Modifying action of metformin on the cytogenetic effects of doxorubicin and cyclophosphamide in mice
Authors: Zhanataev Aliy K. , Kulakova Alla V. , Durnev Andrey D.
Published: May 2023

BACKGROUND: The causal relationship between mutagenesis and carcinogenesis is well known. Hence the wide interest in the study of the mutagen-modifying effects of natural and synthetic compounds. Particular attention is drawn to widespread compounds. One of them, metformin, is widely used as a hypoglycemic drug.
AIM: evaluation of the influence of metformin on the cytogenetic effects of doxorubicin and cyclophosphamide in mouse bone marrow cells.
MATERIALS AND METHODS: Male F1 CBAxC57Bl/6 hybrid mice were used. Cyclophosphamide (20 mg/kg) or doxorubicin (10 mg/kg) was administered intraperitoneally, metformin was given orally once or for 4 consecutive days. The latter administration of metformin was combined with mutagen administration. Cytogenetic preparations of bone marrow cells were prepared 18 hours after metformin administration and 24 hours after its combined administration with mutagens. Chromosomal aberrations were analyzed according to accepted protocols.
RESULTS: Metformin per se showed no cytogenetic activity at doses of 500, 1000, and 2000 mg/kg. At a dose of 500 mg/kg, but not 100 or 250 mg/kg, metformin reduced the cytogenetic effects of doxorubicin. Metformin administered once and for 4 days at doses of 100, 250, and 500 mg/kg or once at doses of 10 and 20 mg/kg increased the number of metaphases with chromosome aberrations induced by cyclophosphamide by a factor of 2 to 3. At doses of 2.5 and 5 mg/kg, metformin had no modifying effect on the mutagen effect.
CONCLUSION: Metformin attenuates the cytogenetic effects of doxorubicin and enhances the cytogenetic activity of cyclophosphamide in mouse bone marrow cells. This allows us to conclude that metformin has mutagen-modifying properties.
Progress in the reliable detection of near-surface reflectors when inspecting anisotropic and isotropic material using the total focusing method
Authors: Bergbreiter L , Grager J-C , Narr A , Mooshofer H , Grosse C U
Published: May 2023

Load-bearing components made of composite laminates of several centimetres in thickness, for example those used in wind turbine blades, are frequently used in the energy sector. These components are usually tested using conventional ultrasound techniques. A typical approach to increase
the energy penetration depth is testing with lower frequencies. This leads to a decrease in sensitivity and consequently to reduced detectability of small defects compared to higher frequencies, especially for defects close to the surface. Another possibility is to use high excitation voltage
or gain to improve penetration, but this also leads to a much more pronounced initial pulse with saturated or clipped A-scans, resulting in a loss of information. Consequently, the defects close to the surface are often indistinguishable to the initial pulse and are not detected. In comparison
to conventional ultrasonic testing, the total focusing method (TFM) shows higher resolution of near-surface defects using the same frequencies. The TFM can be adapted to anisotropic media by consideration of the direction-dependent wave propagation. Therefore, sound paths not perpendicular
to the surface, which show less clipping, can be used for imaging. In this paper, approaches for improving the detectability of defects close to the surface in carbon fibre-reinforced plastic (CFRP) and aluminium using full matrix capture (FMC) and the TFM are discussed. As a result, defects
in CFRP with a depth of 0.9 mm and above can be detected. The presented methods also improve the signal-to-noise ratio (SNR) of near-surface defects in the TFM reconstructions up to 4 dB. The first approach filters the FMC pulses in the wavenumber-frequency domain, which reduces the aforementioned
disturbances in the time-domain signals and thus improves the detectability of near-surface defects. The second approach is based on a maximum angle in the reconstruction step, which reduces the entries of the information matrix based on location. This procedure is similar to taking the directivity
function of each array element into account. Therefore, only time signals with a high signal-to-noise ratio are considered.
Automatic classification of weld defects from ultrasonic signals using WPEE-KPCA feature extraction and an ABC-SVM approach

