Children’s digital competence in early childhood education: A comparative analysis of curricula
Authors: Kontkanen Sini , Pöntinen Susanna , Kewalramani Sarika , Veresov Nikolai , Havu-Nuutinen Sari
Published: January 2023

Children’s digital competence (DC) is often poorly supported in early childhood education (ECE). Furthermore, common definition of DC is difficult to find. Therefore, the aim of this comparative curriculum study was to better understand how objectives and content of DC are defined in ECE. Australia and Finland curricula were analyzed applying theory-driven content analysis. The results indicated that in both countries theoretical basis of DC was present: objectives and content of DC referred to (1) technical skills and practices, (2) applying digital technologies, (3) evaluate digital technologies critically, and (4) motivation to participate in a digital culture. However, aims, content, and practical guidelines on the curricula were unclear. This study recommends that ECE curricula should better emphasis and make explicit the key elements of DC and how to holistically foster children’s DC in practice. Further studies to clarify the important elements of DC in ECE curricula frameworks is required.

Published: January 2023

In the present study, we were interested in the appraisal by teachers who have had experience with an individual form of differentiation of the efficiency of grouping learners into homogenous or heterogeneous groups. In the study, seven aspects were thus considered: (1) the learning performance and motivation of learners, (2) the learners’ activity, (3) didactic ways of adapting teaching to diverse learners, (4) the impact on the formation of learners’ personality, (5) cooperation among learners, (6) opportunities for professional development, and (7) cooperation with parents. The research has shown that there is a statistically significant difference between the teachers who teach in homogeneous groups and the teachers who teach in heterogeneous groups in all the seven aspects of the appraisal of the efficiency of grouping learners into homogenous or heterogeneous groups. Regarding most of the assertions, teachers belonging to both groups perceive the way of teaching they perform as having the most advantages.
Kinetic Study of Ru(III) Promoted Oxidation of L-Tryptophan in an Anionic Surfactant Medium by Hexacyanoferrate(III)
Authors: Srivastava Abhishek , Manjusha  , Srivastava Neetu , Naik Radhey Mohan
Published: January 2023

The kinetic investigation of Ru(III) promoted oxidation of L-tryptophan (Trp) by [Fe(CN)6]3- has been performed in anionic sodium dodecyl sulfate (SDS) micellar medium by recording the decrease in absorbance at 420 nm, corresponding to [Fe(CN)6]3- using UV-visible spectrophotometer. Pseudo-first-order condition has been used to examine the progress of reaction as a function of [Fe(CN)63−], ionic strength, [OH-], [SDS], [Ru3+], [Trp], and temperature by changing one variable at a time. The results exhibit that [OH-], [SDS], and [Trp] are the decisive parameter showing an appreciable effect on reaction rate. The reaction exhibits first-order kinetics in the studies concentration range of Ru(III), [Fe(CN)6]3− and at lower [Trp] and [OH-]. The incremental trend observed in the reaction rate with electrolyte concentration shows a positive salt effect. The reaction rate is almost ten times faster in SDS micellar medium compared to the aqueous medium. [Fe(CN)6]3- does not show any appreciable effect on the critical micellar concentration (CMC) of SDS as the polar head of SDS and [Fe(CN)6]3- both are negatively charged. The K+ obtained from K3[Fe(CN)6] and KNO3 decreases the repulsion between the negatively charged heads of the surfactant molecules thereby decreasing the CMC of SDS. The activation parameters also support the outer-sphere electron transfer mechanism as proposed by us.
 
