Authors: Wnęk Jan
Published: February 2023

The article presents some issues related to Henryk Rowids scientific journey to Leipzig in 1913. The purpose of this journey was to participate in a psychological and pedagogical course for teachers and to get acquainted with modern methods of pedagogical work with children in schools. The article presents Rowids comments on the development of research on the child and childhood in Western Europe, and on the rapidly developing scientific literature on experimental child science. The knowledge provided by Rowid was innovative and complemented the current state of knowledge about psychological and pedagogical research conducted in Germany. It inspired further work and studies on child pedagogy. Today, Rowids relation from his scientific journey to Leipzig is an interesting basis to a deeper understanding of the Polish scientific movement in the field of pedology at the beginning of the 20th century. It is also an interesting source of knowledge about the development of the scientific movement among teachers.

Published: February 2023

Non-availability of good quality seeds especially in case of the improved varieties is the major reason for slow adoption of improved forage production technologies. The productivity and availability of quality seeds are vital because the forage crops have been bred for enhanced vegetative potential and as such they are shy seeders with very low seed productivity. The paper discusses the varietal scenario of forage crops in the seed chain, seed quality assurance, seed standards and seed certification. Of the 163 varieties of 11 forage crops notified till 2016, 90 varieties are in the seed chain comprising, 49 cultivars belonging to seven forage crops; guar (5), maize (3), sorghum (19), cowpea (12), teosinte (1), pearl millet (7) and rice bean (2) during the kharif season and 41 of four forage crops, namely, oat (18), berseem (15), lucerne (5) and gobhi sarson (3) during the rabi season. The paper also describes the status of breeder seed production and brings out issues plaguing quality seed production in these crops, assess the future seed requirement and possible approaches to address the daunting task of producing 208.1 tonnes of breeder seed by 2020 from the current level of 78.5 tonnes in the backdrop of lack of effective seed chain and very poor lifting of available breeder seed, as the forage seed production is largely concentrated in the unorganised as well as resource poor sector.

The investigation aimed to study the effect of integrated nutrient management and drought mitigating practices on rainfed chickpea (Cicer arietinum L.) on sandy clay loam soil at Varanasi in winters of 2012-13 and 2013-14. The treatment consisted of combinations of four integrated nutrients levels in main plot and five drought mitigating practices including control in sub-plot. The growth and yield were significantly influenced by different integrated nutrients during both the years. Application of 100% RDF + 2% urea spray proved significantly superior to the 100% RDF + 25% N (VC), 100% RDF + 5 kg Zn/ha and 100% RDF in terms of growth and yield attributes, net returns and B:C ratio. Foliar spray of 2% KCl + 0.4% sodium selenite recorded maximum values of growth and yield of chickpea which was found comparable with 2% KCl during both the years. The maximum net return (Rupees 23 880) and B:C ratio (1.97) was recorded under 2% KCl during both the years. It is concluded that significant improvement in growth characters, yield attributes, yields and nutrients uptake were recorded with the application of 100% RDF + 2% urea spray during both the years of experimentations. Similarly, among the drought mitigating practices, application of 2% KCl + 0.4% Sodium selenite spray was found significantly superior to others during both the years of experiment. 100% RDF + 2% Urea spray resulted in maximum gross return, net return and B:C ratio during both the years of study. Among the drought mitigating practices, application of 2% KCl + 0.4% Sodium selenite spray showed maximum gross return during both the year while maximum net return as well as B:C ratio were associated with 2% KCl spray during both the year of investigation.

