Electron Heating by Magnetic Pumping and Whistler-mode Waves
Authors: Frantsuzov Viktor A. , Artemyev Anton , Shi Xiaofei , Petrukovich Anatoli A.
Published: February 2024

The investigation of mechanisms responsible for the heating of cold solar wind electrons around the Earth’s bow shock is an important problem in heliospheric plasma physics because such heating is vitally required to run the shock drift acceleration at the bow shock. The prospective mechanism for electron heating is magnetic pumping, which considers electron adiabatic (compressional) heating by ultralow-frequency waves and simultaneous scattering by high-frequency fluctuations. Existing models of magnetic pumping have operated with external sources of such fluctuations. In this study, we generalize these models by introducing the self-consistent electron scattering by whistler-mode waves generated due to the anisotropic electron heating process. We consider an electron population captured within a magnetic trap created by ultralow-frequency waves. Periodical adiabatic heating and cooling of this population drives the generation of whistler-mode waves scattering electrons in the pitch-angle space. The combination of adiabatic heating and whistler-driven scattering provides electron acceleration and the formation of a suprathermal electron population that can further participate in the shock drift acceleration.
The prognostic role of markers of systemic inflammation in patients with metastatic lung cancer receiving immunotherapy: A comprehensive review of the literature
Authors: Zlatanova Tanya , Arabadjiev Jeliazko
Published: February 2024

Lung carcinoma stands as a prevalent malignancy characterized by a distressingly elevated fatality rate. Immunotherapy, administered either as a monotherapy or together with chemotherapy, represents the primary therapeutic approach for the majority of individuals grappling with advanced non-small cell lung cancer. The influence of systemic inflammation in fostering cancer dissemination and progression is a well-documented phenomenon. This literature review examines contemporary indices and scoring systems, which have emerged as informative indicators of systemic inflammation in recent years. These indices and scores are valuable prognostic and predictive elements in assessing treatment response among patients with metastatic lung cancer undergoing immunotherapeutic treatment.

Published: February 2024

Research on complete mitochondrial genomes can help in understanding the molecular evolution and phylogenetic relationships of various species. In this study, the complete mitogenome of Hua aristarchorum was characterized to supplement the limited mitogenomic information on the genus Hua. Three distinct assembly methods, GetOrganelle, NovoPlasty and SPAdes, were used to ensure reliable assembly. The 15,691 bp mitogenome contains 37 genes and an AT-rich region. Notably, the cytochrome c oxidase subunit I (COX1) gene, commonly used for species identification, appears to be slow-evolving and less variable, which may suggest the inclusion of rapidly evolving genes (NADH dehydrogenase subunit 6 [ND6] or NADH dehydrogenase subunit 2 [ND2]) as markers in diagnostic, detection, and population genetic studies of Cerithioidea. Moreover, we identified the unreliability of annotations (e.g., the absence of annotations for NADH dehydrogenase subunit 4L [ND4L] in NC_037771) and potential misidentifications (NC_023364) in public databases, which indicate that data from public databases should be manually curated in future research. Phylogenetic analyses of Cerithioidea based on different datasets generated identical trees using maximum likelihood and Bayesian inference methods. The results confirm that Semisulcospiridae is closely related to Pleuroceridae. The sequences of Semisulcospiridae clustered into three clades, of which H. aristarchorum is one; H. aristarchorum is sister to the other two clades. The findings of this study will contribute to a better understanding of the characteristics of the H. aristarchorum mitogenome and the phylogenetic relationships of Semisulcospiridae. The inclusion of further mitochondrial genome sequences will improve knowledge of the phylogeny and origin of Cerithioidea.

Published: February 2024

Glass fiber-reinforced plastics (GFRP) have been produced in large quantities for over half a century and nowadays their waste has become a problem worldwide. Their recycling is difficult because they are predominantly manufactured from thermosetting matrices that are not suitable for secondary processing. Only few technologies are able to target full-scale utilization of residual mechanical performance at recycling, with the replacement of gravel in asphalt concrete being one of them. The possibility of introducing crushed GFRP (GFRP crumb) into asphalt concrete and its impact on mechanical characteristics have been investigated in our study. As the source of GFRP, road noise-protection fence was chosen due to large quantities of its waste accumulated in urban economy. Several approaches to produce crumbs were attempted with only shredding being successful. The GFRP crumb has provided excellent mechanical performance of asphalt concrete fabricated by standard routine. In particular, the improvement in compressive modulus was 40%, even under conditions of elevated asphalt concrete temperature at 50 ℃. Besides, introduction of GFRP crumb reduced the overall weight of asphalt concrete mixture, providing further reduction of a carbon footprint. The results obtained indicated that recycling of GFRP waste as replacement of gravel in asphalt concrete provides an economically and environmentally safe solution.
Shock stability of a novel flux splitting scheme
Authors: Wei Weiping , Shang Youlin , Jiao Hongwei , Jia Pujun
Published: February 2024

