Elevated Natriuretic Peptides in Patients With Severe or Critical COVID-19: A Meta-Analysis
Authors: Benhuri Benjamin , Aikawa Tadao , Takagi Hisato , Benhuri Daniel , Kuno Toshiki
Published: October 2022

Background

The worldwide COVID-19 pandemic caused by SARS-CoV-2 has resulted in an extraordinary increase in the number of patients who are severely critically ill. For many of these patients, cardiovascular risk factors are key contributors to the development of severe illness. Laboratory markers for cardiac damage and failure, such as natriuretic peptides, are reported to be elevated in patients with severe COVID-19.

Methods

We conducted a systematic review and meta-analysis to compare natriuretic peptide levels in patients with severe COVID-19 vs those with nonsevere COVID-19. PubMed and medRxiv were searched through April 7, 2020. The outcome of interest was the difference in B-type natriuretic peptide (BNP) or N-terminal-proBNP levels in patients with severe vs nonsevere COVID-19.

Results

We identified 9 retrospective cohort studies that had a total of 1,575 patients with COVID-19 who had their natriuretic peptides measured and were classified by disease severity. All studies were conducted in China. Patients with severe COVID-19 had significantly higher BNP levels than patients with nonsevere COVID-19 (mean difference, 69.56 pg/mL; 95% CI, 1.77–137.35 pg/mL; P = .04, I2 = 83%). Similarly, patients with severe COVID-19 had significantly higher N-terminal-proBNP levels than patients with nonsevere COVID-19 (mean difference, 518.65 pg/mL; 95% CI, 152.40–884.90 pg/mL; P = .006, I2 = 86%).

Conclusions

In this study, Chinese patients with severe COVID-19 had higher natriuretic peptide levels than those with nonsevere COVID-19. Studies from all countries affected by the virus will help to further delineate whether the cause is directly or indirectly of cardiac origin and whether preexisting heart failure has an influence on this disparity.

During an energy conversion process, the total harmonic distortion and losses will increase while its power stability decreases. Multilevel inverter technology can be utilized to alleviate the shortcomings of conventional inverters. These technologies have become recognized as cost-effective solutions for a wide range of industrial applica-tions. Reduced component losses and lower switching losses, as well as improved output voltage and current wave-forms are the first advantages of this design. In multilayer inverters, elimination of harmonic components in the inverter output voltage and current is crucial. This paper proposes a system that consists of three different renewable energy sources. Two of them are PV solar systems while the third is wind turbine simulated in MATLAB Simulink. Seven-level inverters based on switch reduction techniques are proposed in this paper. The proposed system design is verified in the absence of PV systems to produce five voltage levels as a contingency in PV systems.
CALCULATION OF ZIP LOAD MODEL COEFFICIENTS IN THE NEARBY PARTS OF THE ELECTRICAL NETWORK USING MEASUREMENT DATA
Authors:   South Ural State University, Chelyabinsk, Dziuba M.A. , Safonov V.I.
Published: October 2022

The article discusses the methodology for recalculating the coefficients of ZIP load model in nodes of electric networks 35–220 kV, according to the experimental data obtained for some another network nodes. The need to recalculate the static load characteristics for nearby parts of the network arises due to problems between networks owners and the insufficient number of certified measuring equipment during the active experiment, as well as the impossibility of connecting the measuring equipment in some places of the electrical network. For recalculation, a model of an electrical network section is formed and standard models of network elements such as transformers, currentlimiting reactors and power lines are used. These models are divided into elementary multipoles and the calculation is performed sequentially for each of them. The given technique is general and allows recalculating the ZIP model coefficients of the load at an arbitrary point of the electrical network according to experimental data at some points of the network.
FAULT LOCATION IN ELECTRIC 35–10–6 kV NETWORKS ACCORDING TO EMPIRICAL CRITERIA IN THE COORDINATES OF THREE SYMMETRIC COMPONENTS