Resumen. El estudio cinético de la oxidación de L-tryptofano (Trp) con [Fe(CN)6]3- asistida por Ru(III), se llevó a cabo en un medio micelar de dodecilsulfato de sodio aniónico (SDS) y se monitoreó utilizando espectrometría de UV-visible midiendo la disminución de la absorbancia a 420 nm, correspondiente al [Fe(CN)6]3-. Para examinar el avance de la reaccción se utilizaron condiciones de pseudo-primer orden en función de [Fe(CN)63−], fuerza iónica, [OH-], [SDS], [Ru3+], [Trp], y temperatura, variando siempre una sola una variable. Los resultados indican, que los parametros decisivos que tuvieron un efecto apreciable sobre la velocidad de la reacción son [OH-], [SDS], y [Trp]. La reacción sigue una cinética de primer orden en el rango de concentraciones de estudio de Ru(III), [Fe(CN)6]3− y a bajas concentraciones de [Trp] y [OH-]. La tendencia de incremento de velocidad de la reacción con aumento de la concentración del electrolito muestra un efecto salino positivo. La velocidad de la reacción en el medio micelar de SDS es casi diez veces mayor que en solución acuosa. [Fe(CN)6]3- no muestra ningún efecto appreciable en la concentración crítica micelar (CMC) de SDS debido a que el grupo polar del SDS (SO3-, cabeza) y el [Fe(CN)6]3- tienen ambos carga negativa. Los cationes K+ provenientes del K3[Fe(CN)6] y KNO3 disminuyen la repulsión entre las cabezas con cargas negativas del surfactante, bajando así la CMC del SDS. Los parámetros de activación apoyan también el mecanismo de transferencia de electrones de la esfera exterior propuesto.

Evaluation of acute lethal response of Corcyra cephalonica to Bacillus thuringiensis Berliner Var. kurstaki, strain ABTS-351, an isolate of strain HD-1
Authors: Deepak Singh  , Isaac L Mathew
Published: January 2023

Bacillus thuringiensis (Bt) is the most successful among other microbial pesticides. The microbe formulations are being implemented in many IPM programs. Among many subspecies, Bacillus thuringiensis Berliner Var. kurstaki subspecies is specifically used against lepidopteran pests. Its strain ABTS-351 (Btk ABTS-351) is the active biocide product in several new Bt formulations and is essentially an isolate of strain HD-1. Efficacy screening is imperative due to chances of pest insects developing resistance to Bt formulations. This study was conducted to characterize Btk ABTS-351 strain for potent insecticidal activity against Rice moth, Corcyra cephalonica larvae in local conditions. The LC50 value (with 95% confidence limits) of Bt on C. cephalonica 4th instar larvae for 24 hr was 65.813 (52.946 – 85.689) mg/mL. This value is comparatively higher than those observed in other lepidopteran larvae. The toxicity and mode of action of this formulation can be used efficiently to manage stored grain pests like C. cephalonica, and also has the potential to be combined with other compatible IPM control strategies.

Saci-Pererê e São Benedito: entidades negras, religiosidade e memórias da escravidão
Authors: Pereira Rocha Elaine
Published: January 2023

O mito do Saci-Pererê e a devoção a São Benedito são parte da tradição cultural brasileira que se estabeleceu principalmente a partir do século XIX. Enquanto a Igreja Católica utiliza os santos negros para reforçar o controle sobre indivíduos escravizados, as memórias da escravidão se registram em entidades afro-brasileiras como o Saci, que traz no corpo o registro da violência da escravidão. O Saci é entidade oposta à São Benedito, pois sua característica principal é a liberdade e a desobediência, enquanto o santo é caracterizado pela servidão. Nesta análise, a narrativa católica sobre São Benedito e as narrativas coletadas por Monteiro Lobato sobre o Saci são examinadas como parte da experiência histórica dos negros no Brasil.