This article introduced the HLL-CPS-T flux splitting scheme, which is characterized by low dissipation and robustness. A detailed theoretical analysis of the dissipation and shock stability of this scheme was provided. In comparison to Toro's TV flux splitting scheme, the HLL-CPS-T scheme not only exhibits accurate capture of contact discontinuity, but also demonstrates superior shock stability, as evidenced by its absence of 'carbuncle' phenomenon. Through an examination of the disturbance attenuation properties of physical quantities in the TV and HLL-CPS-T schemes, an inference was derived: The shock stability condition for an upwind method in the velocity perturbation was damped. Theoretical analysis was given to verify the reasonableness of this inference. Numerical experiments were carefully selected to test the robustness of the new splitting scheme.

Published: February 2024

The present study sought to (1) assess the needs in the development of the teacher training curriculum on providing learning experiences for promoting social development among persons with autism spectrum disorder (ASD), (2) develop the curriculum, and (3) examine its effectiveness. A mixed-method approach and research and development were adopted. The data were collected during July 2022–April 2023. The results are reported: 1. A review of documents, literature and related studies showed that teacher preparation was required for promoting persons with ASD’s social development. Additionally, the survey indicated that the school directors’ primary need for self-improvement was the frequency of attending training programs (PNIModified = 0.54), while that of the teachers was knowledge and understanding of promoting social development (PNIModified = 0.21). Also, the school directors’ strongest need in providing learning experiences was continuous promotion of social development (PNIModified = 0.47), and that of the teachers was implementation of learning activities based on lessons plans (PNIModified = 0.21). 2. The developed curriculum comprised eight components: rationale, objectives of the curriculum, contents, training activities and methods, training materials, durations, venues, and measurement and evaluation. Concerning its quality, the curriculum achieved a high level of suitability (x = 4.38, S.D. = 0.16). 3. After the curriculum implementation, the teachers achieved higher post-training scores (x = 22) than their pre-training scores (x = 17.20) and were most satisfied (x = 4.71, S.D. = 0.08). Provision of learning experiences achieved a mean score of 84.67%.

Published: February 2024

The purpose of this study is to provide an interdisciplinary approach to fractals within the traditional school curriculum. The proposed activities are expected to help teachers to provide a comprehensive and engaging learning experience for students that fosters deeper understanding, creativity, and connections within the sciences. Fractals are complex geometric shapes that are self-similar, and therefore exhibit similar patterns at every scale. They are created by repeating a simple process over and over. Fractals differ from traditional geometric shapes because they are non-regular, but are very common in nature, such as clouds, mountains, trees and snowflakes. Also fractals are impressive mathematical creations and can contribute a lot to the understanding of Junior High School mathematics because they could be fun and at the same time an exciting way to introduce many areas of mathematics and physics. By connecting fractals to different mathematical concepts and applications, Junior High School students can develop their problem-solving skills and gain a deeper appreciation for the beauty and complexity of mathematics.
Leonardo Sciascia e il racconto-inchiesta: Una storia semplice?
Authors: Lovito Giuseppe
Published: February 2024

In questo articolo cerchiamo di ripercorrere la “storia” di lunga data del rapporto di Sciascia con il racconto-inchiesta, che ha sviluppato nel corso della sua varia produzione saggistico-letteraria, a partire da Le parrocchie di Regalpetra fino a Una storia semplice, cioè dal primo all’ultimo testo narrativo pubblicato in vita. In particolare, attraverso l’analisi delle sue opere più rappresentative da questo punto di vista, mostriamo che questa storia è tutt’altro che “semplice” e che Una storia semplice può, in questo senso, essere considerata anch’essa, a nostro avviso, come un libro-testamento, in quanto illustra emblematicamente la sua travagliata riflessione sul nesso significativo in essa istituito tra (contro)narrazione e potere, verità e giustizia, autore e lettore.