Published: October 2022

The paper investigates the method of detecting fault location in 35–10–6 kV electrical distribution networks based on empirical criteria in the coordinates of three symmetrical components, specific for each type of emer-gency mode. Voltages and currents of the direct, reverse and zero sequence are used in the formulas of the criteria. The formulas themselves were developed according to the following principle: if voltages or currents increase when the fault point moves along the length of the line, they are used as numerators, and if vice versa, the voltages or currents values are used as denominators. For each criterion, a graph of the interpolating function was obtained which is stored in the computer's memory. When a fault occurs, the value of the criterion is calculated and, according to the graph, the place of the emergency mode is found. The calculated mathematical error of the developed method is revealed with a small measurement error of ±0.2 %. It is shown that all errors are less than 1 %, except for single-phase earth fault modes, when the error reaches 2.6 %. As calculations show, the error of the fault location is directly proportional to the resulting measurement error and the accuracy of setting the initial data. So, with a resulting accuracy of ±2.5 %, the maximum error of the fault location is close to 3%, and with an accuracy of ±5 %, it is close to 6 %. Existing fault de-tection devices operate with an error of 3–20 %. Moreover, they are unable to detect damage with ground faults and breaks. The effectiveness of the considered method is confirmed by technical and economic calculations. So, based on one 35, 10 and 6 kV feeder, the economic effect is 200, 150 and 110 thousand rubles per year, respectively, with a payback period of about a year. When applying the method for 1000 feeders, the effect will be about 200, 150 and 110 million ru-bles per annum. Thus, the criteria obtained for fault location are effective from both technical and economic points of view.

Steam compression installations operating from electric energy are widely used in the world for air conditioning. This type of installation has a number of disadvantages, and therefore a new air conditioning installation has been proposed. Ab-sorption heat transformer is an air conditioning and hot water installation based on the principle of an absorption heat pump. The installation can also be used for heating. The installation is able to use renewable energy sources or utilize the heat of exhaust gases as heat sources: for example, from a heating boiler with a temperature of up to 115 °C. The practical significance of the installation lies in resource conservation and environmental friendliness. The use of this installation will ultimately reduce the consumption of primary fuel and reduce the negative impact on the environ-ment. The paper considers the possibility of using a lithium bromide solution in an absorption heat transformer for resi-dential premises. For this purpose, a number of calculations were carried out, according to the calculation method of ab-sorption refrigerating lithium bromide machines. As a result of the calculations, it was established that the use of lithium bromide solution is satisfactory for use in a household heat absorption transformer. However, in order to achieve greater efficiency, the installation scheme requires refinement.

Finally, we derive new necessary and sufficient conditions that ensure uniqueness for the particular case of CRRA Bernoulli utility functions with γ = 3.
Optimal Control for a Tuberculosis Model with Exogenous Reinfection under the Influence of Stigma
Authors: Liguarda Remilou , Caga-anan Randy L. , Bock Wolfgang
Published: October 2022

Often described as the world’s most deadly infectious disease, Tuberculosis remains a serious health threat in many parts of the world, especially in the developing countries. One of the social barriers hindering TB patients to seek and complete medical attention is stigmatization. In this study, we incorporated stigmatization on a model published by Feng et al. last 2000. We obtained the basic reproduction number and showed conditions where multiple endemic equilibrium will exist depending on a reinfection threshold. The model predicted a significant increase in the basic reproduction number as the level of stigmatization increases. We used optimal control theory to investigate the effect of controls to combat stigmatization and compare these controls with the usual controls such as improving treatment and minimizing reinfection. Simulations show that although stigmatization controls are helpful, they are not enough to successfully control the disease. A combination of all the controls will be ideal and some optimal rates of doing it over time are given, depending on the perceived cost of implementation.
Media populism and the life-cycle of the Norwegian Progress Party
Authors: Herkman Juha , Kalsnes Bente
Published: October 2022

The paper examines the media attention given to the Norwegian Progress Party (FrP) during the parliamentary elections in which it participated between 1973 and 2017. Particular attention is paid to the ideas of media populism and the so-called life-cycle model that outlines the relationship between the different media types and a populist movement regarding its life span. Our data consist of media coverage of the parliamentary election campaigns in Norway in Verdens Gang’s (tabloid) and Aftenposten’s (legacy) newspapers between 1973 and 2017 in general (n=16,536) and the FrP’s media attention in these two major newspapers in particular (n=1,671). The research method employed was a quantitative content analysis. The media coverage of the FrP follows somewhat the life-cycle model, but the party’s internal development and status in the political field, immigration as an individual issue, and changes in political and the media environments seem more important factors for the media attention.