Published: May 2023

The classification of weld defects is very important for the safety assessment of welded structures and feature extraction of ultrasonic defect signals is vital for defect classification. A novel approach based on wavelet packet energy entropy (WPEE) and kernel principal component analysis
(KPCA) feature extraction and an artificial bee colony optimisation support vector machine (ABC-SVM) classifier is proposed in this paper. Firstly, the WPEE method is adopted to extract ultrasonic signal features of weld defects and KPCA is used for feature selection. Secondly, an ABC-SVM
classifier is employed to perform defect classification. Finally, experiments involving defect feature extraction, selection and classification are carried out using four types of weld defect. The results demonstrate that the performance of the proposed feature extraction method based on WPEE
is superior to that of wavelet packet energy (WPE). In addition, the WPEE-KPCA method achieved a higher accuracy rate of defect classification than WPEE.
Study and application on the early damage signal characteristics of ultra-low-speed and heavy-load rolling bearings of large amusement machinery
Authors: Liu Yuan , Jin Yaguang , Cui Gaoyu , Shen Gongtian
Published: May 2023

Ultra-low-speed and heavy-load bearings are widely used in large amusement machinery. Their breakdown results in great economic losses and possibly even personal injuries. Using their damage signal characteristics to quickly identify early damage is an effective means of preventing
accidents. In this study, to determine the early damage signal characteristics of the ultra-low-speed and heavy-load slewing mechanism, a typical ultra-low-speed and heavy-load bearing rotation experimental platform and signal testing system are designed and built, so as to simulate the operation
of the rolling bearings of large amusement machinery with ultra-low speed and heavy load. Next, by constructing different bearing damage sizes and operating conditions, the vibration signal characteristics of different degrees of crack damage are analysed, along with the signal variation law
of the same damage under different operating conditions. The effectiveness and practicability of this method are verified through the application analysis of a slewing bearing of a typical piece of large amusement machinery. The results of this study provide a reference for quickly identifying
early damage in similar equipment and determining the damage state.

Published: May 2023

Background: Obstetricians and paediatricians are concerned about multiple pregnancy because of its high association with maternal and perinatal morbidity and mortality. This study aims to determine the obstetric and perinatal outcome of multiple pregnancy at a teaching hospital in Southern India.
Methods: This retrospective study was conducted in the department of obstetrics and gynecology, Basaweshwar teaching and general hospital, and Sangmeshwar teaching and general hospital, attached to Mahadevappa Rampure medical college, Kalaburagi from August 2020 to August 2022. The analysis included data on 36 women between 20 and 35 years of age, with ≥ 24 completed weeks gestation, having multiple pregnancy during the study period after applying the exclusion criteria. The data was retrieved from the hospital medical records that included demographic details, complications of pregnancy, and maternal and neonatal outcomes. The data was expressed as frequencies, percentages, mean and standard deviation. Statistical data was analyzed using SPSS 20.0 software. Qualitative data of the maternal problems during intrapartum and postpartum period was done using the test of proportion and chi-square test was applied for significance. Quantitative data was analyzed by t test considering a p value less than 0.05 as statistically significant.
Results: There were a total of 36 women with multiple pregnancy with the overall incidence of 12.5 per 1,000 births (1.25%) during the study period. Preterm labour complicated 27.7% of multiple pregnancies, 13.8% of the multiple pregnancies were complicated by severe preeclampsia, 11.1% were complicated by imminent preeclampsia, 8.3% had intrauterine death in 1 of the twins, and 2.7% had oligohydramnios. 33.3% had iron deficiency anaemia, 22.2% had gestational hypertension, and 13.8% had hypothyroidism. There was no maternal morbidity. Majority (55%) were delivered by LSCS, whereas 44.4% were delivered vaginally. Postpartum haemorrhage complicated 5.5% of twin deliveries. The total fetal loss was 2.4%. There was no maternal mortality in our study.
Conclusions: There is higher incidence of adverse maternal and perinatal outcomes among multiple pregnancies than singleton pregnancies. This mandates adequate counselling about risks and required monitoring to avoid adverse outcomes.