Health management and sustained mental comfort requires a multidisciplinary approach, with a holistic strategy for maintenance of overall wellbeing. Therapeutic interventions for maternal health need to be designed in such a way that it permits mitigation and prevention of the adverse influences on the health of mother and child both. Good gut health has a significant impact on motivation, and higher cognitive functions involving the neuro-immuno-endocrine mediators. The study aimed to understand the knowledge, attitude and practices of expectant mothers during their pregnancy towards the use of probiotics from different cities of Rajasthan, India. Results of the survey study suggested that a considerable number of mothers were unaware about the health benefits of probiotics consumption during and post-pregnancy and due to partial and ambiguous knowledge towards probiotics, maternal subjects also showed characteristics of disbelief on probiotics consumption during and post-pregnancy, which further contributed towards the decreased consumption of probiotics during and post-pregnancy.

Building the coaching capacity of aspiring leaders is a theme regularly seen in professional learning standards for education leaders. The ability to coach others and provide meaningful feedback is an important leadership skill due to its impact on shifting practice and positively affecting student learning. An urban district in Southern California has long included coaching practice as a professional standard in its preparation, promotional, and professional development programs for school leaders. The District's in-house preliminary administrative services credential program is a one-year, tuition-waived, job-embedded, school leader preparation program. The results show the District's candidates not only have a 100% pass rate, they are scoring at a higher level than the state average.
An African American Male Principal's Experience of Being a Flexible Leader While Balancing Authenticity and Diplomacy
Authors: Taylor III Hervey
Published: February 2024

Without the ability to regularly interact with peers who look like them and come from similar backgrounds, it is very difficult for school principals of color (SPOC) and African American male principals (AAMP) to successfully lead a school. Some white school administrators may periodically offer to assist or mentor SPOC and AAMP through certain administrative experiences. However, because of cultural background differences, they may not be able to address the unique needs of SPOC and AAMP. That disparity can be addressed by an experienced SPOC or AAMP who speaks the same language and has traveled a similar educational pathway successfully. In this chapter the author focuses on sharing experiences as an African American school principal through the lens of authenticity and diplomacy. Since SPOCs have challenges to becoming and remaining school leaders and African American principals face an even greater challenge in this area, the author strives to enhance their administrative leadership experience and practice, by sharing his story.
The effectiveness of powdery formulations of long pepper (Piper longum L.) and sweet flag (Acorus calamus L.) to combat the cowpea weevil (Callosobruchus maculatus F.) on stored mung beans
Authors: Keerthika S. , Niranjana R. F.
Published: February 2024

The study aimed to evaluate the efficacy of Piper longum L. fruit and Acorus calamus L. rhizome powders in counteracting the Callosobruchus maculatus F. attacks on the mung bean. People frequently consume mung beans; thus, the insecticides, which are used to prevent seeds from infestations by storage pests, should be formulated in such a way that they can be readily removed from grains prior to cooking; for that reason, powdery formulations were selected. Neem plant (Azadirachta indica A.) gum was pulverized and incorporated as adjuvant according to weight. 100 g of mung bean seed lots were individually exposed to powdery formulations of 80%, 90% and 100% of P. longum and A. calamus, respectively and 100% of adjuvant, along with control. Consequently, five pairs of unsexed C. maculatus were introduced into eight treatments, with three replicates and laid out in the Completely Randomized Design. This experiment was designed to evaluate the adult survival, ovipositional capacity, adult emergence of the F1 and F2 generations and developmental period of C. maculatus, and weight loss in mung bean seeds. Simultaneously, qualitative analysis was done to determine the presence of alkaloids, flavonoids, phenol, tannin, steroids, cardiac glycosides, saponin, and anthraquinone phytochemicals in selected botanicals. Data were subjected to the analysis of variance aided by SAS 9.4 version and means were separated by using the Duncan Multiple Range Test at the 5% significance level. According to the statistical analysis, mung beans treated with 100% A. calamus showed no survival of C. maculatus two days after treatment, whereas those treated with 90% A. calamus powdery pesticide showed 3.3% survival. Though minimum cumulative number of eggs was detected in 90% and 100% (11.0, 9.7) of A. calamus treated mung bean seeds, zero progeny development was observed until 60 days; therefore, no weight loss was detected on mung bean seeds. The study concluded that 90 and 100% of the powdery insecticides from A. calamus were efficacious in safeguarding the mung bean from C. maculatus.