Published: January 2023

Исследован высокоэнтропийный Co - Cr - Fe - Mn - Ni-сплав неэквиатомного состава, полученный по технологии проволочно-дугового аддитивного производства (WAAM). Проанализированы деформационные кривые при растяжении сплава в исходном состоянии и после электронно-пучковой обработки. Установлены зависимости параметров прочности и пластичности, нано- и микротвердости, трибологических свойств от плотности энергии пучка электронов. Анализ поверхности разрушения сплава после электронно-пучковой обработки наряду с областями с вязким механизмом разрушения выявил области с полосовой (пластинчатой) структурой. Обнаружено немонотонное изменение скалярной плотности дислокаций, достигающее максимального значения ~ 5,5 × 1010 см-2 на расстоянии 25 мкм от поверхности облучения. Показано, что электронно-пучковая обработка приводит к снижению прочностных и пластических свойств высокоэнтропийного сплава. Предположено, что дефекты, образующиеся в поверхностных слоях при этой обработке, могут быть одной из причин снижения прочности и пластичности сплава.

A deep understanding of advanced mathematics is essential. This is without doubt. However, mathematics that is applicable on daily life is deemed more important. At least for the ones that does not belong to pure mathemacs field. One des not need to be a mathematics professor to be able to predict commute time to their work or to decide which clothes to buy with given amount of discount. This is also known as mathematical literacy. One of the key features of mathematical literacy is the integration of context. Developing or designing mathematical literacy task with local context is one of efforts to promote students’ mathematical literacy. This is because students are already familiar with the context hence they cam understand the problem statement better. The current study is design research aiming to develop mathematical literacy problems with East Kalimantan context. There are two phases in this research. The first phase is the preliminary phase. Here, PISA 2012 mathematics problems are reviewed and then researchers developed prototype problems with equal level but based on East Kalimantan context. There were nine mathematical literacy problems were developed in this phase. The second phase is the formative evaluation which consists of self evaluation, expert review and field test. From the process, nine valid items of problems with local context for measuring students’ mathematical literacy are obtained.

Sorghum production is seriously threatened by the root parasitic weeds (RPWs) Striga hermonthica and Striga asiatica in sub-Saharan Africa. Research has shown that Striga control depends on eliminating its seed reserves in soil. Several species of the genus
Fusarium (Nectriaceae, Hypocreales) , which have been isolated from diseased Striga plants have proven to be highly pathogenic to all developmental stages of these RPWs. In the present study 439 isolates of Fusarium spp. were found associated with soils from
Sorghum growing fields, Sorghum rhizosphere, or as endophytes with Sorghum roots and seeds, or as endophytes of Striga stems and seeds. Based on multi-locus phylogenies of combinations of CaM, tef1, rpb1 and rpb2 alignments, and morphological
characteristics, 42 species were identified, including three species that are newly described, namely F. extenuatum and F. tangerinum from Sorghum soils, and F. pentaseptatum from seed of Striga hermonthica. Using a previously published AFLP-derived
marker that is specific to detect isolates of F. oxysporum f. sp. strigae, an effective soil-borne biocontrol agent against Striga, we also detected the gene in several other Fusarium species. As these isolates were all associated with the Striga/Sorghum pathosystem,
the possibility of horizontal gene transfer among these fusaria will be of interest to further investigate in future.

Authors: Güzel Barış Can , Demircioğlu İsmail , Gezer İnce Nazan
Published: January 2023

In this study, anatomical, morphometric and volumetric analyses of the mandible of Hamdani sheep were performed using computed tomography (CT) and three-dimensional (3D) software. For this purpose, 16 (eight males, eight females) Hamdani sheep heads were used. Images of these heads were taken on a 64-detector CT device applying 80 kV, 200 MA, 639 mGY, and 0.625 mm section thickness. Scan images of the mandible of each subject were converted into three-dimensional models using 3D software and reconstructed. Surface, volume and linear measurements (24) of the mandible were performed on the models. All the measurements were expressed as mean ± SD. The examinations determined that the mandible's volume and surface area values were more significant in males than females. Mandible length (GOC-ID) was 169.01±0.74 mm, and its height (GOV-CR) was 95.50±0.64 mm in males. In morphometric evaluations, statistically significant differences were observed between males and females in L2 (PC-ID), L6 (GOC-FMN), L14 (MTR-MH), L19(SI), Volume and Surface area measurement parameters (P<0.05). It is thought that the morphometric data obtained will be a reference in pathological conditions, taxonomy studies, and interventional surgical treatment applications to be performed on the site.
Вплив паратипових чинників на показники якості молока при різних технологіях утримання тварин
Authors: Адмін О. Є. , Адміна Н. Г.
Published: January 2023