Исследование внутренних напряжений при пьезотермообработке пластика
Authors: Цой Ю.И. , Блинов А.К.
Published: May 2023

Процесс отверждения адгезива представляет собой реакцию поликонденсации или сополимеризации, сопровождается образованием трехмерного пространственного полимера,его уплотнением и уменьшением объема. Величина образующихся внутренних напряжений будет зависеть от величины усадки адгезива и прочностных характеристик клеевого соединения. Авторами были определены экспериментально величины внутренних напряжений некоторых адгезивов. Как известно, карбамидоформальдегидные клеи содержат большое количество реакционноспособных метилольных групп, которые в результате реакции поликонденсации с ОН- группами, образуют трехмерный пространственный полимер, отличающийся большим количеством поперечных сшивок, которые влияют на жесткость, усадку полимера, что и подтверждается большой величиной внутренних напряжений (2,2МПа). В отличие от карбамидоформальдегидных клеев полиэфирные смолы в процессе отверждения под действием инициатора и ускорителя вступают в реакцию сополимеризации с различными мономерными соединениями, образуя небольшое количество поперечных мостиков. Поэтому пленки из полиэфирных смол отличаются эластичностью, малой усадкой, что и нашло свое отражение в небольшом значении вычисленных внутренних напряжений (0,35 МПа ). Что касается карбамидоалкидного клея, то наличие в таком клее алкидной смолы, модифицированной растительными маслами, повышает эластичность клея (1,5МПа) по сравнению с чисто карбамидоформальдегидным клеем. В качестве эпоксидного адгезива нами был исследован эпоксидный клей в смеси с карбамидоалкидным клеем. Как видно, такой клей тоже обладает неплохой эластичностью (0,95МПа). Изучена также кинетика изменения внутренних напряжений при пьезотермообработке стеклопластика и декоративного пластика в зависимости от продолжительности охлаждения и скорости охлаждения. Полученные данные могут быть полезны инженерно-техническим работникам, занятых в производстве слоистых материалов.

SORPTION OF APOLAR LIQUIDS BY NATURAL HIGH MOLECULAR COMPOUNDS
Authors: Tymchuk A. F. , Streltsova O. O. , Purich A. D.
Published: May 2023

The modern technologies of the adsorption processes are searching of the new, ecologically friendly adsorbents as natural polymers – chitin and chitosan. Chitin and chitosan adsorbents have high adsorption ability in relation to mineral oils, dyes, alcohols, phenols and heavy metals. The basic natural sources of chitin are the shells of crustacean and the biomass of fungus` mycelium. Chitin provides the mechanical strength of the structure without rigid bonds between microfibrilles, that allows to keep the certain elasticity of a cellular wall.
The submitted researches are devoted to studying adsorption activity of chitosan and chitin received from the shells of crustacean in relation to of organic polutants.
It was shown that the use of chitin and chitosan polymers of natural origin as sorbents is a worthy alternative to synthetic sorbents. Natural sorbents have advantages due to environmental friendliness, safety and biodegradability. It has been experimentally proven that the investigated natural polymers absorb organic pollutants with an efficiency of up to 98%. The nature of the polymer and the method of its introduction affect the effectiveness of the sorption process. Sorption can be described using the Langmuir and Freundlich sorption equations.
In order to clarify the sorption mechanism, the temperature dependence of the process was studied. In all cases, the sorption of vaseline oil decreases with increasing temperature, which suggests a physical mechanism of sorption. Sorption occurs due to dispersion interaction. Hydrophobic interactions between molecules of organic substances and non-polar regions of chitosan macromolecules make a certain contribution to the mechanism of sorption of the studied substances.
The effective sorption capacity of chitosan is explained not only by its physical and chemical properties, the developed structure of micropores, but also by the method of adding the sorbent. Apolar liquids are sorbed due to hydrophobic interaction, chitosan forms hydrogen bonds that can bind polar components in the composition. The high sorption activity of chitosan in relation to organic pollutants, surface-active substances, heavy metals, dyes, its renewability and ability to biological decomposition allow it to be considered a sufficiently effective and practically universal sorbent.

