Islam, Arabowie i wizerunek kalifów w przekazach "Chronografii" Teofanesa Wyznawcy: Nr XLIII
Authors: Cecota Błażej
Published: August 2023

„Chronografia” Teofanesa Wyznawcy jest z pewnością jednym z najważniejszych źródeł bizantyńskich zawierających informacje na temat historii początków muzułmańskiej państwowości, kalifatu, w bizantyńskim kręgu kulturowym. Praca zawiera wiele bardzo istotnych passusów skupiających się wokół postaci Muhammada, twórcy islamu, muzułmanów, a także osób reprezentujących kalifat, z jego władcami na czele. W kontekście informacji przekazanych przez Teofanesa na temat Proroka starałem się konfrontować je z wynikami współczesnych badań nad początkami islamu. W ten sposób, o ile to możliwe, mogłem spojrzeć na tę narrację z nieco szerszej perspektywy, nie ograniczając się jedynie do wyliczenia oczywistych oskarżeń formułowanych wobec Muhammada przez bizantyńskiego kronikarza. W drugim rozdziale postanowiłem omówić też zagadnienia, w których wierni Allahowi posłużyli Teofanesowi za punkt odniesienia dla opisów wewnętrznej historii cesarstwa bizantyńskiego temat monofizyckiej, syryjskiej i koptyjskiej współpracy z muzułmanami podczas pierwszej inwazji, zagadnienie ikonoklastyczne, czy kwestia muzułmańskich prześladowań chrześcijan. W trzecim rozdziale podjąłem się omówienia w jaki sposób Teofanes sportretował poszczególnych kalifów. Podzieliłem ten materiał zgodnie z obowiązującą obecnie chronologią, zauważyłem jednak te elementy w „Chronografii”, które nie zgadzają się z powszechnie przyjętymi schematami.

Published: August 2023

The dynamics of the physical properties and reserves of humus in saline soils of an arid semi-desert zone is presented. The basis for the research was observational data for 2010-2022. in a typical hilly landscape of the Astrakhan region. A grid of 100 × 100 m was laid. Soil studies were carried out at the grid nodes along the sampling layers. We studied the change in physical properties (soil moisture; salt content according to the amount of dense residue; soil density; filtration coefficient; soil porosity; moisture reserve), humus reserves and salt state of saline soils under desertification. Comparative analysis showed that negative changes have taken place in the study area and it can be stated that the processes of soil degradation and desertification are intensively developing. It has been established that in the soil layer of 0–40 cm there was a significant reduction in soil moisture reserves against the background of an increase in maximum air and soil surface temperatures, as well as changes in the hydrological regime because of the embankment of the territory. Dehumification processes are observed. The most clearly negative trend was revealed for meadow solonchaks. The change in the hydrological regime of the territory because of embankment contributes to an increase in the areas of automorphic soils in the landscape and a reduction in the areas of meadow soils. An increase in the degree of salinity and compaction was recorded for automorphic zonal soils. The physical destruction of the Baer's hills exacerbates the processes of degradation and the development of desertification in such conditions.

Authors: Tonete Marcelino Marcio Adriano , Macedo de Novaes Allan
Published: August 2023

Propósito: Este trabalho busca descrever como a pandemia de Covid-19 esteve presente nas narrativas fúnebres publicadas pela Revista Adventista (periódico centenário de circulação nacional) durante a crise sanitária, influenciando na constituição dessas memórias. Método: O estudo se desenvolveu a partir da análise documental das notas de falecimento publicadas na seção Memória, espaço tradicionalmente dedicado aos obituários. Foram selecionadas apenas as notas de falecimento que mencionavam a Covid-19 como causa mortis. Sendo assim, das 376 divulgadas no período de junho de 2020 a setembro de 2021, 124 se enquadraram nesse critério.   Resultados: Foi possível perceber que a crise sanitária contribuiu para a ampliação da tradição de publicar obituários. Além de aumentar o número de páginas reservado às notas de falecimento, a revista criou um memorial on-line dedicado exclusivamente à memória das vítimas da pandemia. Isso permitiu que as famílias enlutadas pudessem prestar sua homenagem e gravar as memórias de seus entes queridos num contexto de negação do direito ao luto, restrições aos rituais fúnebres e sepultamentos rápidos. Conclusão: O cenário pandêmico parece ter influenciado na constituição das memórias em si, considerando o fato de algumas dessas narrativas obituárias terem destacado atitudes positivas dessas pessoas apesar do cenário caótico. Além disso, a publicação das notas de falecimento das vítimas da pandemia parece ter assumido também o sentido de registro do que foi a própria crise sanitária e seu impacto no adventismo.