An investigation was conducted at organic research farm, Department of Vegetable Science, CCS Haryana Agricultural University, Hisar to study the effect of intercropping and crop geometry in organic production of broccoli (Brassica oleracea var. italica) during winters of 2012-14. Three organic manures (FYM, vermicompost and poultry manure) and two spacings, viz. single row (45×45cm) and paired row (30/60×45cm) were taken in main plot and five intercrops, viz. broccoli (CBH-1), beet leaf (HS-23), coriander (Hisar Bhumit), fenugreek (Hisar Suwarna) and radish (HS-1) including sole crop of broccoli as sub-plot. The trial was replicated thrice. The experimental results revealed that sole crop of broccoli with the application of vermicompost in single row spacing (M2S1C1) recorded minimum days to first and 50% harvesting (56.7), maximum number of leaves (28.4), weight of main head (200.2g), girth of head (15.4cm), number of sprouts/plant (9.8), yield of sprouts/plant (400.9g), yield of sprouts (main head + sprouts)/ plant (601.1g), total yield (296.9 q/ha), plant biomass on fresh (1 661 g) and dry weight basis (149.2 g), of broccoli. While plant height (63.45cm) and yield of intercrops (127.1 q/ha) was recorded maximum with the application of vermicompost in double row spacing (M2S2C5) treatment with radish. Among the intercropped treatments, fenugreek intercropped with broccoli recorded maximum yield (287.7 q/ha) in single row spacing.

Published: February 2023

Indian council of agricultural research introduced a programme in 2006 named Experiential Learning Programme aimed at equipping undergraduates with entrepreneurial skills. Since, its inception factors influencing the utility have not been studied, hence this study is aimed at finding those factors. An explanatory study aimed at finding out among students and teachers which institutional and curriculum related factors have influenced the utility of the programme. The findings revealed that the respondents perceive technical factors to have influenced the utility of programme, while administrative factors were perceived by teachers only. Significant differences and no significant differences were found for perceived factors influencing utility of experiential learning programme by students and teachers, respectively in relation to discipline. The use of most teaching methods was perceived to have been often by students and rare by teachers. Significant differences were noted on perceived utility by students for all the teaching methods except for project method, and for some methods as perceived by teachers. Extra-curricular activities were perceived to have been rarely used by both respondents while significant differences were noted on perceived use of some extra-curricular activities by students. No support provided to graduates who venture into self-employment by institutions. Efforts need to be made to improve on institutional factors in general and include extra-curriculum activities in particular.

Published: February 2023

False flax [Camelina sativa (L.) Crantz.] popularly known as gold-of pleasure, a proposed biofuel species is an oil seed crop of Brassicaceae, family introduced in India in 2009. A study was carried out at Defence Institute of Bio-Energy Research, Field Station- Pithoragarh, Uttarakhand, India during 2011-13 to know the effect of split application of sulphur (20 kg/ha S) on growth, yield and oil content of C. sativa cv Calena (EC-643910). Statistical analysis revealed that split application of sulphur significantly affected parameters undertaken during the study viz. plant height, branch/plant, number of pods/plant, seeds/pod, flowering, pod formation as well as maturity duration, seed yield and oil yield. Camelina productivity enhanced with two split application of S (T 2) and gave 170.84% higher seed yield compared to control. Thus, sulphur applied in two splits resulted in the higher seed yield (1061.13kg/ha), oil content (36.43%) and oil yield of 434.345 lit/ha and is recommended for improving the productivity of Camelina as a emerging biofuel crop.

Published: February 2023

An experiment was conducted during 2014 and 2015 to study the effect of varied extent of girdling for induction of flowering in litchi (Litchi chinensis sonn.) under Bihar condition. Results indicated that circular girdling of 2mm on 50% primary branches produced more flowering panicle, fruit yield, fruit size, TSS, and TSS/acid ratio in Shahi litchi trees compared to ungirdle (control) trees. Findings also revealed that the wound healing duration of girdled portion increases with increasing the size of girdling notch. The average yields from all girdled treatments were about three to five times higher than control. Gradual decrease in fruit weight was noticed with increase of girdling size in both 25% PB and 50% PB. TSS and TSS/ acid ratio showed decreasing trend while acidity and ascorbic acid content of the fruit showed increasing trend with increase in level of girdling width. All girdled shoots showed more accumulation of carbohydrate in leaves than control. Among the girdled branches, gradual increase in leaf carbohydrate and C/N ratio content and decrease in nitrogen content observed with increase in level of girdling but the nitrogen content of bark showed the reverse trend.