Published: October 2022

In this paper, we propose and analyse a mathematical model of the transmission dynamics of cholera incorporating awareness programs to study the impact of socio-media and education on cholera outbreaks. These programs induce behavioural changes in the population, which divide the susceptible class into two subclasses, aware individuals and unaware individuals. We first provide a basic study of the model. We compute the Disease-Free Equilibrium (DFE) and derive the basic reproduction number

R

${\mathcal{R}}_{0}^{0}$

that determines the extinction and the persistence of the disease. We show that there exists a threshold parameter ξ such that when

${\mathcal{R}}_{0}^{0}\le \xi < 1$

, the DFE is globally asymptotically stable, but when

$\xi \le {\mathcal{R}}_{0}^{0}< 1$

${\mathcal{R}}_{0}^{0} > 1$

and in that condition the DFE is unstable. Various cases for awareness proportions are performed using the critical awareness rate in order to measure the effect of awareness programs on the infected individuals over time. The results we obtained show that the higher implementation of strategies combining awareness programs and therapeutic treatments increase the efficacy of control measures. The numerical simulations of the model are used to illustrate analytical results and give more precision on critical values on the controls actions.

Published: October 2022

This paper discusses the complex dynamic behavior of a novel chaotic system, which was firstly established by introducing a memristor into a similar Chen’s system. Then by choosingaas the key parameter, we analyze the stability of memristor system based on eigenvalue theory. It is also found that whenacross some critical values, the system can exhibit Neimark–Sacker bifurcation and chaos behaviors. Some numerical simulations including phase diagrams and maximum Lyapunov exponent graph of the memristor-based systems are presented to verify the existence of chaos attractors. Finally, to make the results of this paper useful in the actual situation, such as the design of chaos security algorithm, analog electronic circuit of memristor chaotic system is designed.
Analysis of concrete beams reinforced by GFRP bars with varying parameters
Authors: Mohammed Shaysh Aziz , Said AbdulMuttailb I.
Published: October 2022

Structural buildings consist of concrete and steel, and these buildings have confronted many challenges from various aggressive environments against the materials manufactured from them. It contains high water levels and buildings whose concrete cover may be damaged and thus lead to the deterioration and corrosion of steel. It was important to have an alternative to steel, such as the glass fiber reinforced polymer (GFRP), which is distinguished by its great effectiveness in resisting corrosion, as well as its strong tensile resistance. Still, one of its drawbacks is that it has a low modulus of elasticity. This research article aims to conduct a numerical study using the nonlinear finite element ABAQUS program on eight beam models with various parameters such as stirrup spacing, compressive strength, reinforcement layer, and type of bar reinforcement under four-point bending. The result shows that the ultimate load capacity of the GFRP beam is higher than that of a beam reinforced with steel and the number and width of cracks are greater in the GFRP-reinforced beam than in the steel-reinforced beam. In general, the serviceability reflected by cracks and deflection is lower in GFRP-reinforced beams than in steel-reinforced beams with higher serviceability. The results, on either hand, showed the expected behavior of GFRP, which is linear elastic to the failure stage. These beams are divided into four groups of beams with different variables studied to understand GFRP bars’ behavior under static loading. The variables taken in this study are the spacing between the stirrups, the compressive strength of concrete, the effect of the number of layers of reinforcement, and the type of reinforcement bar.

Published: October 2022

Tumor-associated macrophages (TAMs) are key contributors to tumor development, accelerated tumor invasion and metastasis, and induction of immunosuppression. Targeted delivery of immunomodulatory agents to promote polarization of TAMs may alleviate the immunosuppressive tumor microenvironment. Calcium carbonate nanoparticles (CCN), which exhibit excellent biocompatibility, pH sensitivity, and easy surface modification, have attracted substantial attention in targeted nano delivery. In this study, CCN were used as a matrix material to develop UNO-peptide-modified lipid CCN for targeted immunomodulation of TAMs by using the mannose receptor overexpressed on the surfaces of TAMs as targets. The preparation of CCN was optimized through single-factor testing with the gas diffusion method with the particle size as the index. The surface modification of CCN with UNO-peptide-modified phospholipids was performed, and its targeting effect on TAMs was investigated. The average particle size of the CCN and UNO-peptide-modified CCN was 144.5 ± 3.8 nm and 167.0 ± 1.3 nm, respectively. UNO-peptide-modified CCN entered TAMs via actively targeted uptake mediated by mannose receptors. Our results demonstrated that the developed UNO-peptide-modified CCN with controlled nano-size and excellent TAMs-targeting properties is a highly promising nanocarrier for targeted delivery of TAM immunomodulatory agents.
Embarking on an adventure of early career academic leadership
Authors: Mitić Tijana
Published: October 2022