Authors: Ismiyatin Kun , Saraswati Widya , Sudarsono Caeleb Fabrizio
Published: August 2023

Background: Dental caries is a very common non-communicablae disease found in all age groups and found in 3.5 billion people in the world. Caries that harm the pulp tissue can be treated by direct or indirect pulp capping. One of the physical properties possessed by pulp capping is the porosity of material. The material most often used for pulp capping treatment of pulp perforations is calcium hydroxide (Ca(OH) 2 ). However, Ca(OH) 2 has a high pH that caused the porosity to be low. High porosity can facilitate cell development and ion exchange. Thus, additional materials with a lower pH are needed to increase porosity such as Epigallocatechin-3-gallate (EGCG). However, the porosity of the combination of EGCG with Ca(OH) 2 is still unclear, so it needs to be researched. Purpose: To explain the differences of Ca(OH) 2 porosity after the addition of EGCG. Methods: This study used a laboratory experimental study with a post test only control group design. This research using 16 samples for each control (Ca(OH) 2 – aquadest) and treatment (Ca(OH) 2 –EGCG) group. Samples from each group were subjected to freeze drying, observed with SEM, analyzed with ImageJ software, and tested with independent T-test. Results: There was a significant difference (p<0.05) in the percentage of porosity between the addition of EGCG to Ca(OH) 2 namely 32,61% compared to Ca(OH) 2 with aquadest namely 23,38%. Conclusion: The porosity of the combination of calcium hydroxide with EGCG has a higher percentage compared to calcium hydroxide with aquadest.

Published: August 2023

Background: Calcium hydroxide (Ca(OH)2) is the gold standar in pulp capping treatment because the biocompatibility and capability to stimulate hard tissue formation and also antibacterial effect. However, this compound has the disadvantage of being easily soluble in saliva which will increase the risk of leakage in the cavity. Another alternative pulp capping material is calcium carbonate from blood clam shells. Blood clam shells contain 98% CaCO3, CaCO3 has low solubility and is difficult to dissolve in water due to the large ions on Ca2+ and CO32- so that the attractive force between these ions is very strong and finally H2O is not able to break down the CaCO3 compound to be dissolved. Purpose: Explained the differences in the solubility of calcium carbonate from blood clam shells and calcium hydroxide as candidates pulp capping materials. Methods: This research is a laboratory experimental study with a pretest-posttest control group design method. The samples consisted of 12 pieces of Ca(OH)2 and CaCO3 then divided into 2 groups and given treatment. Group 1 CaCO3 immersed in 1 day, group 2 Ca(OH)2 immersed in 1 day, group 3 CaCO3 immersed in 7 days, and group 4 Ca(OH)2 immersed in 7 days. Solubility is calculated according to the solubility formula. Data testing with Anova-Welch. Results: There was a significanly difference in the solubility rate between the CaCO3 dan Ca(OH)2 groups immersed for 1 day and 7 days on the Anova-Welch results (p<0.05). Conclusion: The solubility of CaCO3 in blood clam shells is lower than the solubility in Ca(OH)2.)

Introduction: Based on the Banyuwangi Regency Health Office, the DHF incidence rate in Banyuwangi Regency in 2022 has experienced a significant increase of 30.14 per 100,000 inhabitants, previously 5.70. DHF can be affected by environmental factors such as mosquito larvae, rainfall, and house conditions. DHF control efforts can be carried out by mapping dengue vulnerability to formulate an appropriate policy. Conversely, the spatial analysis of DHF cases in Banyuwangi is rarely found. This study aims to analyze spatial factors at DHF IR and the relationship between an environmental factor and DHF IR in Banyuwangi Regency. Methods: This study used an ecological study approach. The data used was secondary data from 2020–2022. Data were obtained from Banyuwangi Regency Health Office and Banyuwangi Regency Central Statistic Agency. Moran's I and LISA determined the spatial autocorrelation. Spatial regression was also used in this study. Results and Discussion: DHF IR Banyuwangi Regency had spatial autocorrelation (p-value=0.0010) with clustered patterns (I=0.4789). The pattern of clustering dengue cases in an area could occur because of a relationship with previous dengue cases. Spatial autocorrelation was not found between DHF IR with LFI (p-value=0.4560), rainfall (p-value=0.0610), CBTS villages (p-value=0.1870), and healthy houses (p=value=0.3680). The independent variable in this study did not have a significant relationship with DHF IR. Conclusion: The average DHF IR in Banyuwangi Regency in 2020–2022 had a grouping pattern related to district proximity. LFI, rainfall, CBTS villages, and healthy houses had no significant relationship with DHF IR.