Published: February 2023

Gembyung is a traditional art that uses large drums/tambourines as the main tool. Gembyung at the time of the performance displays traditional music and the music that is sung also contains sacred and solemn elements. This is firmly held by the Gembyung players to maintain the authenticity of the traditional arts passed down by their ancestors. Gembyung is a percussion instrument made of leather and wood. Based on the onomatopoeia (word follows sound), the word Gembyung comes from the sound of the percussion pattern gem (beat and hold) and byung (beat and release). At first the Gembyung Subang art developed in the pesantren environment. This Gembyung is usually performed at ceremonies of Islamic religious activities such as the commemoration of the Prophet's Birthday, Rajaban and Activities 1 Syuro which are held around places of worship. In the development of Gembyung, there has also been a change in the form of packaging in the presentation of performances as the goal of research on works of art. The research methodology is qualitative which is oriented towards works of art as a result of packaging products and innovative works, to be applied to performances in general in society.

Iskustva i strategije žena u uličnom beskućništvu u Zagrebu
Authors: Greiner Paula
Published: February 2023

Civilne udruge i osobe koje rade s osobama u beskućništvu često sugeriraju da je beskućništvo kod žena manje često nego kod muškaraca, što potvrđuju i postojeće dostupne statistike. U literaturi je pokazano kako su žene osobito ranjive kad je riječ o beskućništvu, osobito u kontekstu brojnih strukturalnih i društvenih barijera koje pogađaju žene u društvu. Iskustva žena u beskućništvu razlikuju se od iskustava muškaraca te preslikavaju šire rodne nejednakosti. Život na cesti prožet je opasnostima i stalnim izazovima da se zadovolje osnovne potrebe. Korištenje javnih prostora osobito je izazovno za žene u beskućništvu, zbog njihova statusa beskućništva, ali i zbog toga što su žene. Stoga, cilj je rada analizirati žensko iskustvo uličnog beskućništva u Zagrebu, pokazati njegove specifičnosti te identificirati strategije u situacijama različitih oblika isključivanja. U tu svrhu analizirano je deset intervjua provedenih sa šest žena s iskustvom uličnog beskućništva u Zagrebu te terenske bilješke koje su dio širega kvalitativnog istraživanja. U radu se prikazuju iskustva i izazovi života na cesti, koji uključuju osjećaje nesigurnosti i straha, nezadovoljene zdravstvene potrebe, nasilje i seksualno uznemiravanje te isključivanja iz javnih prostora te strategije povezane sa skrivanjem, pronalaskom partnera/grupiranjem i distanciranjem od neželjenih identiteta. Rad ukazuje na važnost prepoznavanja ozbiljnosti i opsega problema beskućništva, osobito ženskoga, te nužnost daljnjeg istraživanja koje uključuje rodne dimenzije i specifičnosti problema.
Social Work and Domestic Violence in Croatia Through a Gendered Lens
Authors: Kujundžić Jana
Published: February 2023

This article examines the gender-blind perception of the social work profession in Croatia and its relation to domestic violence cases. In the past few years, the media and the public have routinely expressed outrage at social workers for not preventing severe cases of violence against women and children. The shift from state socialism to capitalism in Croatian society has considerably affected the profession of social work and facilitated the defunding and understaffing of the welfare sector. I argue that a more nuanced, gendered approach is needed in demanding prevention work from social work centres (SWC). Most studies on the causes of burnout in social workers have ignored the feminisation of the profession and the gendered implication of their precarious professional position and responsibility to protect and help the most vulnerable members of society. The perceptions of social work by other experts working with cases of domestic violence and social workers themselves are important to comprehend a bigger picture of professional judgment and attributions of blame. In-depth interviews were conducted with experts working with domestic violence, including the police, judges, prosecutors, social workers, feminist NGO coordinators, and women’s shelter workers. The feminisation of social work and systemic undervaluing of care work contribute to the easy targeting of social workers while leaving the patriarchal institutionalisation unexplored. For this reason, I conclude that social workers would benefit from class and gender solidary with their clients to fight patriarchal biases.
El régimen de apoyo económico a las energías renovables en España a la luz de Tratado Carta de la Energía: el caso Eiser contra Españ
Authors: Alonso Mas María José
Published: February 2023