Leading a research group as an early career researcher (ECR) in academia presents many challenges. First, it imposes many additional pressures on individuals, causing fear of missing out on a great opportunity that could advance your career. Together, the unsettling nature of short-term or temporary contracts, lack of guidance and the imposter syndrome can trigger a crisis in future leadership. Most leadership positions at universities are held by senior colleagues. ECRs have modest input in decision-making, due to a requirement for specific leadership training and experience with oversight that precedes suitable decision-making. The turbulence of the unprecedented world COVID-19 crisis has been felt disproportionally by many researchers, intensely by those with caring responsibilities. In the current academic climate, navigating either between your postdoctoral or fellowship project, leading others, taking strategic project directions, mentoring or networking may feel like too much. This editorial expresses views on the current state of the matter in academia with suggestions for helpful strategies to employ to meet research endpoints. It also addresses some challenges that new principal investigators and academic leaders may face due to external or institutional change, and provides some tangible advice with action points.
Inteligencia Emocional como Predictor de Satisfacción en Docentes de Infantil y Primaria
Authors: García-Domingo Begoña , Quintanal Díaz José
Published: October 2022

Las crecientes demandas educativas del nuevo milenio han generado un aumento en la cantidad de trabajos centrados en el examen de la satisfacción de los docentes. Nuestro trabajo pretende describir la percepción que tiene una muestra de maestros de la Comunidad Autónoma de Madrid (CAM) acerca de su satisfacción laboral y personal, y explorar la existencia de relaciones entre estos constructos y su Inteligencia Emocional Percibida (IEP) para llegar a poner de manifiesto su potencial papel predictor sobre el bienestar de este colectivo. Los sujetos de la muestra cumplimentaron tres cuestionarios de forma auto administrada tras lo cual, los datos fueron sometidos a análisis descriptivos, correlacionales y de regresión lineal. Los docentes evaluados presentaron un grado de Satisfacción Laboral medio y una Felicidad Subjetiva de “notable alto”. Las correlaciones encontradas entre las tres variables sometidas a medida fueron significativas. Las ecuaciones de regresión obtenidas indicaron que la IEP tiene papel predictor moderado sobre el bienestar laboral y personal del profesorado. Así, su incremento podría suponer una oportunidad de mejora de la calidad del desempeño docente, y elevar el bienestar personal y laboral de los maestros de la CAM, especialmente en aquellos con menor competencia emocional, o con grados de satisfacción reducidos.

Published: October 2022

El presente trabajo busca examinar la percepción de las familias sobre su participación en centros con alta presencia de alumnado inmigrante y escasos recursos económicos. Se examinan las estrategias que facilitan la participación, los obstáculos y las propuestas para impulsarla. La investigación se llevó a cabo en dos escuelas de la provincia de Gipuzkoa mediante 18 entrevistas semiestructuradas y dos grupos de discusión con madres y padres y se analizaron mediante el análisis de contenido. Los resultados muestran que las familias perciben buena relación personal con el profesorado, pero la participación en el centro es baja, sobre todo por parte de las familias inmigrantes. Las familias identificaron estrategias para facilitar la participación (transmisión de información entre madres, existencia de espacios para el diálogo…), obstáculos (insuficiente dominio de la lengua, dificultades económicas, desconocimiento del funcionamiento de los órganos de representación…) y modos de abordar estas y otras dificultades. Se concluye que buena parte de las iniciativas que se llevan a cabo para facilitar la participación dependen de la voluntad de algunas personas y no se encuentran sistematizadas. Escuchar a las familias e incidir conjuntamente en los aspectos que han aflorado en nuestra investigación puede contribuir a incrementar la participación de todo tipo de familias en el centro, y particularmente de aquellas que se encuentran en desventaja; ello implicaría un mayor esfuerzo en comparación con centros con menor diversidad.

Published: October 2022

In the 21st century, international organizations such as the United Nations and UNESCO have been pointing out the education role in the development of competencies to live in line with the sustainability and the objectives of the 2030 Agenda. The pedagogical/curricular practices aligned with a transformative pedagogy that mobilizes the agency power of the students constitute adequate procedures for the sustainability and the development of the objectives of the 2030 Agenda. Through a questionnaire, a study collected data from the pedagogical/curricular practices of 20 teachers from six countries, Denmark, Cyprus, Portugal, Italy, Latvia, and the Republic of North Macedonia, who belong to a European project aiming for sustainability and the development of skills. The analysis of the practices planned and developed by these teachers revealed that critical thinking was one of the most developed skills in the students. Although teachers valued the learning aspects of social issues and the strategies that lead to reflective questioning, the students’ agency power was underestimated. Therefore, considering that these practices were stimulated by belonging to a project, the study showed the need to continue projects that, based on a transformative pedagogy, encourage teachers to value pedagogical/curricular practices that develop the agency power of students.