Objective: to evaluate the possibilities of dynamic scintigraphy for the diagnosis of esophageal dysmotility (ED) and gastroesophageal reflux (GER) in patients with systemic sclerosis (SS).

Material and methods. The study group included 77 patients with established SS of different disease duration (from several months to 30 years) who underwent Technephyt 99mTc dynamic esophageal scintigraphy using two-stage protocol. During the first stage, the esophageal transport function was evaluated; during the second stage, the presence and severity of GER were assessed. Scans were analyzed using visual assessment, quantitative estimation of time/activity curves, and a proposed three-point scale for evaluating ED and GER severity. The control group consisted of 19 practically healthy individuals who underwent a routine examination to exclude digestive system and gastrointestinal tract diseases, the algorithm of which included dynamic scintigraphy.

Results. ED was found in 74 of 77 patients (96%). According to three-point scale, severe ED (3 points) was registrated in 41 (55%) patients, moderate ED (2 points) in 15 (21%), and mild ED in 18 (24%). GER was diagnosed in 35 of 77 cases (45%): mild GER in 13 (37%), moderate GER (2 points) in 22 (63%), and none of the patients was found to have severe GER (3 points). A significant relationship between the presence of GER and the severity of ED was not obtained, but a direct correlation was established between ED and GER severity.

Conclusion. Most SS patients demonstrated ED of varying severity associated with mild and moderate GER in nearly 45% of the cases. The study results confirm the practical significance of dynamic scintigraphy for assessing the esophageal transport function and GER in SS patients.

Published: August 2023

Positron emission tomography combined with computed tomography (PET/CT) with 18F-fluoro-deoxyglucose (18F-FDG) plays an important role in the management of cancer patients and is mainly used for primary staging, evaluation of treatment response and detection of disease recurrence. Due to non-specific nature of 18F-FDG uptake, a radiologist must be familiar with both physiological and atypical distribution of radiopharmaceuticals. Inappropriate patient preparation for the study and/or taking certain drugs can lead to abnormal 18F-FDG distribution. Our clinical case demonstrates an atypical uptake of 18F-FDG in white adipose tissue in a child treated with glucocorticoids for a long time.

(2) Methods: The patient presented with a steadily growing, ulcerating superficial tumor in her left breast. To determine the nature of the tumor, a diagnostic assessment was conducted, which included a positron emission tomography (PET) scan and histological analysis. (3) Results: The diagnostic assessment confirmed the presence of a malignant Grade II superficial infiltrating ductal carcinoma. Following the diagnosis, the patient underwent a modified radical mastectomy under general anesthesia. Subsequently, she received four cycles of adjuvant chemotherapy, followed by taxol administrations. (5) Conclusions: This case report underscores the importance of conducting a thorough examination and maintaining a high index of suspicion for breast tumors. By documenting this case, the report contributes to the existing knowledge on various manifestations of breast cancer and highlights the necessity of early identification and aggressive treatment. This knowledge can be applied to identify and manage similar cases in the future, leading to improved patient outcomes.
The Predicate of the Current Mathematical Knowledge Substantially Increases the Constructive Mathematics What Is Impossible for Any Empirical Science
Authors: Tyszka Apoloniusz
Published: August 2023