El caso Eiser constituye la primera condena a España como consecuencia del nuevo régimen retributivo de las energías renovables. Si bien el laudo tiene en cuenta que, en las circunstancias del caso, las inversiones de los demandantes han quedado sustancialmente desprovistas de rentabilidad y valor, su enseñanza más importante es que el derecho a un trato justo y equitativo comporta la exigencia de una cierta estabilidad regulatoria; de forma que la confianza legítima de los inversores actúa como límite al riesgo regulatorio y no a la inversa, que es como se ha venido concibiendo hasta ahora el riesgo regulatorio por el Tribunal Supremo.
El régimen jurídico del cambio de cultivos para el mejor aprovechamiento de las aguas en la cuenca alta del Guadiana
Authors: Passos Gomes Viviane
Published: February 2023

El presente estudio tiene el objetivo de analizar la evolución del régimen jurídico para el cambio de cultivos para el mejor aprovechamiento de las aguas, dando énfasis a la posibilidad de transformación de un título de derecho privado de aprovechamiento de aguas para el régimen de concesión del uso de aguas en al ámbito de la cuenca alta del Guadiana, dónde todavía existe alguna resistencia de aplicación, en contradicción a lo que ocurre en otras cuencas. Para ello serán resaltados los beneficios tecnológicos, socioeconómicos y ambientales de los cambios de cultivos para la cuenca hidrográfica del Guadiana, las medidas públicas de fomento de la reducción del regadío en esta región y el buen ejemplo de Andalucía. A continuación, será estudiado todo el conjunto normativo sobre el tema, desde de la Ley de Aguas de 1985 y el Texto Refundido de 2001, pasando específicamente por la legislación y planes relativos a la cuenca del Guadiana, la jurisprudencia y la perspectiva constitucional y europea, y los cambios normativos realizados por el RD-Ley 17/2012, la Ley 11/2012 y el nuevo Plan Hidrológico del Guadiana de 2016. Concluyese que si, por un lado, este cambio normativo es muy positivo para el futuro de los regadíos en la cuenca del Guadiana, todavía no es efectivo pues está pendiente de que la Confederación empiece su aplicación.
Más de 90 planes de urbanismo anulados judicialmente por no realizar la evaluación ambiental estrategica (EAE
Authors: Ramos Medrano José Antonio
Published: February 2023

Afortunadamente ya se está generalizando la realización de la evaluación ambiental estratégica a la hora de elaborar los planes de urbanismo, pero ha sido una evolución lenta con muchas dudas iniciales sobre el alcance de esta obligación, proceso en el que los tribunales han jugado un papel importante apostando decididamente por la obligatoriedad de su realización. Una vez conseguido el cambio de evaluar los efectos ambientales “río arriba”, la primera consecuencia es la prevalencia de los aspectos de sostenibilidad a la hora de decidir el modelo de ciudad. Esto va a tener una gran incidencia sobre el esquema tradicional del urbanismo, que tiene que reformular muchos de sus principios tradicionales para dar entrada a las exigencias medioambientales, y entre ellos hay que reformular también el propio plan de ordenación urbana.