Published: February 2024

Ground water is an extremely valuable resource and pollution of ground water resources is a matter of serious concern. Though more than 80% of people in the Jaffna region, rely on ground water self-supply wells, the extent to which self-supply wells delivers safe water and the associated risk factors for contamination remain unclear. In response to community requests and the National Water Supply & Drainage Board's (NWS&DB) provision of water from four ground water wells through 150m lateral pipes, a study was initiated to assess quality of well water within a 1.5km radius from the NWS&DB wells. This study involved the evaluation and mapping of groundwater quality parameters and the application of the Water Quality Index (WQI) to determine water potability. The study revealed that numerous parameters, such as turbidity, color, TDS, total hardness, total alkalinity, chloride, fluoride, total iron, calcium, and sulfate concentrations, exceeded SriLankan drinking water standards, while pH, nitrate, nitrite, and total phosphates remained within acceptable limits in all 120 wells. Heavy metals like arsenic and cadmium were absent in all samples. Microbiological results showed contamination with total coliformand E.coli bacteria throughout the study area. Considering physical and chemical parameters, the WQI values ranged from 4.5 to 287.2, with 72 wells suitable for drinking. However, when microbiological parameters were factored in, only three wells were deemed safe for drinking, underscoring the critical necessity for aquifer protection, thorough cleaning, and the immediate implementation of regular well chlorination or disinfection measures tosafeguard the health and well-being of the community.

The purpose of this study was to assess the apoptotic effects of punicalagin alone and in combination with 5-fluorouracil (5-FU) on laryngeal squamous cell carcinoma (Hep-2) cell line. Hep-2 cells were cultured and divided into four groups: Group 1 received no therapy and served as control, Group 2 received 5-FU only, Group 3 received punicalagin only, and Group 4 received a combination of 5-FU and punicalagin. After 48 hours of incubation, cellular changes were examined under an inverted microscope. The methyl thiazolyl tetrazolium assay, caspase-3 gene level, and vascular endothelial growth factor (VEGF) level were assessed. The control group showed the highest mean value of cancer cell proliferation rate (1.595±0.58), followed by the punicalagin group (1.263±0.447), then the 5-FU group (0.827±0.256), while the combination group showed the lowest proliferation rate (0.253±0.111). The combination group showed the highest mean value of caspase-3 concentration (3.177±0.736), followed by the 5-FU group (1.830±0.646), and punicalagin group (0.741±0.302), while the control group showed the lowest mean value (0.359±0.117). Regarding VEGF levels, the control group had a statistically significant higher mean value, followed by the punicalagin and 5-FU groups, and finally, the combination group which showed the lowest value. Punicalagin exerts an anticancer effect through anti-proliferative action and induction of apoptosis on Hep-2 cell line. Combining punicalagin with 5-FU potentiates its anti-proliferative, apoptotic, and anti-angiogenic actions. It, further, helps in mitigating the putative side effects of 5-FU by reducing the dose required for its therapeutic effects.

A simple C- grid is constructed for the purpose of studying the effect of a sheet of ejection jet installed at the thicker portion of the trailing edge to investigate possible effects it could have upon the aerodynamic lift and drag of the UCAV 1303 model. The blowing seemed to improve the lift and make a marginal improvement upon drag.
Prediction of Molecular Colorectal Cancer Recurrence Using Machine learning
Authors: Moria Kawthar
Published: February 2024

Understanding the attributes that affect the occurrence of colorectal cancer can be very effective to developing methods that help in preventing this cancer disease. In many cases, a patient who receives cancer treatment must be kept under observation for a long period of time as cancer would most probably recur. The proposed approach is a feature-driven classification that predicts related features that greatly influence colorectal cancer recurrence and then uses these features to classify cases using different machine learning approaches. The microarray gene expression is combined with other demographic and clinical data to determine the relation to the recurrence measured using the statistical MRMR method. Then the best features among them that are highly correlated are selected. Different machine learning approaches were used to predict the recurrence, including the Quadratic SVM and the Gaussian Naïve Based approaches with and without the resulting correlated features. Performance improved dramatically when the related features were utilized. Using MRMR, we found that the accuracy of applying Gaussian Naïve Based is calculated as 80.6%, which outperformed the accuracy for Quadratic non-linear SVM by 77%. More data can be used in the future to improve the performance.