This is a shortened and revised version of the article: A. Tyszka, Statements and open problems on decidable sets X⊆N, Pi Mu Epsilon J. 15 (2023), no. 8, 493-504. The main results were presented at the 25th Conference Applications of Logic in Philosophy and the Foundations of Mathematics, see http://applications-of-logic.uni.wroc.pl/XXV-Konferencja-Zastosowania-Logiki-w-Filozofii-i-Podstawach-Matematyki. We assume that the current mathematical knowledge is a finite set of statements which is time-dependent. In every branch of mathematics, the set of all knowable truths is the set of all theorems. This set exists independently of our current scientific knowledge. Nicolas D. Goodman observed in Synthese that epistemic notions increase the understanding of mathematics without changing its content. We explain the distinction between algorithms whose existence is provable in ZFC and constructively defined algorithms which are currently known. By using this distinction, we obtain non-trivial statements on decidable sets X⊆N that belong to constructive mathematics and refer to the current mathematical knowledge on X. This and the next sentence justify the article title. For any empirical science, we can identify the current knowledge with that science because truths from the empirical sciences are not necessary truths but working models of truth from a particular context.

A large number of microplastics (MPs) have been found in various stages of wastewater treatment plants, which may affect the functional microbial activity in activated sludge and lead to unstable pollutant removal performance. In this study, the effects of different concentrations of polylactic acid microplastics (PLA MPs) on system performance, nitrification and phosphorus (P) removal activities, and extracellular polymeric substances (EPS) were evaluated. The results showed that under the same influent conditions, low concentrations (50 particles/(g TS)) of PLA MPs had no significant effect on effluent quality. The average removal efficiencies of chemical oxygen demand, phosphate and ammonia were all above 80%, and the average removal efficiencies of total nitrogen remained above 70%. High concentrations (200 particles/(g TS)) of PLA MPs inhibited the activities of polyphosphate accumulating organisms (PAOs) and nitrifying bacteria. The specific anaerobic P release rate decreased from 37.7 to 23.1 mg P/(g VSS·h), and the specific aerobic P uptake rate also decreased significantly. The specific ammonia oxidation rate decreased from 0.67 to 0.34 mg N/(g VSS·h), while the change in specific nitrite oxidation rate was not significant. The dosing of PLA MPs decreased the total EPS and humic acid content. As the concentration of PLA MPs increased, microbial community diversity increased. The relative abundance of potential PAOs (i.e., Acinetobacter) increased from 0.08% to 12.57%, while the relative abundance of glycogen accumulating organisms (i.e., Competibacter and Defluviicoccus) showed no significant changes, which would lead to improved P removal performance. The relative abundance of denitrifying bacteria (i.e., Pseudomonas) decreased from 95.43% to 58.98%, potentially contributing to the decline in denitrification performance.

A patient in her early 20s presented with constant and progressive lower abdominal and back pain, mainly on the right side of the abdomen, purulent vaginal discharge and pyrexia. Radio-logical assessment revealed a possible tuboovarian abscess and incidental diagnosis of ipsilateral renal agenesis. The patient was treated for pelvic inflammatory disease (PID), however after antibiotic administration and since the symptoms were not resolving, an abdominal MRI was requested which revealed a uterus didelphys with two cervices, an obstructed haemivagina and evidence of haematocolpos. The diagnosis of OHVIRA syndrome was confirmed and the patient underwent an excision of the vaginal septum, drainage of the haematopyocolpos and laparoscopic drainage of the tuboovarian abscess. She achieved a good recovery.

Lactic acid bacteria (LAB) have an extracellular proteolytic system that includes a multi-domain, cell envelope protease (CEP) with a subtilisin homologous protease domain. These CEPs have different proteolytic activities despite having similar protein sequences. Structural characterization has previously been limited to CEP homologs of dairy and human derived LAB strains, excluding CEPs of plant derived LAB strains. CEP structures are a challenge to determine experimentally due to their large size and attachment to the cell envelope. This study aims to clarify the prevalence and structural diversity of CEPs by using the structure prediction software AlphaFold 2. Domain boundaries are clarified based on a comparative analysis of 21 three-dimensional structures, revealing novel domain architectures of CEP homologs that are not necessarily restricted to specific LAB species or ecological niches. The C-terminal flanking region of the protease domain is divided into fibronectin type-III-like domains with various structural traits. The analysis also emphasizes the existence of two distinct domains for cell envelope attachment that are preceded by an intrinsically disordered cell wall spanning domain. The domain variants and their combinations provide CEPs with different stability, proteolytic activity and potentially adhesive properties, making CEPs targets for steering proteolytic activity with relevance for both food development and human health.

