<p>The use of local resources for food and health care of animals is a highly profitable and sustainable strategy. Among these resources are native trees and shrubs which in addition to providing good quality nutrients, produce secondary metabolites with anthelmintic (AH) effect. Therefore the aim of this study was to evaluate the <em>in vitro</em> AH effect of <em>Gliricidia</em> <em>sepium </em>leaves methanol extract (GSME), through the egg hatch inhibition assay (EHA). Three concentrations of the extracts were tested: 125, 250 and 500 μg/mL. Also a negative control (distilled water) and a positive control (levamisole 2 mg/mL) were included. The GSME showed significant differences <em>P</em>&lt;0.05 when compared with the positive control. The GSME also showed a dose-dependent response in inhibition of eggs hatching. Effectiveness percentages found were: 27.7%, 46.2%, 49.7% of inhibition at 125, 250, and 500 μg/mL respectively. The average dose (ED<sub>50</sub>) obtained through probit analysis was 394.96 μg/mL. These results suggest that the ME of leaves of <em>G.</em> <em>sepium </em>has anthelmintic activity against eggs of gastrointestinal nematodes.</p>

Authors: Kordíková Barbara 
Published: November 2024

Narastajúci dopyt po bilingválnom vzdelávaní na Slovensku si vyžaduje stále viac jazykovo aj odborne pripravených učiteľov prírodovedných predmetov a pregraduálne vzdelávanie cielene nasmerované na daný typ vyučovania. Jedným z efektívnych výchovno-vzdelávacích prístupov, ktorý zastrešuje súhrn metodík prakticky pre všetky formy bilingválneho vzdelávania je prístup CLIL (Content and Language Integrated Learning). Cieľom nášho výskumu je overiť opodstatnenie nového predmetu CLIL – integrované vyučovanie prírodovedného predmetu a jazyka a zistiť či a ako daný predmet prispel k zmene postojov a názorov budúcich učiteľov k cudzojazyčnému vyučovaniu prírodovedných predmetov pred a po jeho absolvovaní v priebehu dvoch semestrov. Náš výskum bol realizovaný intervenčnou výskumnou metódou výskum vývojom (design-based research) spájajúcou kvantitatívne aj kvalitatívne výskumné nástroje, ktoré nám pomohli zozbierať a porovnať dáta od respondentov. Na základe výsledkov výskumu môžeme konštatovať, že predmet CLIL sa stretol u študentov s veľmi pozitívnym ohlasom a priniesol nový pohľad na učenie v rámci ich pregraduálnej prípravy. Absolvovanie daného predmetu viedlo k zníženiu obáv a neistoty študentov v cudzojazyčnom vyučovaní, ale aj k zvýšeniu ich entuziazmu k vyučovaniu vo všeobecnosti. Zozbierané dáta a spätná väzba od študentov nám pomohli naznačiť isté trendy a navrhnúť odporúčania pre skvalitnenie pregraduálneho vzdelávania budúcich učiteľov v snahe lepšie ich pripraviť na aktuálne prebiehajúce zmeny v slovenskom školstve.
La afectación patrimonial de los bancos por las políticas de control de riesgo de crédito por la emergencia sanitaria nacional en el sistema bancario peruano 2020–2022
Authors: Taxa Azabache Jorge Alfredo 
Published: November 2024

El trabajo estudia los efectos de las políticas de control de riesgo de créditos en el patrimonio de los bancos en el período 2020-2022, dichas políticas fueron implementadas en el contexto de la pandemia que vivió el mundo en el año 2020. Se debe recordar que la materialización del riesgo de crédito por falta de capacidad de pago debido a la contracción de las actividades económicas en forma inesperada no tenía ningún antecedente reciente por lo cual las políticas crediticias así como las de clasificación del deudor y exigencia de provisiones no estaban preparadas para un escenario de esta naturaleza. Lo que se encuentra es que las políticas tuvieron el efecto esperado debido a que si bien existió una disminución de ingresos financieros y una menor utilidad, los efectos de la pandemia fueron controlados de tal forma que no hubo una afectación sensible del patrimonio.
Predicting the unseen: A shoreline shift analysis and prediction along Mayo Bay, Davao Oriental
Authors: Masancay Fillmore D , Jimenez Lea A 
Published: November 2024

