogeneity are equivalent to using a formal kappa filter with κ ranging from ∼0.025 to 0.045 s. No ad hoc high-frequency filtering (of kappa or fmax type) is required if fault finiteness is accounted for. Geometric irregularity of rupture fronts, at least for the way the front progression is randomized in our case, does not appreciably affect the slopes of the spectra. Its principal effect is in blurring the directivity, reducing the sharpness of radiated pulses. The most influential parameter affecting the peak ground motions for several commonly used slip functions is the maximum velocity of slip: scaling of vmax causes a proportional scaling in peak ground acceleration. This parameter is the most important to constrain to reduce ambiguities in predicted ground motions.

Authors:   Korean Academy Of International Commerce, Inc., Lee Ki-Young , Lee Yang-Kee
Published: August 2024

Purpose: This study analyzes the growth trends of e-Commerce platforms and the direct damage caused to domestic consumers by China's e-Commerce platform offensive, and presents countermeasures to improve the problems.
Research design, data, and methodology: This study analyzes related literature reviews.
Results: Problems caused by the growth of e-Commerce platforms include increased illegal imports, increased consumer damage, increased smuggling and customs evasion, personal information protection issues, and infringement of intellectual property rights, which have increased to a serious level. The increase in illegal imports under the guise of overseas direct purchase and the increase in customs evasion through undervalue are causing serious damage to the national economy and are causing turbulence in the customs clearance order, adversely affecting the sound customs clearance culture.
Conclusions: The government's active efforts are needed to further strengthen penalties under the Customs Act and establish a sound customs clearance order through continuous promotion and information provision. In addition, damage to consumers due to the proliferation of purchasing agents is increasing at a serious level, and improvements to the customs law system are needed to resolve these problems. Lastly, due to the increase in cross-border e-commerce, we must come up with a response plan to protect the personal information of Korean citizens collected by overseas e-commerce platforms and eradicate the import of harmful goods by strengthening the certification system
Weaning off heated humidified high flow nasal cannula successfully in a 24-week extreme low birth weight infant in South-South Nigeria: a case report
Authors: Enato Izehiuwa G. , Uduebor Joseph
Published: August 2024

The use of heated humidified high flow nasal cannula (HHHFNC) has become increasingly popular for providing noninvasive respiratory support for neonates with respiratory distress syndrome (RDS). However, there are several challenges to its use as primary respiratory support in extreme low birth weight (ELBW) preterm infants delivered before 28 weeks gestational age (GA), these include: lack of established guideline; and conflicting reports from studies on the risk of respiratory failure (apnea), necrotizing enterocolitis (NEC), bronchopulmonary dysplasia (BPD) and death. In Nigeria, HHHFNC is not widely known nor used in most neonatal care facilities, including level III Neonatal care facilities. Despite adequate literature search, there is little or no known report or guideline for the successful use of and weaning from HHHFNC in ELBW neonates, delivered before 28 weeks GA in the Country. We present the successful weaning from HHHFNC as primary respiratory support at 30 weeks post conception age (PCA) in an ELBW preterm infant (weighing 700 gm) with severe RDS, delivered at 24 weeks GA in a neonatal care facility in Nigeria. HHHFNC was commenced at 6l/min following surfactant administration and successfully weaned off at 2l/min at 30 weeks PCA, with no incidence of apnea, BPD, NEC, air leaks, nasal septum damage and death. HHHFNC used as noninvasive primary respiratory support for ELBW preterm neonates with severe RDS delivered before 28 weeks GA is effective and safe; in addition, weaning off HHHFNC in this group of infants at 30 weeks PCA should be explored and recommended as a guideline in Nigeria and globally.