Доказано, что оператор $H$ замыкаем и его минимальное замыкание является неотрицательно определенным самосопряженным оператором (при этом критическое значение $b_*$ зависит от $\alpha $). Хотя оператор $H$ неотрицательно определен, потенциал $V(x)$ может принимать отрицательные значения, например, при $b_*<0$ для всех $0<\alpha <1$. Для уравнения $Hu=v$ существует функция Грина $g_H(x,y)$ - интегральное ядро оператора $H^{-1}$. Получены точные нижняя и верхняя оценки отношения функций Грина $g_H(x,y)$ и $g_L(x,y)$.

Published: February 2024

Background: The mapping exercise within the study ar ea on a scale of 1:25,000 was carried out to study the rocks, determine their distribution, composition, structures and assess the economic potential of the area. Objectives: The geology mapping aim to identify and understand the various geological structures present in the area to gain insights into the tectonic history and deformation processes that have shaped the area and to identify the minerals present in the rock, to understand the rock formation, composition and potential geologic processes involved. Method: Method of mapping involved road, footpath, rivers and stream traverses. Representative rock samples were collected for petrographic studies and geochemical analysis to establish the geology of the study area. Result: The study area which is part of Sheet 148, Toro SE is entirely typical of the Nigerian Basement Complex and is underlain by the following rock units: Migmatitic Gneiss, Granite gneiss, mica schist and porphyritic granite. The Migmatitic Gneiss constitutes the largest group of the rock units covering more than 45% of the mapped area and trending mainly NW/SE with few exceptions in an almost N/S to NE/SW direction. It is pertinent to know that almost E-W structures were also observed which forms relics of the older structure believed to have been affected by the eburnean (possibly) orogenic event. The granite gneiss shares boundary mainly with the migmatitic gneiss showing a weak foliation of light and dark materials. The mica schist is exposed at the western end, highly weathered with a general trend of NW/SE. The porphyritic granite intruded both the migmatite and granite gneiss occurring prominently as hilly and bouldery outcrops. However, flat lying low lying was also observed in some other localities. With respect to field observation and petrographical study the lithologies encountered were grouped into nine (9) categories- homogeneous, inhomogeneous, stromatic, banded orthogneiss, nebulitic, apo granite, pegmatite, intermediate and schist.Conclusion: Field evidence suggests that the study area has undergone an episode of metamorphism and deformations as depicted by the structural features like preferred orientation of the mineralogical and lithological units. It was also observed from the field measurements, that the main structural trend within the study area is from NNE/SSW.

Published: February 2024

In this study, the nutrients, phenolics, minerals and fatty acids compositions of the seed kernels of Telfairia pedata was determined using standard laboratory procedures. The results from Gas Chromatography - Mass Spectrometry (GC-MS) indicated that the studied T. pedata was composed of 2,4-bis(1,1-dimethylethyl)phenol (9%), pentadecanol (2%), di(2- propylpentyl)phthalic acid (5.8%), myristic acid (1.5%), palmitic acid (14%), linoleic acid (44%) and others. Quantification of fatty acids showed linoleic acid (500 μg/mL), oleic acid (350 μg/mL), 5Z,8Z,11Z,14Z-eicosatetraenoic acid (403 μg/mL), palmitic acid (410 μg/mL), heneicosanoic acid (462 μg/mL) and others. Proximate analysis indicated moisture (5.06%), total ash (1.22%), crude fat (62%), crude fibre (0.89%), crude protein (23.05%) and total carbohydrate (7.78%). Mineral composition analysis showed the presence of K (320.71 μg/ mL), Na (130.98 μg/mL), Mg (6.45 μg/mL), Ca (8.01 μg/mL), Fe (2.46 μg/mL), Zn (0.62 μg/ mL), Cu (0.69 μg/mL) and Mn (0.2 μg/mL). These results suggest that the seeds of T. pedata could be a good source of supplements to improve cardiovascular health, insulin sensitivity, immunomodulation, anti-inflammation, and antimicrobials. The seeds could also be a source of proteins, fats, and minerals to alleviate malnutrition especially for children under 5 years. Furthermore, since these seeds are rich in oil, they could be used for production of soaps, paints and lubricants.