Метою цього дослідження було встановлення впливу паратипових чинників на продуктивність корів, вміст соматичних клітин у молоці та захворюваність корів на мастит. Усього проаналізовано понад 15 тисяч проб молока, отриманих за умови прив’язного утримання корів та понад 16 тисяч проб – у разі безприв’язного. Середній вміст соматичних клітин у молоці за умови безприв'язного утримання складав 700±11 тис/см3 з мінливістю 141 %, а у разі прив’язного – 411±7 тис/см3 із дуже високим значенням варіабельності цього показника – 209 %. Високі значення мінливості обумовлено біноміальним розподіленням вмісту соматичних клітин. У дослідженнях було визначено силу впливу віку корів, стадії лактації та сезону року на добові надої та якість молока корів. Найменшу кількість соматичних клітин (545±19,3 тис/см3) за умови безприв’язного утримання мали корови першої лактації. Зі збільшенням віку тварин значення цього показника спочатку зростало до третьої лактації (805±28,4 тис./см3), а потім середня кількість соматичних клітин у молоці залишалась майже на одному рівні. За умови прив’язного утримання вміст соматичних клітин у корів шостої лактації і старше (634±53,1 тис у cм3) був майже вдвічі більшим, ніж у первісток (331±9,2 тис. у cм3). Частота реєстрації захворювань на мастит за умови прив’язного утримання в перший місяць лактації складала 17,3±2,33 %, а у другий – зменшувалась до 15,1±2,39 %. Потім протягом лактації кількість корів, хворих на мастит, збільшувалась до 21,5±2,24 % на 11-му місяці лактації (Р<0,05). У разі безприв’язного утримання відсоток випадків захворювання на мастит був найменшим у другому місяці лактації (26,9±1,71 %). Надалі протягом лактації кількість корів, хворих на мастит, збільшувалась до 31,2±1,74 % (Р<0,05). Що стосується сезонних змін показників молока за умови безприв’язного утримання, то середньодобовий надій змінювався від 15,8±0,14 кг у січні до 17,8±0,16 кг у червні, вміст жиру коливався від 3,39±0,011 % у червні до 3,71±0,010 % у грудні, вміст протеїну – від 3,00±0,009 % у вересні до 3,23±0,010 % у березні. Найнижчий вміст соматичних клітин спостерігався у пробах молока, отриманих у січні (380±14,2 тис/см3), а найвищий – 703±17,1 тис/см3 у липні. За умови безприв’язного утримання найбільша частота виявлення маститу спостерігалась у літні (43,0±2,12 %, 48,6±2,14 % і 41,8±2,11 %) місяці, а також у березні (36,8±2,08 %) і листопаді (33,0±1,19 %). Отримані результати можуть бути використані для попередження маститів у корів, що може бути економічно ефективним методом для вирішення питання контролю якості та безпечності молока на виробництві у сучасних умовах.