In the quest for a sustainable nematode control strategy, alkaloids of physic nut (Jatropha curcas) plant parts were evaluated for their nematicidal control on the root-gall nematode disease of Okra and its mucilaginous property and nutrient composition in 2019 and 2020 cropping season. The experiment was a 3×6 factorial experiments arranged in Completely Randomized Design with five replications in the screen house. Alkaloids extracted from the seeds, leaves and roots of physic nut plants were applied separately at 0, 1, 2, 3, 4 and 5 ml / potted okra plant inoculated with 1,200 infective (J2) larvae of M. incognita. Results showed that 5 ml of Root and Seed Alkaloids application significantly (P=0.05) reduced root-gall nematode infection to a gall index of 1 and 1.2 (rarely galled) when compared to the untreated control  (4 -severely galled) plants thereby achieving more than 100 percent increase in mucilaginous property of okra over the control for both years of study. Moisture content, fat, calcium and sodium also increased more than the untreated control at 5 ml of root and seed alkaloids. Phosphorus and nitrogen contents were on the other hand rather enhanced by the infection. Neither Okra nor root-gall nematode infection affected ash, magnesium and potassium contents of the fruits. Nevertheless, bioactive active constituent of Physicnut plant parts such as root and seed alkaloids can thus be developed as eco-friendly non-synthetic nematicide for improved yield.

There are companies that add a free souvenir to the sale of their products; they contribute to increase the satisfaction of their "heavy users" in their purchases by receiving an extra gift. A very good promotional strategy is to periodically update this souvenir, and generally this strategy is applied according to the results of a market research on the identified tastes of the customers, and then marketing should be used for the design of the gift products. The souvenir suppliers need to have processes that can be adapted to each change requested by their customers, they must have flexible manufacturing. A review of the literature on the promotion of products destined to customers through gifts was conducted, as well as the fundamental aspects to consider in flexible manufacturing for promotional purposes. It was found that it is necessary to have technology for information management that integrates the disciplines of flexible manufacturing, marketing, information technology, design, and costs for souvenir suppliers to effectively meet their commitments; they will have the information in real time; digital information management will involve innovation in the information systems of enterprises: supplier, customer, advertising, and souvenir designer; it will involve business-savvy CIOs; it will also involve digital twin simulation and automation of the production process for effective implementation of flexible manufacturing.

Authors: Ekpechi D. A. , Obiukwu O. O. , Nwufo O. C. , Obasi H. C.
Published: February 2023

Over the years, before the invention of software, some experiments especially direct base experiments had minimum limits to conduct compared to now, due to some possible issues surrounding the process, such as high cost, hazard, and time waste, even some experiments are impossible to run due to complex data involved, which then gave rise to the invention of software that aims in making some of these experiments flexible and safe. This research involved thermal experimentation, mathematical analyses in a MATLAB environment, and data comparison of the experiment and mathematical analysis results of an epoxy-reinforced composite. Five samples were developed (E, S1, S2, S3, and S4) using epoxy reinforced with coconut shell fiber, silicon carbide (SiC), and aluminum oxide (Al2O3) in different proportions and compositions, applying hand-layup and compression molding. Thermal conductivity, diffusivity, degradation, and specific heat capacity tests were conducted using suitable apparatus and ASTM standard methods. The results indicated the minimum thermal properties of polymer material seen in sample ‘E’, due to no reinforced composite. Polymer material in sample E was improved in sample S1, where coconut shell fiber as municipal solid waste was used as reinforcement, possessing satisfactory thermal strength. Natural synthetic fibers (Al2O3 and SiC) used in this research indicated maximum thermal strength seen from samples S2 - S4, due to ceramic properties and close bond microstructural formation of synthetic fibers. 2020 Commercial License Model (CLM) MATLAB software was used to develop mathematical analyses from the experimental data, which when compared, the mathematical analysis results indicated 95% confident bounds on the root mean square error (RMSE) result having the same graphical trend as the experimental result.
ENTREPRENEURIAL EDUCATION: EMERGING EDUCATION 4.0 AND FOURTH INDUSTRIAL REVOLUTION IN NIGERIAN COLLEGES OF EDUCATION
Authors: KOLA AINA, JACOB
Published: February 2023