Authors: Oraekwe Ifeoma Nwanneka
Published: February 2024

Libraries are important centers in education and for resource sharing, so, also librarians’ important personnel in tertiary institutions. In Nigeria, librarians may not be said to have fulfilled those expected roles to the satisfaction of stakeholders. Many factors could be directly and indirectly responsible; however, the current study focused on librarians’ creativity and innovation and the role of organizational climate in the creative process of librarians. Being a survey study, the study utilized correlation design using descriptive statistics and Pearson R statistics to establish the perception of librarians about their organizational climate and the relationship between this perception on their creativity and innovation. The participants were 89 librarians sampled purposively from University librarians in Anambra State. The questionnaires used for data collection was simplified adaptation of Coveney (2008) and Organizational Climate Questionnaire (OCQ) by Litwin and Stringer (1968). The result was indicative that the perception of organizational climate is low among University librarians in Anambra State but the librarians were relatively high on creativity and innovation. Secondly, there was a significant positive correlation between librarians’ perception of organizational climate and creativity and innovation at r(2, 89) = .68, p > .05 implying that favourable climate to employees helps creative process to thrive. It is recommended that stakeholder should increase their support to University librarians in order to motivate them to perform at the highest level bringing their creativity into the equation.

Information technology has undergone tremendous advancement in recent decades. The power brought forward by the developments in information technology (IT) has seen its adoption across all sectors of the economy, with its implementation resulting in unprecedented efficiency. In Nigeria, implementing IT, especially in the education sector, remains one of the library’s objectives to enhance human capacity through access to digitized information. Academic libraries’, being at the forefront of providing information, implementing IT are inevitable and enhances service delivery. However, the implementation of information technology in Nigerian academic libraries has been characterized by numerous challenges affecting their capacity to efficiently deliver services to their users. The established processes for implementing information technology in these institutions include inadequate funds to purchase and maintain IT equipment, power interruptions, low computer literacy among librarians, and poor internet connectivity. Fortunately, adequate staff training and exploring alternative energy sources include some appropriate solutions to the identified challenges.
How food insecurity experience among older adults can provide evidence for an innovative, system-led and culturally-sound social work practice interventions in a communal Ghana
Authors: Asamoah Brilliant
Published: February 2024

As people grow older and lose capacity to maintain activity in securing food for themselves either because of functional disability or financial incapacity, there should be a meso and or macro support services to ensure food security amongst them. In Ghana, evidence show that most older people report food insecurity, necessitating a need for a reflection on how social work professional (with its core mandate) can innovatively and culturally promote food security for older adults in Ghanaian context. Deploying descriptive qualitative analysis, this study presents the qualitative findings of older adults’ experiences of food insecurity across three regions of Ghana. Overarchingly, the analysis identified three major themes related to food insecurity experience recurrent to all or most of the participants. The themes include 1) sources of food items for older adults; 2) perspective on accessibility to food; 3) finances determining older adults’ food accessibility. Results are discussed in relation to existing literature and social work implications. Social work profession in Ghana can adopt innovative and culturally sound approaches, including ‘nnoboa’ in ensuring food security for older adults. The findings contribute to the evidence base for social work, elaborating the in-depth understanding of the experiences of food insecurity in old age.

There is a concern that Manihot esculenta Crantz (Euphorbiaceae) grown in Rivers State, Nigeria may be contaminated with heavy metals due to industrial activities with likely risk to human health. This study determined the heavy metal contents in the soil and tubers of M. esculenta and potential health risks in Wistar rats. Tubers harvested from different farms in Rumuji, Omoku and Gokhana areas of the state with their corresponding soil samples were combined and analyzed for heavy metals such as Pb, Cd, Hg, Cr, As and Ni. The control group rats received normal feed while test groups were fed with 30g of blended tubers from the locations respectively for 28 days. The liver and the kidneys were harvested for histopathological examination. Nickel, Pb, and Cr were present in the three locations while Cd and As were not found in Rumuji and Omoku but were present in Gokhana with a concentration of (0.01 ± 0.00 and 0.01±0.00 mg/kg) respectively. Bioconcentration factor was >1 for Pb and Cr in Rumuji. Liver histopathology showed fatty degeneration while the kidney tissues exhibited occluded Bowman’s capsule space. Heavy metals concentrations were within permissible limits although histological findings indicated some degree of hepatotoxicity and nephrotoxicity.