Authors: Vargas Iturra Yeny Carolina del Pilar
Published: October 2022

El siguiente artículo tiene el propósito de contribuir a la comprensión de las relaciones que se presentan entre las prácticas educativas y conocimientos familiares mapuches y escolares al comenzar la escolarización. Describe un proceso investigativo desarrollado durante un año en escuelas rurales de la región de la Araucanía, en el nivel de educación infantil, con niños mapuches de cuatro a seis años, sus familias y educadoras. Como parte del contexto de desarrollo del estudio se consideró que las familias pertenecieran a comunidades mapuches que mantienen una estructura de transición, es decir han perdido su composición comunitaria tradicional, conformándose como grupos familiares extensos. Metodológicamente la investigación se estructuró como un estudio de caso de alcance etnográfico, que incorporó entrevistas y observación participante. Los resultados precisan aspectos micro y macro sociales que afectan las prácticas educativas tanto en el hogar mapuche como en la escuela. En los casos analizados se observa que la relación entre ambos enfoques epistémicos al iniciarse la escolarización se intensifica, estableciéndose procesos de desajuste, asimilación o resistencia cultural. Estos procesos dependen del tipo de vinculación que establezca el o la docente con la base epistémica mapuche.
La Prevención del Fracaso Escolar en Educación Secundaria desde el Programa de Mejora del Rendimiento y del Aprendizaje
Authors: Márquez Vázquez Carmen , Indarramendi Cintia
Published: October 2022

Con la finalidad de prevenir el fracaso escolar y facilitar la graduación en Educación Secundaria Obligatoria del alumnado con dificultades no atribuibles a su falta de estudio y esfuerzo, la Ley Orgánica de Mejora de la Calidad Educativa aprobó el Programa de Mejora del Aprendizaje y Rendimiento (PMAR). Siete años después de su puesta en marcha, este trabajo tiene como objetivos describir cómo se ha implementado y qué resultados ha obtenido PMAR en centros de Andalucía y Madrid. Primero, se realiza un estudio dedicado al análisis de la normativa que regula el programa en ambas comunidades autónomas. Segundo, se llevan a cabo entrevistas semiestructuradas orientadas a conocer la opinión de nueve responsables educativos de los departamentos de orientación. Los resultados evidencian limitaciones estructurales que afectan al desarrollo del programa en ambas comunidades y regulaciones normativas que explican un trato diferenciado del alumnado en cada territorio. Se pone de manifiesto la baja eficacia de esta medida como estrategia para prevenir el fracaso escolar y se concluye enfatizando la necesidad de repensar en apoyos más tempranos, sostenidos en el tiempo y que faciliten la inclusión del alumnado con dificultades en su grupo de pertenencia.

Published: October 2022

La integración y normalización de la situación educativa de algunas minorías, como el caso del pueblo gitano, sigue siendo un debate que requiere de soluciones adaptadas a la diversidad del actual contexto educativo. Estar oficialmente escolarizados no garantiza unos resultados satisfactorios. En este ámbito, los programas de educación no formal son una herramienta útil de integración y educación en la diversidad, por sus características de flexibilidad y adaptabilidad. Este trabajo evalúa los resultados de un proyecto artístico de formación continua dirigido a niños/as y jóvenes de etnia gitana en riesgo de exclusión social. El proyecto utiliza el bagaje cultural del flamenco, para promover tanto el desarrollo personal de los participantes como su inclusión en el sistema educativo. Para la evaluación de dicho proyecto, se ha utilizado un enfoque metodológico cualitativo, concretamente dinámicas de grupo con técnica proyectivas y cuestionarios abiertos con los agentes implicados. Este proyecto presenta potencialidades para mejorar habilidades artísticas y sociales de este colectivo, así como para potenciar la integración socio-educativa. La inclusión de este proyecto como actividad extracurricular en los colegios públicos con estudiantes de etnia gitana, permite complementar la educación formal para trasformar las realidades educativas segregadoras y enriquecer así la formación de todos los estudiantes educando en la diversidad.