Published: August 2024

Neurological emergencies in young patients require prompt recognition and intervention to avert irreversible damage or death. These emergencies encompass acute conditions such as strokes, traumatic brain injuries, status epilepticus, and infections like meningitis. Recent advancements in neuroimaging, including portable MRI, have significantly improved diagnostic capabilities. Management protocols are evolving, with notable progress in treatments such as intravenous thrombolysis and mechanical thrombectomy for acute ischemic stroke. For status epilepticus, the timely administration of antiepileptic drugs is vital. Furthermore, addressing conditions like myasthenic crisis and acute intracranial hypertension involves specific interventions such as plasmapheresis, IV immunoglobulin, and targeted ventilation strategies. Delirium management in hospitalized patients highlights the importance of a multidisciplinary approach, incorporating both pharmacological and non-pharmacological treatments. Education and continuous professional development are essential to keep healthcare providers abreast of the latest diagnostic and therapeutic advancements. This review synthesizes current practices in the assessment and intervention of neurological emergencies, emphasizing the importance of timely, evidence-based management to improve patient outcomes.
‘To be a Player, not a Piece’: LMX-Relationships in Late-career Employment
Authors: Hesselberg Hege Sofie
Published: August 2024

This study employs qualitative interviews with employees (50+) and managers from Norwegian private companies to investigate how retirement age norms affect leader–member exchange (LMX) relationships in the late stages of employment.This research reveals that organizational practices incentivizing early retirement establish retirement age norms and create pressures that significantly impact the LMX dynamic. Employees perceive managers as key in alleviating these pressures. However, the ability of managers to shield employees from retirement pressures varies, as managers face several competing challenges, such as providing opportunities and development for younger employees. While high-quality LMX relationships are crucial in reducing retirement pressures for older employees, differing managerial practices lead to varied support levels within the same organization, putting older employees in precarious positions. The article advocates for policy reforms that limit organizational early retirement practices and promote extended working lives, ensuring a more supportive employment environment for aging workers in private organizations.

Authors: Alqahtani Rashed , Kamhi Alan G.
Published: August 2024

This study examined the feasibility and effectiveness of Remote Learning (RL) for students with learning disabilities (LD) during the COVID-19 pandemic. In the first experiment, perceptions of the appropriateness of using RL to teach students with LD during the pandemic was examined with 99 Saudi special educators. The teachers reported that their students with LD lacked motivation, engagement, and had poor learning outcomes. In the second experiment, IEPs of 33 students with LD were analyzed to compare their learning outcomes before and during the pandemic. The students with LD received fewer teaching sessions, completed fewer IEP goals, and missed more school days during the pandemic than before the pandemic. Taken together, the findings indicated that RL instruction did not meet the needs of students with LD. In the future when considering RL, school districts should provide training and technical support to teachers, IEPs should be implemented consistently, and families should be involved in the intervention process.

Authors: Solonkin Andrey Valerevich , Sukhareva Elena Petrovna , Belikina Anna Vasilievna
Published: August 2024

Background: Safflower is an oil seed crop that can form seeds in extreme conditions, so it can be used as an alternative to sunflower because their growing technologies are similar. Weeds cause significant damage to the safflower crop. The safflower crop does not tolerate chemicals used to control weeds, so the study was devoted to alternative methods of weed control in its crops, namely the effect of seeding rates on weed infestation and seed yield. The goal is optimal seeding rate and its effect on weed infestation of safflower crops. Methods: The experimental site was laid out on the right bank of the Volga River, Kamyshinsky district, Volgograd region, in a dry steppe zone of chestnut soils with a hydrothermal coefficient of 0.6-0.4. Safflower seeds were sown with three seeding rates: 25, 30, 35 kg/ha in triplicate, with row spacing of 15 cm. The experimental results were presented graphically and processed by dispersion analysis. Result: The research results showed that in the area with a sowing rate of 35 kg/ha of viable seeds there was the least weed in the safflower crops, and the seed yield was higher than in other areas with lower sowing rates. Statistical analysis determined that the seeding rate has a 51.1% effect on safflower yield.