Unlike trees, shrubs (i.e., multiple-stemmed woody plants) do not need evenly spaced large diameter structural roots and thus can spread further per unit belowground biomass. We therefore hypothesized that compared to trees, shrubs respond more to asymmetric distributions of nutrients and reach nutrient-rich patches of soil faster and with less below-ground biomass. To test these hypotheses we planted individual seedlings of shrubs (Cornus racemosa, Rhus glabra, and Viburnum dentatum) and trees (Acer rubrum, Betula populifera, and Fraxinus americana) in the centers of sand-filled rectangular boxes. In one direction we created stepwise gradients of increasing soil nutrients with slow-release fertilizer; in the other direction no fertilizer was added. Seedlings were harvested when their first root reached the plexiglass-covered fertilized end of their box; time taken as well as above- and below-ground biomass by nutrient segment were determined. There were no consistent differences between the shrubs and trees in belowground architectural plasticity (= ratio of biomass in fertilized and unfertilized volumes of soil) or in the rate and efficiency of lateral growth. Interspecific variation appeared more related to edaphic characteristics of the native habitats than to growth form. The fastest and most efficient roots were produced by the shrub (R. glabra) and the tree (B. populifolia) that are characteristic of poor soils. Root foraging by R. glabra was also facilitated by rapid rhizomatous expansion. The tested shrubs and trees did not consistently differ in nutrient foraging efficiencies or rates but further study is warranted with larger plants and more species.

Published: August 2023

We investigate the use of amplitude amplification on the gate-based model of quantum computing

as a means for solving combinatorial optimization problems. This study focuses primarily on

QUBO (quadratic unconstrained binary optimization) problems, which are well-suited for qubit superposition states. Specifically, we demonstrate circuit designs which encode QUBOs as ‘cost oracle’

operations UC, which when combined with the standard Grover diffusion operator Us lead to high

probabilities of measurement for states corresponding to the optimal and near optimal solutions. In

order to achieve these probabilities, a single scalar parameter ps is required, which we show can be

found through a variational quantum-classical hybrid approach.
Aortic valve stenosis and cancer: problems of management

Published: August 2023

Aortic valve stenosis and malignancy frequently coexist and share the same risk factors as atherosclerotic disease. Data reporting the prognosis of patients with severe aortic stenosis and cancer are limited. Tailoring the correct and most optimal care for cancer patients with severe aortic stenosis is complex. Cancer patients may be further disadvantaged by aortic stenosis if it interferes with their treatment by increasing the risk associated with oncologic surgery and compounding the risks associated with cardiotoxicity and heart failure (HF). Nowadays, several therapeutic options are available for aortic valve stenosis (surgical valve replacement , transcatheter valve implantation, balloon valvuloplasty, or medical therapy), but in presence of malignancy, the use of one of these versus the others should be decided on a case-by-case approach, depending on cancer stage and associated treatment, expected outcome, comorbidities and after an accurate physical examination and Doppler-echocardiography which are the key tools for diagnosing and evaluating aortic stenosis. The current review considers the available data on the association between aortic stenosis and cancer, and therapeutic options.
Effective and Enduring Electric Vehicle Heat Pump Enhanced by Microchannel Heat Exchanger with Superhydrophobic Surface Treatment

Published: August 2023

Battery-powered electric vehicles (EVs) have emerged as an environmentally friendly and efficient alternative to traditional internal combustion engine vehicles, while their single-charge driving distances under cold conditions are significantly limited due to the high energy consumption of heating systems. Heat pumps can provide an effective heating solution for EVs, but their coefficient of performance (COP) is hampered by heat transfer deterioration due to frost accumulation. This study proposes a solution to this issue by introducing a microchannel heat exchanger (MHE) with superhydrophobic surface treatment (SHST) as a heat pump evaporator. A computational-fluid-dynamics MHE model and a dynamic heat pump model are developed and rigorously validated to examine the detrimental impact of frost accumulation on heat transfer, airflow resistance, and heat pump performance. When the frost layer thickness is 0.8 mm at a given air-side velocity of 1.0 m/s, the air-side heat transfer coefficient can be reduced by about 75%, and the air-side pressure drop sharply increases by 28.4 times. As frost thickness increases from 0 to 0.8 mm, the heating effect drops from 3.97 to 1.82 kW, and the system COP declines from 3.17 to 2.30. Experimental results show that the frost thickness of the MHE with SHST reaches approximately 0.4 mm after 30 minutes, compared to that of 0.8 mm of the MHE without SHST, illustrating the defrosting capability of the superhydrophobic coating. The study concludes by comparing the performance of various heating methods in EVs to highlight the advantages of SHST technology. As compared to traditional heat pumps, the power consumption of the proposed system is reduced by 48.7% due to the defrosting capability of the SHST. Moreover, the single-charge driving distance is extended to 327.27 km, an improvement of 8.99% over the heat pump without SHST.