Published: May 2023

With the COVID-19 pandemic caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), many areas in the world witnessed an increase in fungal infections and the corresponding increase in mortality. In our study, we attempted to identify common fungal pathogens encountered in patients with COVID-19 and to find microbiological and histopathological parameters that may help diagnose these etiological agents. The clinical manifestations, demography, and disease outcomes in patients with fungal infections associated with COVID-19 were also studied.

The observational cross-sectional study was performed at the Government Medical College and District Hospital, Palakkad, India. We used case records and laboratory records of patients admitted with COVID-19 and diagnosed with a fungal infection, as well as records of post-COVID-19 patients with fungal infection. The study period covered six months from March to August 2021. The study included 50 patients aged 40-74 years (median: 56 years).

We found that mucormycosis and aspergillosis are important invasive fungal infections that prevail in COVID-19 patients. The most common risk factors associated with these fungal infections include diabetes mellitus and treatment with corticosteroids. KOH (potassium hydroxide) mount test and histopathological examination are very useful methods for etiological diagnostics. The overall mortality rate in the observed patients was 71.4% (85.7% for mucormycosis and 57.1% for aspergillosis). Thus, invasive fungal infections in COVID-19 patients with co-morbidities are associated with a high mortality rate.
International entrepreneurship and global mindset: a theoretical discussion
Authors: Silva Spindola Correia Adriana Mirelly , Pereira Yákara Vasconcelos
Published: May 2023

Objective: The purpose of this study was to analyze the relationship between the constructs of international entrepreneurship (IE) and global mindset (GM). Method: A bibliographic investigation was conducted in the journals of the Coordination for the Improvement of Higher Education Personnel (CAPES), Emerald Insight, Scopus, Spell, Springer and Web of Science. Descriptors (English and Portuguese) were used in the databases to search for scientific articles that related to the themes of IE and GM. Main Results: Convergences and divergences between the IE and GM constructs and contemporary trends were perceived. Regarding convergences, two important aspects were present in this discussion: the entrepreneur's behavior and its influence on the internationalization process. Entrepreneurial skills, international knowledge, and global orientation stand out in entrepreneurial behavior. In the internationalization process, the speed of internationalization is emphasized as part of the process. Regarding the differentiating characteristics between the IE and GM constructs, cosmopolitanism is present in the first and a combination of individual global mindset (IGM) and corporate global mindset (CGM) is present in the second. Relevance / Originality: This is a theme little discussed in the literature. This study highlights the influence of GM, its relationship with IE, and the factors that can jointly impact international networks. Theoretical / Methodological Contributions: This research clarifies that, although the GM can be expressed independently of EI, the performance of IE is related to the presence of GM.
Con gratitud. A Salomón el sabio
Authors: Giusti Miguel
Published: May 2023

Cuando llegó a mis manos por primera vez, hace ya muchos años, la obra de teatro Natán el Sabio, de Gotthold Ephraim Lessing, me quedé muy impresionado por el hondo mensaje humanitario y por la fuerza dramática de aquella estupenda obra, pero tuve al mismo tiempo la sensación de que el personaje central, el judío Natán, era una figura tan admirable que parecía poco verosímil. Como se recordará, Natán es presentado en la obra como una persona que reúne cualidades muy valiosas, pero también muy disímiles entre sí: es un hombre cultivado, a la vez que un comerciante exitoso; un defensor de causas humanitarias y un político diestro en negociaciones complejas; una personalidad de gran prestigio y reconocimiento en toda la región, no solo entre los suyos, al mismo tiempo que un hombre bondadoso, capaz de gestos conmovedores de solidaridad con las personas más humildes. De él dice Saladino que «su Dios lo ha bendecido con los más grandes y los más pequeños beneficios: el más pequeño, la riqueza; el más grande, la sabiduría» (Lessing, 2010, p. 86). Pese a su sencillez, o quizás gracias a ella, Natán ejerce un extraordinario magnetismo entre quienes tratan con él e irradia sabiduría y bondad en muy diversas formas. Para describir a una persona así —se me ocurrió entonces—, fue seguramente indispensable para Lessing recurrir a una obra de teatro: solo con la ayuda de recursos dramáticos, con la posibilidad de presentar escenas o episodios vitales en los que fueran apareciendo sucesivamente las múltiples virtudes del protagonista, parecía posible componer un retrato coherente y armónico de su asombroso carácter.
Amor y diálogo o el ámbito del pensamiento. Aspectos de la dialéctica de forma y contenido en la tradición occidental
Authors: Vila-Chã João
Published: May 2023