Edycja zawiera trzy ostatnie uniwersały kasztelana chełmskiego Mikołaja Firleja Broniewskiego, które zostały wydane w latach 1657–1658. Kasztelan chełmski jako senator i tamtejszy urzędnik zwoływał szlachtę ziemi chełmskiej na zjazdy, a zarazem informował ją o aktualnej sytuacji politycznej. W obliczu poważnego zagrożenia zewnętrznego nakazywał okolicznej szlachcie podjęcie przygotowań wojennych i wspominał o działaniach podejmowanych przez sąsiednie województwa.
Sierść tekstu. Relacje transgatunkowe w zoonarratologii
Authors: Rembowska-Płuciennik Magdalena
Published: February 2024

Niniejszy artykuł poświęcony jest zoonarratologii jako odmianie narratologii postklasycznej. Omawia zagadnienia, które wymagają ponownego przemyślenia w kontekście transdyscyplinowego zwrotu ku zwierzętom. Fundamentalne założenia epistemologiczne narratologii są bowiem otwarcie antropocentryczne. Narracja konceptualizowana jest jako kategoria mentalna i językowa zależna od sposobu funkcjonowania ludzkiego umysłu. Różne dyscypliny naukowe stawiają ze swojej perspektywy pytania o możliwość komunikacji ze zwierzęciem jako autonomicznym i odrębnym podmiotem, którego poznanie rodzi się przede wszystkim w interakcji. Wymaga to także nowego podejścia do tak ważnych kategorii narratologicznych jak bohater, empatia, identyfikacja, perspektywa narracyjna. W artykule pokazuję rolę perspektywy drugoosobowej jako narracyjnego narzędzia tematyzowania namysłu nad antropocentryzmem narracji. Fur of the Text. Trans-species Relations in Zoonarratology This article is devoted to zoonarratology as a variant of postclassical narratology. It discusses issues that require rethinking in the context of the transdisciplinary animal turn. The fundamental epistemological assumptions of narratology are openly anthropocentric. Narration is conceptualized as a mental and linguistic category dependent on the way in which the human mind functions. Variety of disciplines pose questions about the possibility of communicating with an animal as an autonomous and separate subject, whose cognition is primarily born through interaction. Thus, it requires a new approach to such important narrative categories as character, empathy, identification, and the narrative perspective. In this article, the author shows the role of the secondperson perspective as a narrative tool for thematizing the reflection on anthropocentrism of the narrative.

The Γ-semihyperring is a generalization of the concepts of a semiring, a semihyperring and a Γ-semiring. The concepts of uniformly strongly (weak) prime Γ-semihyperring and essential extension for the Γ-semihyperring are introduced and studied some important properties in this respect. It is proved that any essential extension of a uniformly strongly prime Γ-semihyperring is a uniformly weak prime Γ-semihyperring. Also strongly prime radical of a Γ-semihyperring is introduced and its characterization is made with the help of a super sp-system. A necessary and sufficient condition for a ideal of Γ-semihyperring to be a right strongly prime ideal is provided with the help of sp-system and super sp-system.

In this paper, we derive some results on semiderivation in σ – prime rings. If (R, σ) is a σ-prime ring with involution σ and char ≠ 2, let d be a nonzero semiderivation with g of R is centralizing, then R is commutative. Further we prove that if d commutes with σ and 0 ≠ I in a σ- Ideal of R such that either [d(x), d(y)] = 0 or d(xy) = d(yx), for all x, y Î I, then R is commutative. Finally, a σ-prime ring with char ≠ 2 possessing a nonzero semiderivation under surjective conditions must be commutative.

The effect of magnetic field on an incompressible (Kuvshiniski – Type) viscoelastic rotating fluid heated and soluted from below is considered. For the case of stationary convection medium permeability and stable solute gradient have destabilizing and stabilizing effect on the thermosolutal convection. Magnetic field and stable solute gradient have stabilizing effect, where as medium permeability has destabilizing effect in absence of rotation and having both stabilizing as well as destabilizing effect in the thermosolutal kuvshiniski viscoelastic rotating fluid. It is also found that rotation, magnetic field and stable solute gradient introduce oscillatory modes in the system, where as in their absence principal of exchange of stabilities is satisfied. Graphs also have been plotted by giving some numerical values to the parameters.