Published: January 2023

Інфекційний ринотрахеїт як герпесвірусна інфекція значно поширений серед котів і проявляється гострим перебігом ураження очей та органів дихання. Незважаючи на значні наукові напрацювання щодо діагностики та лікування хворих тварин, актуальним залишається питання вибору ефективних засобів специфічної профілактики. Метою роботи було з’ясування ефективності застосування різних вакцин провідних виробників проти інфекційного ринотрахеїту котів. Для досягнення поставленої мети потрібно розв’язати такі завдання: дослідити поширення хвороби, особливостей сезонності та вікової сприйнятливості. Дослідження виконували в умовах приватної ветеринарної клініки м. Харкова 2020–2021 років. Встановлено, що захворюваність котів на герпесвірусну інфекцію склала 25,8 %. Сезонні коливання за наявності інфекційного ринотрахеїту визначилися у весняно-осінній період з найбільшою кількістю випадків у жовтні-листопаді (28,0 %) та у березні-квітні (31,0 %). Аналіз вікової динаміки показав, що коти найбільш схильні до герпесвірусної інфекції у віці 10 тижнів (23,0 %) та у віці 12 тижнів (20,5 %), мінімально чутливі до хвороби у віці 3 роки і старше (2,5 %). Також реєстрували випадки захворювання серед котів 6-ти річного віку і старше (15,3 %). Результати аналізу епізоотологічних показників щодо інфекційного ринотрахеїту котів указують на значне його поширення в умовах м. Харкова та вимагають науково обґрунтованого застосування ефективних специфічних засобів. У результаті дослідження ефективності застосування різних вакцин провідних виробників проти інфекційного ринотрахеїту котів препаратами вибору стали вакцини «Нобівак TRICAT Trio» та «Zoetis Felocell 4», які забезпечували 100 % ефективність при застосуванні кошенятам у 9–12-ти тижневому віці. Вакцини «PureVaxRCPCH» та «Feligen CRP» при застосуванні їх кошенятам у 8-ми тижневому віці показали ефективність 86,0 % та 71,0 % відповідно. Для покращення ефективності застосування вакцин необхідно регулярно запроваджувати моніторингові дослідження з виділенням циркулюючих штамів вірусу в певному регіоні з метою аналізу відповідності їх зі складом вакцинних антигенів. Важливим питанням залишається з’ясування рівня загальної резистентності та колострального імунітету сприйнятливого молодняку перед запровадженням щеплення.
A single nucleotide variant on chromosome 8, rs4130794, distinguishes patients with normal-like breast cancer.
Authors: Mamoor Shahan
Published: January 2023

Molecular subtypes including the normal-like subtype drive patient outcomes in human breast cancer but the biological basis underlying subtype-specific disease is not completely understood (1-4). We mined published microarray data (5) to discover in an unbiased fashion the most distinguishing genetic features of tumors of each breast cancer molecular subtype. We identified a single nucleotide polymorphism on chromosome 8, rs4130794, as among the most significant genetic differences in the tumors of patients with normal-like breast cancer. Sequence variation at rs4130794 may be important in understanding differences in genetic background that favor development of normal-like subtype human breast cancer.
Towards a business model for second-life batteries - barriers, opportunities, uncertainties, and technologies
Authors: Júnior Carlos Rufino
Published: January 2023

Electric vehicles (EVs) and the recent pandemic outbreak give cities a new trend to primarily private and shared mobility with low noise and less air pollution. Crucial factors for the widespread of EVs are the electrical charging infrastructure, driving range, and the reduction of the cost of battery packets. For this reason, there is a massive effort from manufacturers, governments, and the scientific community to reduce battery costs and boost sustainable electrical production and distribution. Battery reuse is an alternative to reduce batteries’ costs and environmental impacts. Second-life batteries can be used in a wide variety of secondary applications. Second-life batteries can be connected with off-grid or on-grid photovoltaic and wind systems, vehicle charging stations, forklifts, and frequency control. The present work aims to analyze the main challenges imposed on the reuse of batteries, the leading technologies for their reuse, and the different types of batteries in terms of their feasibility for second-life use. The main novelty of this work is the discussion about the barriers, opportunities, uncertainties, and technologies for the second life market. Here we summarize the present state of the art in reusing lithium-ion batteries discussing technical and economic feasibility, environmental impacts, and perspectives. The results show five business models that have been proposed in the literature, three types of markets for trading second-life batteries, and the main opportunities and barriers for each actor in the battery supply chain.S
How does divided attention hinder different stages of episodic memory retrieval?
Authors: Ataseven Nursena , Ünver Nursima , Günseli Eren
Published: January 2023