Published: August 2024

Background: Bean common mosaic virus (BCMV) which belongs to the genus Potyvirus and the family Potyviridae, causes significant yield losses in legumes across the globe. Traditional methods for BCMV detection and diagnosis, such as visual inspection and serological assays, are often time-consuming, labour-intensive and may lack the sensitivity required for early detection. Advances in molecular techniques have made RT-PCR a powerful tool for the accurate detection of BCMV-infected plants. Methods: Three pairs of specific primers that flank the BCMV coat protein and polyprotein gene were designed using the Primer 3web tool to amplify fragments approximately ranging from 191 to
205 bp. The RT-PCR protocol was then standardized, including the optimization of annealing temperatures for all three primers, followed by the sequencing of the amplified PCR products. The, specificity and sensitivity of primer pair BCMV2 were then established. Result: Three pairs of specific primers were designed and RT-PCR protocol was standardized. The sequenced PCR products showed 98.03% to 99.50 % nucleotide similarity with the corresponding sequences of BCMV isolates used in primer designing. Further, the BCMV2 primer pair specifically amplified the target amplicon (200 bp) from the suspected leaf sample and no amplicon was observed when tested against other pathotypes of potyvirus such as BCMNV, BYMV, CABMV, SMV and PeMoV. The designed primer was sensitive enough to detect 0.05% of target cDNA. Additionally, the RT-PCR protocol was validated using field samples collected from Hyderabad, India. ELISA in combination with RT-PCR using the developed specific BCMV primer pair will ensure a foolproof, sensitive and rapid, procedure for diagnosis of BCMV in the quarantine processing of imported germplasm.

Stueckelberg particle in the uniform electric field, solutions with cylindrical symmetry
Authors: Ivashkevich A. , Sachenok P. , Red'kov V.
Published: August 2024

In the present paper, the system of 11 equations for massive
Stueckelberg particle is studied in presence of the external
uniform electric field. We apply covariant formalism according
to the general tetrad approach by Tetrode-Weyl-Fock-Ivanenko
specified for cylindrical coordinates. After separating
the variables, we derive the system of the first-order differential
equations in partial derivatives with respect to coordinates
(r, z). To resolve this system, we apply the Fedorov-
Gronskiy method, thereby we consider the 11-dimensional
spin operator and find on this base three projective operators,
which permit us to expand the complete wave function
in the sum of three parts. Besides, according to the general
method, dependence of each projective constituent on the
variable r should be determined by only one function. Also, in
accordance with the general method we impose the first-order
constraints which permit us to transform all differential
equations in partial derivatives with respect to coordinates
(r, z) into the system of 11 first-order ordinary differential
equations in the variable z. The last system is solved in terms
of confluent hypergeometric functions. In total, four independent
types of solutions have been constructed, in contrast to
the case of the ordinary spin 1 particle described by Daffin-
Kemmer equation when only three types of solutions are possible.

The Eastern Pontides host a diverse suite of plutonic rocks spanning a wide range of ages and compositions. Among these, the Middle Eocene Kazıkbeli pluton, located in the Kürtün district of Gümüşhane, stands out due to its distinctive petrological characteristics. This study aims to unravel the petrological implications of petrographic and mineral chemical data to constrain the physicaydınçakırochemical conditions (temperature, pressure, oxygen fugacity) under which the Kazıkbeli magma crystallized and was emplaced. By integrating mineral chemical data, we seek to quantify emplacement pressure, crystallization temperature, and oxygen fugacity. A comprehensive understanding of the genetic relationships and physicochemical properties of the Kazıkbeli pluton rocks, as determined through geological, petrographic and mineral chemistry, is crucial for elucidating the geological evolution of the Eastern Pontides. The Kazıkbeli Pluton exhibits a predominant NE-SW orientation and encompasses an area of roughly 46 km². Modal mineralogical analysis reveals a compositional spectrum ranging from gabbroic diorite to monzogranite, with granodiorite and tonalite being the most prominent rock types. Textural variations encompass fine- to medium-grained, porphyritic, poikilitic, and occasionally graphic textures. The primary mineral assemblage of the pluton comprises plagioclase, orthoclase, quartz, amphibole, biotite, and Fe-Ti oxides. Accessory minerals include zircon, apatite, sphene, and allanite. Plagioclases are labradorite to oligoclase (An26 to An66) in composition. K-feldspar minerals exhibited an orthoclase composition (Or80 to Or97). All amphiboles belong to the calcic amphibole field and exhibit a magnesio-hornblende (Mg#=0.63-0.73) composition. Biotites crystallized as solidified melt products with compositions between annite and phlogopite endmembers, plotting close to the magnesium-rich (Mg#=0.52-0.58) end of the phlogopite solid solution series. Calculated crystallization temperatures derived from amphibole and biotite data range from 712°C to 824°C. Pressure estimations calculated using amphibole-plagioclase, amphibole and biotite suggest a range of 0.04 to 2.06 kbar. Oxygen fugacity (ƒO2) values calculated using amphibole and biotite fall between -12.5 and -16.1. Amphibole-based water content estimations indicate a range of 3.7% to 5.7% for the pluton. Biotite compositions within the studied Kazıkbeli pluton rocks exhibit characteristics suggestive of a potential mantle origin. Geobarometric calculations based on mineral chemistry data with geological and petrographic features indicate the emplacement of the Kazıkbeli Pluton at relatively shallow depths within the crust (~1 to 8 km).