The review is on Entrepreneurship education, education 4.0, and the fourth industrial revolution (4IR). The paper argued that Nigerian graduates lack creativity and critical thinking skills, contributing to the high unemployment rate among youths. Therefore, the best solution is entrepreneurship education through which students could gain skills for job creation. There is the possibility of entrepreneurial skills in all subjects, particularly science education. However, the paper underscored the relationship between education 4.0, 4IR, and entrepreneurship. Education 4.0 is a response to the needs of the 4IR, where technological progress meets human needs. The crux of 4IR is the advancement in digital technology. The script observed that Nigerian Colleges of Education lack vital digital skills required by Education 4.0 that drives 4IR, a critical challenge to entrepreneurship education. Nigerian Colleges of Education Graduates might soon be out of jobs because work is globally done via machine automation. The paper recommends that teaching and learning in Nigerian Colleges of Education be entirely digital.

Published: February 2023

Annak ellenére, hogy a digitális bölcsészet modern kori gyökerei könnyedén visszavezethetők a második világháború utáni évekig, az oktatásügyi, szakmai folyóiratok (hasonlóan a szélesebb közönségnek szánt sajtótermékekhez) csupán alig több mint egy évtizeddel ezelőtt ismerték fel a területben rejlő potenciált. A túlfűtött várakozásokkal ellentétben a digitális bölcsészet mostanáig sem forradalmasította a humán tudományok kutatási-ismeretszerzési módszereit, bár hatása kétségkívül nem lebecsülendő. Jelen tanulmány az amerikanisztika tudományterületének vonatkozásában vizsgálja a digitális bölcsészet esetlegesen tetten érhető befolyását, górcső alá véve az egyesült államokbeli American Studies Association és a European Association for American Studies folyóiratait és konferenciatémáit. Az összevetés eredményeként kijelenthető, hogy a tengeren túlon a digitális bölcsészet hatása jóval jelentősebb az amerikanisztika berkein belül, ugyanakkor ez a befolyás legfőképpen a feminizmus és a kritikai rasszelmélet területeit érintő cikkek és előadások vonatkozásában érvényesül.
Kreatív természettudományi tehetséggondozás
Authors: Kiss Albert
Published: February 2023

A zalabéri iskolában folyó kreatív természettudományi tehetséggondozás abból a tudománypedagógiai akciókutatásból nőtte ki magát, amely a „Kutatói utánpótlás már tíz éves kortól” (ZSOLNAI:2004:242-248.) című publikációval került a hazai tudományos világ látókörébe Zsolnai József tollából, 2004-ben. Az intézmény 10-14 éves korosztályhoz tartozó tanulói közül azokkal tettem meg a kreatív természettudományi tehetséggondozás kezdeti lépéseit (1997-2000), akik elsősorban a természettudományi tantárgyak iránt érdeklődtek és érzékenyek voltak a természettudományi kutatás módszertani elemeire (megfigyelés, leírás, mérés, kísérlet), valamint a szubjektív alkotásra is. A szubjektív alkotás előzménye nagyrészt a természet tapasztalati megismerése, másrészt a tudomány által már feltárt elméleti ismeretgyűjtés. A tehetséggondozás folyamatában a kreatív tanulók szubjektív alkotásai kezdetben beszámolókban, majd 15-20 oldalas pályamunkákban tárgyiasultak. A pályamunkák sikeres interpretálásához módszertanunkban a kommunikáció dominanciájára törekedtünk. A tanítványok bemutatói (előadásai) már az első általános iskolai tudományos diákköri konferencia országos döntőjén szerepeltek. Legutóbb a kreatív természettudományi tehetséggondozásban részesülő diákok tárgyiasult produktumai a Jubileumi XX. KGYTK országos döntő rendezvényen (versenyen) kerültek bemutatásra. Tanulmányomban a Zsolnai-féle tudománypedagógia értelmezést követően a kreatív természettudományi tehetséggondozás metodikájának nagyléptékű ismertetésére vállalkozom. Majd e metodika alkalmazási eredményéről a Kutató Gyerekek Tudományos Konferenciája című rendezvénysorozat zsűritagjainak (kutató szakemberek) véleményét ismertetem a tudományos utánpótlás-nevelés általános iskolai lehetősége kapcsán. Ezek a kutatási eredmények biztatnak arra, hogy a (nagyléptékben vázolt) kreatív természettudományi tehetséggondozás metodikáját vizionáljam, illetve egy lehetőségként felkínáljam a természettudományi nevelésben érintett elméleti és gyakorlati pedagógusok közt folyó diskurzus bővítéséhez.
Sensitive Temperature Probes Detail Different Turbulence Processes in the Deep Mediterranean
Authors:   NIOZ Royal Netherlands Institute for Sea Research, van Haren Hans
Published: February 2023