Episodic memory retrieval is crucial for survival and can be impaired by divided attention. However, since memory retrieval consists of different stages, divided attention can impair each stage uniquely, leading to retrieval failures. It is important to acknowledge the multistage characteristics of episodic memory retrieval to understand the cognitive mechanisms that mediate the relationship between memory retrieval and divided attention. Here we attempt to unravel the role of divided attention in gating the access to long-term memories through its unique impact on a non-exhaustive list of six stages of a memory retrieval task: processing of retrieval cue, initiating a retrieval mode, searching for the target memory, retrieving, and reactivating the target memory, decision-making, and motor preparation to produce a response. We describe how each stage might be affected by divided attention. To do so, we review not only studies on memory retrieval but also areas that constitute different stages described above given the lack of extensive research that explores the role of attention for each stage. We hope this work will contribute to carefully controlling and manipulating how different stages are affected by attention, which in turn will improve our understanding of the relationship between attention and memory retrieval.

Support for populism has risen substantially during the past two decades. We investigate the extent to which the rising electoral demand for populist parties and causes can be explained by negative affect. Globally, negative affect has risen rapidly in recent years and has even been referred to by some as a "blind spot'' for politicians and policymakers who have failed to recognize its significance. We use a multi-modal, multi-method empirical approach, using data from a diverse set of geographical and political contexts. Across four studies, we demonstrate that negative affect – measured via self-reported emotions as well as automated text analyses of over 2 billion Tweets – predicts i) individual-level populist attitudes in global survey data (Studies 1a and 1b), ii) longitudinal changes in populist party vote shares at general elections in European countries (Study 2), iii) area-level Brexit voting in the 2016 UK referendum (Study 3) and iv) county-level vote shares for Donald Trump in the 2016 and 2020 US presidential elections (Studies 4a and 4b). We find that negative emotions—such as fear and anger as well as more often overlooked low-arousal negative emotions like depression and sadness—are predictive of populist beliefs as well as voting. We establish a boundary condition by demonstrating that the relationship does not hold for populist politicians who are already in power: Like other incumbents, governing populists do not benefit electorally when their constituents continue to experience negative affect after they have been elected. With negative affect being fertile ground for populist support, our research calls for politicians to alleviate rather than avail themselves of negative affect.

The effects of graded doses of ethanol extract of Pleurotus ostreatus (EEPO) on the sperm quality and haemo-biochemical parameters of the male Wistar rats were studied. Twenty-five adult male rats were randomly assigned into 5 groups A-E, (n=5). Groups A, B, C, and D were treated with 200, 400, 600 and 800 mg/kg of EEPO respectively while group E received 0.2 ml Propylene glycol serving as the control. Animals were treated for 14 days after which samples were collected. Sperm motility, liveability and sperm count of EEPO-treated rats in groups A, B, C and D showed a dose-dependent increase compared to the control. The treatment significantly (p<0.05) increased the PCV, Hb, RBC and platelets counts of rats across the treated groups A-D. There were no significant changes (p>0.05) in other haematological parameters except for a marked reduction in the WBC count of group B. The mean ALB and TP increased across the treated groups when compared to the control). It was concluded that ethanol extract of P. ostreatus produced a dose-dependent increase in sperm motility, liveability, sperm count, PCV, Hb, RBC, TP and ALB, thereby enhancing the fertility of the rats, especially at higher doses. Hence, the plant should be considered as feed supplements for the male breeding stock.