Objetivos: Relatar caso de Síndrome de Desmielinização Osmótica (SDO) em paciente internado no Hospital Universitário Walter Cantídio (HUWC). Metodologia: Foi pesquisado na base de dados do aplicativo de gestão para Hospitais Universitários do HUWC paciente internado por SDO durante o período de agosto/2020 à outubro/2020. Após aprovação pelo Comitê de Ética em Pesquisa (CEP) do HUWC, foi realizado o relato do caso com base no prontuário, de forma retrospectiva e descritiva. Resultados: Paciente de 61 anos, portadora de doença renal crônica secundária a glomerulopatia membranosa, em uso de hidroclorotiazida e indapamida, diagnosticada com hiponatremia (sódio 104 mEq) sintomática. Realizada reposição com cloreto de sódio 3%. Apresentou elevação de 04, 15 e 27 mEq/L nas primeiras 24, 48 e 72 horas, respectivamente, resultando em sintomas neurológicos. Neuroimagem evidenciou mielinólise pontina e extrapontina. Após múltiplas intercorrências resultantes de infecções bacterianas, suporte clínico e reabilitação, evoluiu com melhora dos sintomas neurológicos, obtendo alta hospitalar. Conclusões: Faz-se necessário monitoramento do ionograma durante a terapêutica com tiazídicos em pacientes com doenças renais. Este caso demonstra que, mesmo seguindo diretrizes de reposição de sódio, o resultado pode ser imprevisível. Também evidencia a evolução variável da SDO, desde a recuperação dos sintomas até o óbito.
Beyond dopamine: exploring endocannabinoids in Parkinson’s disease

Parkinson’s disease (PD) is a prevalent degenerative movement disorder largely attributed to the dysfunction of dopamine transmission in the basal ganglia. However, the role of the endocannabinoid (eCB) system (ECS) in PD pathology and symptomatology is often overlooked in discussions. Recent research, including our own, has identified multiple homozygous loss-of-function variants in diacylglycerol lipase β (DAGLB), an enzyme involved in the synthesis of 2-arachidonoyl-glycerol (2-AG) - the most abundant eCB in the brain - in individuals with early-onset autosomal recessive Parkinsonism. These genetic findings strongly link eCB deficiency with the etiopathogenesis of PD. Exploring the roles of DAGLB and 2-AG signaling in PD and dopamine transmission could provide a new perspective on PD treatments, focusing on the function of the ECS and the pathophysiological implications of its disruption.

Apis cerana honey bees are members of the order Hymenoptera, Family Apidae, Sub Family Apinae and Genus Apis. A. cerana bees need feed in the form of nectar and flower pollen (pollen). When the dry season occurs, the availability of natural food sources is difficult to obtain, so alternative feed for bees is very important and necessary. This study aims to determine the concentration of sugar solution preferred by A. cerana bees, to determine the distance to the preferred feed source for A. cerana bees and to determine the direction of the preferred feed source for A. cerana bees. The method used in this research is the split-split plot experimental method with the main plot is the direction, the sub plot is the distance, and the sub-plot is the sugar concentration. The sugar concentration used was 0%, 15%, 35%, and 50%. The distances used are 1 m, 4 m and 7 m which are located in 4 cardinal directions from the bee colony. The data obtained were analyzed using descriptive statistical methods, conservative non-parametric Kruskal Wallis (KW) using SPSS software. The results of this study were the concentration of sugar preferred by A. cerana bees, namely the concentration of sugar 50%, the distance of the preferred feed source for A. cerana bees from the beehive, namely a distance of 7 m, and the direction of the preferred source of feed by A. cerana bees from the beehive, namely east direction.