In addition to large-scale water flows and eddies, small-scale turbulent mixing distributes heat, water masses, and suspended matter in the deep sea. In contrast to turbulent mixing near the sea surface, which is driven by wind and waves and redistributes solar heat input, large-scale mixing in the deep sea occurs near steep underwater topography such as ridges, seamounts, and continental slopes. For example, above the continental slope in the Western Mediterranean Sea, boundary flows, (sub-)mesoscale eddies, and internal waves dominate water motions. In this area, wintertime dense-water formation, breaking of internal waves, and geothermal heating are associated with turbulent mixing. As a result, vertical stable density stratification is very weak. Detailed observations of turbulent mixing in the deep sea are rare and demand high-resolution instrumentation. This paper provides an overview of various types of deep Mediterranean turbulence observed using high-resolution temperature sensors, including weak turbulence resulting from stable internal waves in late summer and autumn, strong turbulence caused by geothermal heating from below in winter, and moderate turbulence induced by stratified waters pressing down from above during dense-water formation in late winter and spring.

A menudo mueren muchas personas a nivel mundial a causa de enfermedades crónicas como la diabetes, esto se debe a los malos hábitos alimenticios y a una alimentación excesiva con alto contenido de carbohidratos.  Los alimentos funcionales que aportan a una dieta con alto valor nutricional y que contienen compuestos biológicamente activos pueden reducir significativamente los trastornos de ansiedad y enfermedades relacionadas a la hipertensión y diabetes; sin embargo, dichos alimentos tienen muy poca acogida por las personas debido a sus características organolépticas que no son muy gustosas, a esto se le suma los pocos avances científicos he investigaciones. La diabetes mellitus es un trastorno causado por el exceso de azúcar en la sangre, esto se debe a que el organismo no segrega la suficiente insulina para satisfacer su propia demanda. Cabe recalcar que, la fisiopatología es causada por la pérdida de secreción progresiva de insulina o una resistencia por parte de las células β, esto se puede diagnosticar como hiperglucemia que puede desatar en complicaciones crónicas.

Published: February 2023

Los residuos agrícolas se depositan sobre el suelo cumpliendo el sigueiente ciclo: primero descomposición, segunda humificación y por último la mineralización del humus característico de la evolución de la materia orgánica del suelo En los ecosistemas naturales los residuos suelen proceder de la vegetación herbácea, arbustivo, trepadora y arbórea, así como los generados por la fauna. Con referencia al sector textil, la globalización de la moda presenta cambios en el consumo y por ende en las condiciones de producción, transformación, transportes y comercialización, provocando inequidades y exclusión de pequeños productores. mediante este nuevo planteamiento de la reutilización de los residuos orgánicos, se ha brindado una opción diferente para obtener fibras textiles de alta calidad y que cumplan satisfactoriamente los requerimientos que exige la normativa de calidad. Para la protección de los recursos esenciales, existen soluciones que se vinculan con la puesta en marcha de medidas científicas y tecnológicas, cambios de comportamientos, estilos de vida y políticas. Por lo tanto, es muy importante que se tenga alternativas de obtención de fibras que contribuyan en la apmliación de la visión de los artesanos y consumidores. La nueva herramienta para la producción de fibra textil a base de residuos orgánicos es que nos brindaría una reutilización de residuos que normalmente lo desechamos y que a su vez estos residuos provocan un alto porcentaje de contaminación ambiental, si miramos con mayor detalle esta nueva producción nos ayudaría a controlar satisfactoria mente esta problemática que nos da los residuos orgánicos.