Published: October 2022

El objetivo del presente estudio es evaluar si la aplicación de la punción seca en los puntos gatillo miofasciales latentes se asocia con cambios en el rendimiento de salto. Seis jugadores internacionales de vóley playa sub-21 recibieron tratamiento en el vasto lateral y medial. Se midió la altura de salto SJ y CMJ en cuatro sesiones: antes y después de la intervención (efecto agudo), 48 h y 7 días tras la intervención (efectos a largo plazo). Los jugadores mostraron una pequeña disminución post-intervención seguida de un aumento no significativo a las 48 h. Sin embargo, ambos tipos de salto dieron lugar a un aumento con efecto moderado muy probable tras una semana: 4,13 cm (+10,8%) y 3,54 cm (+8,9%) para SJ y CMJ, respectivamente. A pesar de este aumento significativo, la disminución del rendimiento post-test desalienta su uso inmediatamente antes de una competición.

The development of meteor astronomy in modern Ukraine is considered. The specificity of meteor observation methods requires, first of all, the organization of a network of corresponding observation points. To achieve this goal, it is proposed to combine the scientific and technical capabilities of participating organizations in the form of the Ukrainian Meteor Observation Network (UMON). UMON is a set of two or more permanent observation stations located on the territory of Ukraine, which have the hardware and software for basic and one-sided observations of meteors in different wavelength ranges and conduct such observations. UMON aims to solve important problems of meteor research, structure and evolution of meteor streams and showers, the interaction of meteoroids with the Earth’s atmosphere and their chemical composition. The scientific and technical products of UMON stations are the results of high-precision basic or one-sided observations of meteors in different wavelength ranges, as well as of fundamental and applied scientific and technical research.

OBJECTIVES

A bronchiolitis integrated care pathway (BICP) proved useful in reducing the use of unnecessary medications at a local level. The aim of this study was to reduce overtreatment by scaling up the BICP across our regional health service in the 2019 and 2020 bronchiolitis season.

METHODS

We conducted a quality improvement (QI) initiative in 115 primary care (PC) centers and 7 hospitals in the Basque Country, Spain, from October 2019 to March 2020. The primary outcome measure was the percentage of children prescribed salbutamol comparing the rate to that in the previous bronchiolitis season (October 2018–March 2019). Secondary outcomes were the use of other medications. Balancing measures were hospitalization and unscheduled return rates.

RESULTS

We included 8153 PC visits, 3424 emergency department (ED) attendances, and 663 inpatient care episodes, of which 3817 (46.8%), 1614 (47.1%), and 328 (49.4%) occurred in the postintervention period, respectively. Salbutamol use decreased from 27.1% to 4.7%, 29.5% to 3.0%, and 44.4% to 3.9% (P < .001) in PC centers, Eds, and hospital wards, respectively. In PC, corticosteroid and antibiotic prescribing rates fell from 10.1% to 1.7% and 13.7% to 5.1%, respectively (P < .001). In EDs and hospital wards, epinephrine use rates fell from 14.2% to 4.2% (P < .001) and 30.4% to 19.8% (P = .001), respectively. No variations were noted in balancing measures.

CONCLUSIONS

The scaling up of the BICP was associated with significant decreases in the use of medications in managing bronchiolitis across a regional health service without unintended consequences.

Abstract. The experiment was conducted to assess the use of Abelmoschus esculentus leaves powder as binders in the production of fish feed pellets. Six experimental diets were formulated with three containing starch as binder while the other three contained A. esculentus as binder. Each diet contained maize or wheat individually or in combination as energy source. The diets were designated as MAI (Maize only), WHE (Wheat only), MAW (Maize and Wheat only), MAA (Maize and A. esculentus), WHA (Wheat and A. esculentus) and MWA (Maize, Wheat and Abelmoscus esculentus). Physical properties and dietary effects of the diets were assessed using Oreochromis niloticus fingerlings. There was significant difference (P<0.05) in the sinking rate (cm.sec-1), thickness strength (mm), water absorption index, hardness (mm) and water stability (%) and bulk density (g.cm-3) of experimental diets. Diet MAI (Maize only with corn starch) had a significantly slower sinking rate of 6.77±0.10 cm.sec-1 when compared to the other diets. Diets MAA (Maize only with A. esculentus) and MAW (Maize and Wheat with corn starch) had the highest water stability (88.90±0.46%) while the lowest was diet MAI (85.20±0.10%). Crushing load value for the diet MWA (Maize and wheat with A. esculentus) of 357.00±0.00N was the highest and 119.00±0.00 N for diet MAI was the least. There was significant difference (P<0.05) in the friability of experimental diets at different revolution speed. There were no significant differences (P>0.05) in the mean final weight, mean weight gain, specific growth rate, feed conversion ratio, and feed efficiency of experimental fish fed with the experimental diets. Fish fed diet MAA had a significantly higher (P<0.05) mean weight gain, specific growth rate, feed efficiency ratio compared to the fish fed other diets. The results from this experiment showed that A. esculentus leaf soaked for 24 hours can be used as binder in fish feed production.
Effect of the depth of pre-sowing tillage on the yield of wheat grown by conventional technology
Authors: Hristova G. , Veleva P.
Published: October 2022