45%-60% of the world’s population resides in shoreline areas. Shoreline regions are one of the most vulnerable areas to the effects of global warming. Positions of shorelines are challenging to predict, but the trend of accretion and erosion can be determined using statistical and geospatial techniques. Mati City is a major tourist destination for white sand beaches and pristine waters. Shorelines along Mayo Bay are a source of income for the local community. However, Mayo Bay has been subjected to shifts due to erosion. This study aims to determine the trend of the shoreline shift in Mayo Bay from 2013 to 2023. Landsat 8 OLI satellite images are used in this study. Results reveal that most shorelines experienced erosion, with 97.26% erosion transects. The shoreline length has slightly increased by 0.08% from 2013 to 2023 and is predicted to increase by 3.57% in 2063 and 11.51% by 2100. Barangay Lucatan shows the highest shoreline expansion, while Barangays Bobon and Dahican exhibit the most erosion, with mean rates of -27.15 m/year and -23.60 m/year, respectively. With a classification accuracy of 89% and Root Mean Square Error (RMSE) of 0.05, the study provides a reliable basis for Mayo Bay’s shoreline management. The findings will inform erosion mitigation efforts and guide sustainable coastal management plans for at-risk areas.

Authors: Frey Erzsebet 
Published: November 2024

The word herbivore comes from the Latin word herbivora. Herba in latin means “a small plant or herb” and vora means “to eat”. So herbivores are animals that eat only vegetables and/or vegetation. Elephants are herbivorous animals that can consume between 149 and 169 kg (330-375 lb.) of vegetation and ten gallons of water daily.

Authors: Lecaros-Márquez Katherine Patricia 
Published: November 2024

El bullying o acoso escolar es uno de los temas que ha generado mayor análisis en los últimos tiempos dada su importancia en la convivencia en los centros educativos; sin embargo, cuando se indaga sobre la información que revela el impacto del acoso escolar en los estudiantes con Trastorno del Espectro Autista (TEA) se aprecian pocas investigaciones en latinoamérica, destacando fundamentalmente estudios realizados en países del primer mundo, los cuales se enfocan en la reducción de los factores de riesgo que impiden la inclusión de los niños y adolescentes con TEA en el entorno educativo, siendo este de vital importancia para su desarrollo psicosocial. En ese contexto, el presente estudio documental se desarrolla bajo un paradigma simbólico–interpretativo (hermenéutico); a partir de 32 fuentes bibliográficas procedentes de investigaciones sobre el acoso escolar en los niños y adolescentes con TEA, para identificar no sólo las consecuencias de esta problemática, sino también los factores protectores y las acciones concretas que pueden desarrollarse, con el propósito de lograr una mejor calidad de vida para los estudiantes con esta condición.

Published: November 2024

This study seeks to identify learning models that affect students' mathematics learning outcomes. Students at MTs N 4 Bojonegoro have poor or low learning outcomes, especially in Line and Corner material, because the indicators of the learning process at the school have not been optimal. One of the learning models that can be used is the Think Pair Share (TPS) Cooperative Learning model with the Realistic Mathematics Education (RME) Approach. This quantitative experimental research uses Postest only Control Design, with three samples selected using Cluster Random Sampling, two classes as the experimental class and one class as the control class, and using one class, namely class VII E as the test class. The samples have been distributed normally and homogeneously. Data analysis uses anava and post-anava tests. Think Pair Share (TPS) with the Realistic Mathematics Education (RME) Approach produced an average of 76.67, while TPS alone produced an average of 70.81 and the conventional learning model produced an average of 62.42. Students who are taught using the Think Pair Share (TPS) model with the Realistic Mathematics Education (RME) Approach obtained a better average and outperformed students who were taught using the TPS model alone or conventional, as the calculation of this study obtained Fcal > Ftabel with a value of Fα = 10.09 and a value of Ftabel = 3.1.

Published: November 2024

This research studies the application of the nth order Runge-kutta method as a numerical solution to ordinary differential equations. This method was chosen because it is able to provide high accuracy and flexibility in various PDB problems. We implement the nth-order Runge-Kutta algorithm in MATLAB and compare with other numerical methods, such as Euler's method. The results show that the nth order Runge-Kutta method is able to produce more accurate solutions, especially for nonlinear systems. This research makes a significant contribution to the development of numerical solutions for PDB and shows the potential of MATLAB as an effective tool for numerical simulation. Sensitivity analyzes of parameters and time steps were also performed to understand the impact of variations on stability and convergence.