Mi intención, en este ensayo, es analizar la relevancia de la forma de expresión dialógica en el contexto de la tradición del pensamiento occidental. Como forma literaria, el diálogo tiene sus orígenes en Grecia durante el siglo V a. C., habiendo florecido de manera particular durante el siglo que vio la aparición de los escritos filosóficos de autores tales como Jenofonte, Platón e incluso Aristóteles. Etimológicamente, la palabra dialogos se refiere a una discusión investigativa, distinta de una simple conversación, o logos. En la Edad Media, sin embargo, popularmente se llegó a considerar el diálogo como limitado a solo dos personas.
Las comisiones de la verdad y la jurisprudencia de la Corte Interamericana de Derechos Humanos. ¿Hacia la parajudicialización de las comisiones de la verdad?
Authors: Salmón Elizabeth
Published: May 2023

Un efecto poco estudiado del trabajo de las comisiones de la verdad es su interrelación con las instituciones del derecho internacional de los derechos humanos (DIDH en adelante), como la Corte Interamericana de Derechos Humanos (Corte Interamericana o Corte IDH en adelante), la cual ha hecho un uso profuso de sus informes finales. Sea porque su utilización por parte de este tribunal regional es más bien reciente en el tiempo o porque se trata de una consecuencia no prevista de este mecanismo de justicia transicional y, por tanto, no convoca a los especialistas en la materia, lo cierto es que el uso de los informes de las comisiones de la verdad en sede jurisdiccional plantea una serie de retos jurídicos e incluso políticos poco analizados.

En 1983, un grupo de mujeres quechuas en Ayacucho decidió organizarse para reclamar al Estado por el paradero de sus familiares, los cuales habían sido detenidos y luego desaparecidos. Crearon, así, la Asociación Nacional de Familiares de Secuestrados, Detenidos y Desaparecidos del Perú (ANFASEP). De eso hace ya más de 30 años. Ellas siguen organizadas hasta el día de hoy luchando por lo mismo.
Buscando/construyendo el sentido a la Independencia
Authors: López Soria José Ignacio
Published: May 2023

Lo que presentamos a continuación forma parte de un trabajo mayor de carácter histórico-filosófico. Aquí, nos fijaremos en el aspecto discursivo, es decir, en la dimensión de provisión de sentido al proceso de la independización. Lo avanzado en el estudio de esta variable y otras de este proceso me permite suponer —recuérdese que estamos en el momento de la formulación de la hipótesis—, primero, que los afanes de los independizadores se concentraron en la puesta en escena de un gobierno republicano («la política») más que en la puesta en forma de una sociedad democrática («lo político»), y, segundo, que el discurso fue tan pobre que no logró dar sentido al todo social (proveerle de marcadores temporales y contingentes de certeza) y, por tanto, no consiguió la articulación transitoria entre el gobierno y la sociedad. Quedó, así, instalada en el Perú una contradicción —más aguda de lo que ocurre en otras sociedades— entre «la política» (puesta en escena de un gobierno republicano independiente) y «lo político» (puesta en forma de una sociedad democrática), lo que de alguna manera explica la dificultad para elaborar un discurso provisor de sentido a esa supuesta totalidad.
¿Existe en Colombia una política institucional que reconozca la memoria de las víctimas del conflicto?
Authors: de Gamboa Camila
Published: May 2023