Abstract. The present research was conducted to investigate the influence of annual precipitation on the depth of soil
tillage with a disc harrow and to monitor their effect on the productivity of wheat grown by conventional technology. The
study is based on a perennial field experiment on chernozem soils in the land of the Chirpan region located in central
Bulgaria. Annual precipitation data were taken from the local GeoScan Meteo station. Data on the depth of disking,
applied twice or three times during the monitored years according to climatic conditions, were measured with a linear
meter. A moderate correlation (r = 0.568; 0.356; 0.383) between the annual precipitation and the depth of disking during
the three agricultural years was found. Four regression models (Linear, Inverse, Quadratic, and Compound) describing
the relation between them have been developed. From the obtained models‘ coefficients of determination (R2
) for
the three examined years the Quadratic model best expresses the relation between the investigated parameters (R2
= 0.172; 0.216 и 0.186). Statistically significant differences between the average wheat yield in the first and third
agricultural year, as well as between the second and third agricultural year were obtained. It was found (R2
= 0.362)
that the depth of disking affects the productivity of wheat grown by conventional technology about 36.2%.

Abstract. The study was conducted to analyze growth rates and financial profitability of supply chain actors of Large Cardamom based on a sample survey of randomly selected 90 farmers, 10 input suppliers, and 15 traders. Secondary data of area and production were obtained from Ministry of Agriculture and Livestock Development whereas price information was acquired from the Federation of Large Cardamom Entreprenuers of Nepal. The area, production and productivity of Large Cardamom in Ilam district was found in decreasing trend. Market data analysis showed that the price was drastically fluctuating but the compound annual growth rate was significantly increasing by 4.48%. Financial analysis indicated that the enterprise with a project life of 10 years was viable and highly profitable with benefit cost ratio of 3.14, payback period 4.09 years, internal rate of return 81.4%, and net present value of NPR 3.58 million per hectare. Four major supply chain actors were involved. The profit margin was found the highest for the producers (45.68%) followed by regional level traders (28.42%), district level traders (16.36%) and least for the village level traders (9.54%). Traditional driers were still used for curing the capsules with a compromise to the quality of the product. The producers were not found doing value addition activities, whereas tail removing, grading, and packaging were done by regional level traders. Training the farmers on value addition and providing them market information can help to scale up large cardamom production enterprises.
Legacy gambling harms: What are they and how long do they last?

Published: October 2022

Background and aims

Legacy gambling harms are negative consequences of gambling that extend past periods of low risk, moderate risk and problem gambling. Gambling harm is typically measured within a 12-month timeframe and is often restricted to examining harm amongst active gamblers. The present research aimed to explore whether people experienced gambling harms 12 months or more after the resolution of at-risk or problem gambling, and how long these legacy harms lasted.

Methods

An online survey was conducted in New Zealand with past and current gamblers and concerned significant others (CSOs) of gamblers, N = 1,240 (50.8% female), that asked them about both past and current gambling harms.

Results

A majority of both gamblers and CSOs of gamblers indicated that they still suffered from gambling harm even after most of their behavioural issues with gambling had been resolved, 12+ months ago. Legacy gambling harms reduced over time, with harms diminishing most quickly in the early years, and having an average half-life of 4 years. Harms involving community-relationships, church involvement, and domestic and other violence resolved more quickly than others.

Discussion and conclusions

Legacy harms are common among ex-problem gamblers and should be considered in any full accounting of the impacts of gambling.

Conclusion

Understanding the time course and persistence of legacy harms from gambling can provide gamblers, treatment professionals and public health experts with insights into how to address gambling's long-term consequences.