La procrastinación académica es el retraso de las actividades, que se da a pesar de conocer las consecuencias en el rendimiento académico y la ansiedad ante exámenes es la preocupación que se da antes, durante y después de una evaluación académica. Esta investigación analizó la procrastinación académica y la ansiedad ante exámenes en estudiantes universitarios (N=433) de las carreras de Enfermería y Nutrición. El modelo de investigación utilizado fue cuantitativo, con un diseño descriptivo y correlacional. Los instrumentos utilizados fueron la “Escala de Procrastinación Académica (EPA)” y la “Escala de ansiedad ante exámenes C-TAS”. Las correlaciones resultaron ser estadísticamente significativas, entre postergación de actividades y ansiedad ante exámenes fue directamente proporcional, mientras que entre autorregulación y ansiedad ante exámenes fue inversamente proporcional.  En procrastinación académica, en las dimensiones de autorregulación y postergación de actividades se encontró una predominancia del nivel promedio. En cuanto a la ansiedad ante exámenes se encontró una prevalencia del 10.2% y las mujeres tuvieron mayor incidencia en comparación con los hombres.

The use of mathematical models is widespread both in simulating the dynamic behavior of vehicle longitudinal motion and in designing related controllers. This paper focuses on control-oriented models for longitudinal motion which better captured the plant dynamics for vehicles with internal combustion engines. Firstly, a review of some simplified models is presented and secondly, two more complex control-oriented models which take into account the powertrain dynamics are proposed.
Numerical solution of algebraic Riccati equations by Newton's method
Authors:   National Institute for Research & Development in Informatics, 8–10 Bd. Mareşal Averescu, Bucharest, Romania, SIMA VASILE
Published: February 2023

Improved Newton solvers, with or without line search, for both continuous- and discrete-time algebraic Riccati equations (AREs) are discussed. The basic theory and conceptual algorithm are briefly presented. Algorithmic details, computational steps, and convergence tests are described. The main results of an extensive performance investigation of the Newton solvers are summarized and compared with those obtained with the widelyused MATLAB solvers, care and dare. Randomly generated systems with orders till 2000, as well as the systems from the large COMPle ib collection of examples, are considered. Significantly improved accuracy, in terms of normalized and relative residuals, and sometimes greater efficiency than for care/dare have been obtained. The results strongly recommend the use of Newton solvers, especially for improving the solutions computed by other solvers.

Published: February 2023

Autism Spectrum Disorders (ASD) are pervasive developmental disorders that cover various aspects of development. Interventions using drugs are still not clearly proven to address the core problems of children with autism spectrum disorders, so interventions are directed at non-pharmacological approaches. The aim of this study is to examine the TEACCH class model for comprehensive interventions for children with ASD in all aspects of development. This research uses a qualitative approach. The data sources for this study were a vice principal and two teachers from one of the autism special schools in Malang, East Java, Indonesia. Data collection techniques through interviews and observation. Data analysis used the Miles & Huberman Flow Analysis Model. The validity of the data was carried out by triangulating sources, techniques, and theories. Research findings (1) The minimal TEACCH class model consists of a whiteboard, bench, visual support, and a sensory/quiet corner. Teachers apply TEACCH by implementing structured learning activities (clear, coherent, and predictable activities) and flexible ones (adjusting to the needs of each child) by involving an independent work system. (2) The application of TEACCH can improve the skills of autistic spectrum children in communication, social, emotional-behavior, and cognitive aspects.