En este escrito, quiero reflexionar sobre la pregunta de si existe hoy en Colombia una política institucional que promueva y reconozca la memoria de las víctimas del conflicto. Para responderla, voy a dividir la presentación en tres secciones. Primero, me voy a referir al lugar que ocupa hoy la memoria en las sociedades donde se presentan masivas y, por lo general, sistemáticas violaciones de los derechos humanos. En segundo lugar, en vez de intentar dar una definición de lo que debería ser una política que reconozca la memoria de las víctimas, analizaré cuáles serían los aspectos que dicha política tendría que incluir en las sociedades que quieren hacer el tránsito hacia una paz democrática y respetuosa de los derechos humanos. En la tercera sección, examinaré si los diseños institucionales que, en el marco de la justicia transicional, ha promovido el Estado colombiano a partir de la Ley de Justicia y Paz realmente se pueden considerar como una política coherente de memoria en favor de las víctimas del conflicto.
Arendt y Godard : el pensar en un mundo oscuro
Authors: Añi Montoya Adriana
Published: May 2023

«Puede ser que la realidad sea demasiado compleja para la transmisión oral. La leyenda la recrea de forma que le permite recorrer el mundo». Curioso mensaje, que podría ser un texto de Arendt, pero es pronunciado por una mega computadora, Alpha 60, personaje central del soberbio filme Alphaville de Jean-Luc Godard (1965). Curioso también porque la ciudad «futura» que allí se representa exhibe en su entrada un cartel que reza «Silencio–Lógica–Seguridad–Prudencia». Una cosa no va con otra. La narración de historias puede constituir una fuerza liberadora, promotora de identidad, memoria y transformación. El mensaje de la ciudad, en cambio, augura un mundo donde la conversación y la narración han muerto. El único lenguaje permitido es el de las señales y comandos operativos. Se promete, eso sí, seguridad, siempre y cuando uno se ajuste a la lógica consecuencialista. Por esa misma razón es que el lenguaje ha sido simplificado al máximo, omitiendo palabras subversivas, como «conciencia» y «amor». Obviamente, los afectos debían ser suprimidos porque un ser que ya no se relaciona consigo mismo difícilmente puede hacerlo con el otro. A los habitantes de Alphaville solo les queda prudencia, no la aristotélica, sino la del ratón en el laberinto.
Moda, reificación y utopía: zapatillas de lujo y la estética worn out
Authors: Patiño Núñez Alberto
Published: May 2023

El artículo analiza algunos ejemplares de las llamadas zapatillas "de diseñador", es decir, marcas de élite inscritas en la tendencia estética llamada worn out (desgastada). Describe prácticas y discursos de la industria de la moda, y el lujo y suntuosidad con los que suele estar asociada. Identifica el marco cultural y el mercado de la moda como referentes de identidades e ideales de la época actual. Con base en la teoría crítica y cultural de autores, como Fredric Jameson y Slavoj Zizek, se revisan algunas ideas centradas en las concepciones del pasado, la construcción de la identidad y la creación de lazos sociales. Desde esa perspectiva, se cuestiona si el sentido de lo estético se encuentra despolitizado o si es más bien una producción ideológica.

Biology of the Vegetable Leafminer, Liriomyza sativae (Blanchard) (Diptera: Agromyzidae) on Kidney Bean (Phaseolus vulgaris L.) and Pak Choi (Brassica rapa var. chinensis)
Authors: Tran T.H.D. , Tran D.H.
Published: May 2023

Background: The vegetable leafminer, Liriomyza sativae (Blanchard) is a serious pest of vegetable and ornamental crops in the whole Vietnam. Previous studies indicate that biology of Liriomyza leafminers depends on host plant. The objective of this study was to understand the performance of L. sativae on kidney bean (Phaseolus vulgaris L.) and pak choi (Brassica rapa var. chinensis). Methods: The experiment was carried out at the Laboratory of Entomology, Faculty of Agronomy, University of Agriculture and Forestry, Hue University, Vietnam during 2020 and 2021. The development time of immature stages, longevity and fecundity of L. sativae were investigated on kidney bean and pak choi. Result: The total developmental time from egg to adult emergence of the vegetable leafminer fed on kidney bean was shorter (17.1 days) than that on pak choi (18.2 days). Fecundity of the adults on kidney bean (190.2 eggs) were larger than that on pak choi (73.3 eggs). The results indicated that pak choi was less suitable host plant than kidney bean.