This study attempts to document the lichen species and their distribution in different areas of Kathmandu valley, Nepal. Twenty sampling sites with different degrees of air pollution categorized as disturbed (industrial, heavy traffic and residential areas) and undisturbed areas (clean area) were selected for the study. Sampling was done using the quadrat method. To enumerate the total number of lichen species found in Kathmandu valley, lichen specimens were collected from inside as well as outside the quadrats. A total of 97 species of corticolous lichens belonging to 21 families and 44 genera were recorded from the study sites. Parmeliaceae was the largest family followed by Graphidaceae. The importance value analysis showed that Candelaria concolor (115.2), Dirinaria aegialita, Lepraria sp., Phaeophyscia hispidula var. hispidula and Physcia sorediosa (106.02) are the most common and dominant lichen species in Kathmandu valley. Among the most common and dominant lichen species, Candelaria concolor, Dirinaria aegialita, Phaeophyscia hispidula var. hispidula and Physcia sorediosa were found concentrated in heavy traffic areas whereas Lepraria sp. in the industrial areas. A higher number of lichen species (70%) was recorded in undisturbed areas than in disturbed areas (50%). These study confirm that the distribution of lichen flora is strongly influenced by degrees of pollution. This in turn suggests that lichens can be used as bio indicators of air quality in the Kathmandu valley.

Published: January 2023

The bacteriocinogenic strain Lactobacillus paracasei spp. paracasei BN ATC 8w was isolated from traditional «Motal» cheese and has strong antimicrobial activity against some Gram-positive and Gram-negative bacteria. The in situ activity of the strain was studied in skimmed milk against E. coli ATCC 25922 for 24 hours. Cooperative cultivation of the active strain L. paracasei spp. paracasei BN ATC 8w with E. coli ATCC 25922 сells in skimmed milk at a concentration of OD 0.28 after 24 hours (300C) led to a decrease up to almost 50% of the concentration of E. coli, which was found in the absence of an active strain in the medium. This indicates the in situ efficiency of the L. paracasei spp. paracasei BN ATC 8w in skim milk for the biological protection of dairy products from opportunistic pathogens.

Published: January 2023

In the world, over the years, the use of hydrocarbon resources is decreasing, and their place is being replaced by ecologically clean alternative and renewable energy sources. Therefore, the world is paying a lot of attention to improved devices based on photoelectric batteries. Conducting targeted scientific research in this direction is one of the urgent issues of the present time. This article presents the results of comparing the electrical parameters of photovoltaic and photothermal batteries based on them in natural conditions. The experiments were carried out on three traditional photoelectric batteries with different materials and constructions, as well as photothermal batteries made on their basis. All batteries are installed in a mobile structure, and two planes (reflectors) that reflect sunlight are installed along the long side of the device connecting the batteries. In the same conditions, the intensity of solar radiation is increased with the help of reflectors that return light to photoelectric and photothermal batteries. On the front surface of the photovoltaic batteries, a vertical (90) fall of the sun's rays is provided. As a result, their electrical parameters changed to different values depending on the type of material and construction. Compared to traditional photoelectric batteries, photothermal batteries produced 1.3-1.4 times more electricity depending on the type of material. In the results of the experiment, data were obtained on the open circuit voltage, short circuit current and power of photoelectric and photothermal batteries in hot climate conditions. According to results, the high indicators in terms of electrical parameters are monocrystalline photoelectric and photothermal batteries based on them.

excitation by nanosecond laser pulses has been studied. It was shown that the maximum of stationary absorption exhibits as a wide structureless band with a maximum at about 520–540 nm. The transient absorption band of gold nanoparticles with a maximum at about 430 nm has a fine structure with a frequency of maxima of 6–8 nm and it does not depend on the size of the nanoparticles. The absorption duration decreases with a decrease in the average size of nanoparticles. The lifetime of transient absorption is equal to 23±2 and 19.5±2 ns for large and small particles, respectively. The nanosecond lifetime of the transient absorption of Au nanoparticles is the result of a prolonged relaxation process in the “interface of Au nanoparticle–solvent molecule” system as a manifestation of hindered heat exchange with the environment.
Increasing precision in the management of pediatric neurosurgical cerebrovascular diseases with molecular genetics