Kommunale etikkomiteer kan ikke bæres av enkeltpersoners engasjement alene
Authors: Karlsen Heidi , Magelssen Morten , Thoresen Lisbeth 
Published: November 2024

Mange ansatte i kommunale helse- og omsorgstjenester som opplever etiske utfordringer i sin arbeidshverdag, mangler arenaer for å diskutere slike problemstillinger. I et prosjekt fikk fire kommuner implementeringsstøtte til å etablere kommunale etikkomiteer, et tverrfaglig forum hvor ansatte, pasienter og pårørende kan få hjelp til å drøfte etisk krevende problemstillinger. I kommunehelsetjenesten er etablering av etikkomiteer å anse som et nybrottsarbeid, som hittil har vært lite systematisk undersøkt. Ved prosjektstart oppnevnte deltakerkommunene to ressurspersoner, og disse ble komiteenes ledere eller sekretærer. I denne studien har vi undersøkt disse ressurspersonenes erfaringer med å koordinere og lede kommunenes etikkarbeid, inkludert å lede konkrete etikkdrøftinger. Data fra tre fokusgrupper, supplert og validert med data fra fem dialogseminarer over tre år, ble analysert ved hjelp av refleksiv tematisk analyse. Funnene viser at refleksjon over etiske spørsmål kan ha betydning utover enkeltstående saker, men også at ressurspersonene fikk omfattende arbeidsoppgaver og ansvar innen implementering, kompetansebygging, markedsføring og forankring. For å unngå å være avhengig av enkeltpersoners innsats, bør komiteenes rammevilkår forbedres.

Published: November 2024

Sorghum is one of the most important cereal crops in the world. It is India’s fifth most produced crop after Rice, Wheat, Maize and Pearl millet by marginal and small farmers in semi-arid regions. It is an important source of feed, fodder and bio-fuel apart from food. Due to importance of the crop, the present study examined its trends in area, production and productivity in Ajmer district as well as Rajasthan state.
Methodology: Study was based on secondary data collected from Directorate of Economics & Statistics, Pant Krishi Bhawan, Govt. of Rajasthan, Jaipur for a period of 20 years i.e. from 2001-02 to 2020-21. The study had performed by using two methodology. First is, to calculate, compound annual growth rates in area, production and productivity of sorghum in Ajmer district and Rajasthan state by testing Linear and semi log and exponential function of growth rate. Second is, decomposition analysis, which was used to calculate the proportional impact of area and yield on the change in overall output for the sorghum crop.
Key Findings of the Study: In case of Ajmer district, exponential function for area and semi-log function for production and productivity was best fitted. For Rajasthan state as a whole, exponential function for area and productivity and for production, semi-log function was best fitted. Results revealed that area, production and productivity were significantly positive at 4.31, 12.29 and 11.96 per cent, respectively for Ajmer district. For Rajasthan state as a whole, it was significantly positive at 0.93, 7.02 and 12.55 per cent, respectively. Results were significant at 1per cent level of significance. Decomposition of these trends further showed that growth in sorghum production in Ajmer was 59.60 per cent due to yield effect, followed by 32.86 per cent interaction of yield and area and 7.53 per cent due to area effect alone, while, in Rajasthan state, growth in sorghum production was mainly due to yield effect i.e. 67.97 per cent followed by interaction effect i.e. 37.15 per cent and area effect i.e. -5.12 per cent.
Conclusion: Decline in area along with enhanced productivity might be a good sign for sorghum production for the state, still efforts should be put forth to bring new high yielding varieties of sorghum to take the full advantage from the crop.

Published: July 2018

AbstractA strategy for the synthesis of quinazolinones via Ru‐catalyzed redox isomerization/acceptorless dehydrogenation was proposed and accomplished. In the presence of a commercially available [(p‐cymene)Cl2]2, a range of desirable products were obtained with o‐aminobenzamides and allylic alcohols as starting materials in moderate to high yields. This strategy is attractive due to high atom efficiency, and minimal consumption of chemicals and energy.magnified image