Background: The goal of the current study was to ascertain how well oil cake extracts functioned as nutrient source and seed priming agent for groundnut seeds in order to improve their seed quality attributes. Experiments were conducted on cv. CO 7 variety of groundnut to determine the best oil cake extracts and concentrations for seed priming. Methods: For the experiment, seed priming agents were groundnut, sesame, coconut, cotton and neem extracts from oil cakes. The various concentrations of each oil cake extract, namely 5, 10, 15 and 20%, were made and used to treat seeds with oil cake extracts at their ideal concentration. Result: The seeds pre-treated with oil cake extracts had improved seed quality, including faster germination, higher germination rates, the longest root and shoot lengths, the highest levels of dry matter production and a higher vigour index. The most effective groundnut seed priming agent was found to be 20% groundnut oil cake extract. Hence, the groundnut oil cake produced as a farm byproduct can be successfully used to increase the vigour of the seedlings, simplifying the recycling of agricultural products.
Water Stress Affected Seed Accumulation of Non-reducing Soluble Sugars and Germination Performance of Three Chickpea Cultivars
Authors: Vilakazi B. , Ogola J.B.O. , Odindo A.O. , Ncama K.
Published: May 2023

Background: Water stress may alter the seed chemical composition and cause changes in the concentrations of non reducing soluble sugars in seeds and germination performance of chickpea. We evaluated the effect of water stress during chickpea seed development on seed (i) accumulation of non-reducing soluble sugars, and (ii) vigour and germination. Methods: Three chickpea cultivars (Desi-K, Saina-K and ICCV-K) were subjected to two water regimes (water stress- withholding irrigation after flowering and non-stressed- irrigation at 3-day intervals throughout the crop growth) in a completely randomized design with three replications. Seed size, viability, sugars content, solute leakage, germination percentage and mean germination time were determined from seeds harvested at physiological maturity. Result: Water stress increased the raffinose seed content of Saina-K and Desi-K, decreased the raffinose seed content in ICCV-K, but had no effect on sucrose and stachyose content. Electrical conductivity (EC) increased with water stress in all cultivars, but the increase was greater in ICCV-K (57%) compared to Desi-K (18%) and Saina-K (12%). Non-stressed seeds had larger seed size, higher seed viability and germination percentage and lower EC and mean germination time than stressed seeds. Clearly, sufficient water at seed development stage is crucial for productivity of subsequent crops as it affects seed quality. However, we recommend further studies using a wide range of water stress treatments and chickpea cultivars with different seed size, seed color and seed coat texture.

Understanding the role of cognitive effort within contextual interference paradigms: Theory, measurement, and tutorial
Authors: Getchell Nancy , Shewokis Patricia
Published: May 2023

BACKGROUND:“Contextual interference” (CI) describes a counterintuitive phenomenon related to practice organization when learning multiple tasks that are presented in a non-repetitive order. In CI, the lack of repetitiveness introduces a high level of interference within the learning context such that task performance during initial skill acquisition is frequently poorer than if tasks are practiced in a repetitive fashion. However, these learners often perform better on retention and transfer tasks than individuals who learn within a low CI environment. 
AIM:We provide a tutorial on several novel ways in which researchers can investigate brain activity in a CI paradigm using functional near-infrared spectroscopy: Relative neural efficiency (RNE), relative neural involvement (RNI), and laterality index (LI).
METHOD:RNE integrates measures of cognitive effort and behavioral performance; in high CI learning environments, RNE should initially be poor (high cognitive effort, low behavioral performance), then improve during retention and transfer. RNI provides an index of the relationship among motivation, mental effort, and performance. Finally, LI allows for the exploration of lateralization between the two hemispheres of the cerebral cortex. 
RESULTS:Significant differences were found for total hemoglobin, RNE and LI for the right and left prefrontal cortex regions. The differences were accompanied by moderate-to-large effect size with random using less effort, better performance and was more oriented to goal orientation and learning processes than blocked who focused more on visuomotor attentional components and used more effort with lower behavioral performance scores.
CONCLUSION:RNE, RNI, and LI provide innovative methods to better understand cognitive effort within CI paradigms.