Published: August 2023

Perfluorohexane sulfonate (PFHxS) is a widely detected replacement for legacy long-chain perfluoroalkyl substances (PFAS) in the environment and human blood samples. Its potential toxicity led to its recent classification as a global regulated persistent organic pollutant. Although animal studies have shown a positive association between PFHxS levels and hepatic steatosis and hepatocellular hypertrophy, the link with liver toxicity, including end-stage liver cancer, remains inconclusive. In this study, we examined the effects of PFHxS on the proliferation of human hepatocellular carcinoma (HCC) cells, Hep3B and SK-Hep1. Cells were exposed to different PFHxS concentrations for 24–48 hr to assess viability and 12–14 days to measure colony formation. Viability of both cell lines increased at PFHxS concentrations <200 μM, decreased at >400 μM, and were highest at 50 μM. Colony formation increased at <300 μM and decreased at 500 μM PFHxS. Consistent with the effect on HCC proliferation, PFHxS increased expression of proliferating cell nuclear antigen (PCNA) and cell-cycle molecules (CDK2, CDK4, cyclin E, and cyclin D1). In summary, PFHxS exhibited a biphasic effect on HCC cell proliferation, promoting survival and proliferation at lower concentrations and being cytotoxic at higher concentrations. This suggests that PFHxS potentially exacerbates HCC progression.
Achieving Zero Efficiency Droop in Highly Efficient N-Polar AlGaN Tunnel Junction-based 254 nm DUV LED

Deep ultraviolet (DUV) light emitting diode (LED) at emission wavelength of 254 nm is inevitable to replace the conventional toxic mercury UV Lamp as demanded by Minamata Convention of 2020. Both the conventional DUV LEDs (C-LED) and tunnel junction (TJ)-based UVC LEDs are suffering from high operating voltages, low hole injection efficiency and efficiency droops. Therefore, p-AlGaN and n-AlGaN layers-based TJ is one of the most promising parts of optical devices and has been widely utilized as carrier tunneling in DUV LEDs to mitigate both the contact resistance for Ohmic contact and low hole injection efficicny at 254 nm emission. Here an approach is presented to electrically manipulate the quantum tunneling probability by exploiting the transported carriers at the interface of n-AlGaN/p-AlGaN TJ with moderate Si and Mg-doping levels and optimized thickness. As a result, the Augur recomination rate was sucesfully suppressed and quite high radiative recombination rates were achived in the 254nm TJ-based DUV LEDs, which is attributed the improved holes injection toward the MQWs when compared to C-LED. The internal-quantum efficiency (IQE) of approximately ~ 88% in the TJ-based LED with zero efficiency droop is achived, which is 1.3 times greater than the IQE of approximately ~ 66% in the C-LED with efficiency droop of 53%. Based on our known knowledge, this is the highest reported IQE (88%) at emission wavelength of 254 nm in the AlGaN TJ-based LED with efficiency droop of 0%. It was found that the light output powers (LOP) of TJ-LED increases linearly under the varying current density, whereas in the case of C-LED the LOP changes nonlinearly under varying current density. This is attributed to the lower Augure recombination rate in the MQWs of TJ-based DUV LED. The operating voltages were remarkable reduced from 20 V to 5.4 V under 200 mA operation, which is attributed to the thickness and doping optimization in TJ and better selection of realively lower Al-content in the contact-layer. The demonstrated TJ-based DUV LEDs opens the door to epitaxial growth of high-performance UV emitters in MOCVD and MBE for a plethora of biomedical applications.