Published: January 2023

Recent next-generation DNA and RNA sequencing studies of congenital and pediatric cerebrovascular anomalies such as moyamoya disease, arteriovenous malformations, vein of Galen malformations, and cavernous malformations have shed new insight into the genetic regulation of human cerebrovascular development by implicating multiple novel disease genes and signaling pathways in the pathogenesis of these disorders. These diseases are now beginning to be categorized by molecular disruptions in canonical signaling pathways that impact the differentiation and proliferation of specific venous, capillary, or arterial cells during the hierarchical development of the cerebrovascular system. Here, the authors discuss how the continued study of these and other congenital cerebrovascular conditions has the potential to replace the current antiquated, anatomically based disease classification systems with a molecular taxonomy that has the potential to increase precision in genetic counseling, prognostication, and neurosurgical and endovascular treatment stratification. Importantly, the authors also discuss how molecular genetic data are already informing clinical trials and catalyzing the development of targeted therapies for these conditions historically considered as exclusively neurosurgical lesions.
Weathering the storm: a single-institution experience with paroxysmal sympathetic hyperactivity after brain tumor resection in pediatric patients
Authors: Bouchal Samantha M. , Naylor Ryan M. , Daniels David J.
Published: January 2023

OBJECTIVE

Paroxysmal sympathetic hyperactivity (PSH) is a complication of severe traumatic or hypoxic brain injury characterized by transient episodes of tachycardia, tachypnea, hypertension, hyperthermia, diaphoresis, and/or dystonic posturing. Posttraumatic "sympathetic storms" are associated with poor outcomes. PSH rarely occurs after brain tumor resection in pediatric patients; only 4 cases have been published since 1929. Thus, the authors sought to report their experience with postcraniotomy PSH in pediatric brain tumor patients.

METHODS

A retrospective study of patients younger than 18 years of age who underwent craniotomy for brain tumor resection at a single center by a single surgeon over a 7-year period was performed. A clinical diagnosis of postoperative PSH was recorded. Recorded outcomes included the interval between surgery and initiation of cytotoxic therapy, need for long-term CSF diversion, length of hospital stay, and survival.

RESULTS

Of the 150 patients who were included for analysis, 4 patients were diagnosed with postoperative PSH for an overall occurrence of 2.7%. PSH patients were younger than non-PSH patients (1.8 ± 0.4 years vs 9.2 ± 5.3 years, p = 0.010) and tended to have intraventricular tumors close to the thalamus, basal ganglia, and/or brainstem. PSH patients experienced longer hospital admissions (44.3 ± 23.4 days vs 6.8 ± 9.4 days, p = 0.001), a shorter interval between surgery and initiation of cytotoxic cancer-directed therapy (14.3 ± 8.0 days vs 90.7 days ± 232.9 days, p = 0.011), and increased need for long-term CSF diversion compared with non-PSH patients (75% vs 25%, p = 0.005). At the last follow-up, 50% of PSH patients had died compared with 13% of non-PSH patients (p = 0.094).

CONCLUSIONS

PSH is a rare postoperative complication that may affect young children with periventricular tumors and is associated with poorer clinical outcomes. Increasing awareness of this condition is vital to improving patient outcomes.

У дослідженні виявлено особливості демографічних тенденцій України та окремого регіону і вибіркового регіонального прогнозування з розподілом населення за параметрами місцевості для цілей екологічного проєкту. Отримані результати засвідчили наявність різних статистичних конфігурацій демографічної динаміки у країні та регіоні, а також її відмінності у сільській та міській місцевості. У межах дослідження було кількісно підтверджено спадні демографічні тенденції в Україні і було з’ясовано, що на Закарпатті вони відрізняються. Виявлені відмінності стосуються періоду виникнення «демографічного хреста», конфігурації динаміки, характеру природних та міграційних приростів/спадів та їх впливів на загальну демографічну картину. В цілому Закарпаття за досліджуваний період демонструвало більшу демографічну стабільність та наявність приростів населення протягом тривалого періоду, хоча за останні роки динаміка теж змінилася. Авторами було підтверджено важливість контекстного аналізу для вибору методу демографічного прогнозування та можливість застосування варіативних часових рядів для отримання надійніших статистичних прогнозів.
