Beyond the Liberal/Non-Liberal: Reclaiming Secularism in the Palestinian Society
Authors: Aburabia Rawia 
Published: July 2024

Abstract
In August 2019, the local council of Umm al-Fahem, Israel, cancelled a scheduled performance of the known Palestinian rapper Tamer Nafar, claiming that Nafar’s artistic work did not meet with the town’s accepted religious, moral, and social norms. Subsequently, residents of the town and the Association for Civil Rights in Israel, petitioned the Court against the local council’s interference with Nafar’s freedom of artistic expression. Significantly, Nafar was not among the petitioners. The Court concurred with the petitioners, determining that the local council had no authority to interfere with Nafar’s artistic content, and if there was concern regarding detrimental effects on public peace or security, police security should be provided for the event. Despite this ruling from an Israeli court, Nafar refused to perform in Umm al-Fahm. Instead, he accepted an invitation for dialogue with the conservative non-liberal forces within Umm al-Fahm council, a dialogue that resulted in reconciliation. I argue that Nafar’s decision, as a liberal subject to choose dialogue with non-liberal forces in Palestinian society embodies the conceptual foundations of post-secularism, which extend beyond the binary of liberal/non liberal divisions and binaries and pave the way for internal dialogue between religious and secular actors. It constructs a platform for liberal subjects in Palestinian society to be heard in the public Palestinian sphere, providing social and political alternatives to the violent authority of Israeli law.
On the Paley graph of a quadratic character

Published: July 2024

Abstract
Paley graphs form a nice link between the distribution of quadratic residues and graph theory. These graphs possess remarkable properties which make them useful in several branches of mathematics. Classically, for each prime number p we can construct the corresponding Paley graph using quadratic and non-quadratic residues modulo p. Therefore, Paley graphs are naturally associated with the Legendre symbol at p which is a quadratic Dirichlet character of conductor p. In this article, we introduce the generalized Paley graphs. These are graphs that are associated with a general quadratic Dirichlet character. We will then provide some of their basic properties. In particular, we describe their spectrum explicitly. We then use those generalized Paley graphs to construct some new families of Ramanujan graphs. Finally, using special values of L-functions, we provide an effective upper bound for their Cheeger number. As a by-product of our approach, we settle a question raised in [Cramer et al.: The isoperimetric and Kazhdan constants associated to a Paley graph, Involve 9 (2016), 293–306] about the size of this upper bound.

AbstractLet (Fn)n≥0and (Ln)n≥0be the Fibonacci and Lucas sequences, respectively. In this paper we determine all Fibonacci numbers which are mixed concatenations of a Fibonacci and a Lucas numbers. By mixed concatenations ofaandb, we mean the both concatenationsabandbatogether, whereaandbare any two nonnegative integers. So, the mathematical formulation of this problem leads us searching the solutions of two Diophantine equationsFn= 10dFm+LkandFn= 10dLm+Fkin nonnegative integers (n,m,k), whereddenotes the number of digits ofLkandFk, respectively. We use lower bounds for linear forms in logarithms and reduction method in Diophantine approximation to get the results.

Aim:	This	study	was	carried	out	to	make	morphometric	identification	of male	and	female	individuals	of	Karabaş,	Yaşmaklı,	Muskalı,	Kalaça	and	Beyaz genotypes	in	Bursa	Oynarı	pigeons. Materials and Methods:	For	this	purpose,	a	total	of	100	pigeons,	10	females and	10	males,	12-14	months	from	each	genotype,	were	examined. Results:	:	The	Oynar	breed's	average	live	weight	was	determined	to	be 306.27±1.32	g.	Average	body	weights	for	males	and	females,	genotypes, and	gender	x	genotypes	were	discovered	to	be	similar	(p>0.05).	Males	were found	to	have	longer	heads	(p<0.05),	but	there	was	no	statistically	significant difference	between	males	and	females	in	terms	of	other	body	traits	(p>0.05). Different	averages	were	determined	in	the	genotypes	in	terms	of	beak	length, beak	depth,	trunk	length,	body	length,	wing	length,	chest	circumference, chest	depth,	and	tail	length	(p<0.05).	In	general,	the	averages	were	lower	in the	Yaşmaklı	genotype	than	in	other	genotypes,	and	higher	in	the	Beyaz	and Muskalı	genotypes	(p<0.05).	The	interaction	between	gender	and	genotypes was	significant	in	beak	depth	(p<0.001). Conclusion:	As	a	result,	it	was	anticipated	that	the	characteristics	detected	for the	first	time	in	the	Oynar	breed	varieties	would	contribute	to	the	definition of	this	breed.	It	was	also	estimated	that	differences	in	the	body	structures	of the	varieties	may	impact	their	flight	characteristics,	and	the	findings	on	this subject	will	attract	the	attention	of	pigeon	breeders.	Considering	their	body structures,	it	was	determined	that	the	Kalaça,	Muskalı,	and	Beyaz	genotypes may	have	superior	characteristics	in	terms	of	flight	time,	and	the	Yaşmaklı genotype	may	have	superior	characteristics	in	terms	of	flight	speed.

Термодинамическое состояние атмосферы, в том числе мезосферы, определяется ее волновой структурой. Серебристые облака являются хорошим индикатором данных волновых процессов. По фотографиям серебристых облаков в г. Якутске проанализированы некоторые характеристики распространения атмосферных волн. Впервые описан случай наблюдения так называемого мезосферного бора в серебристых облаках над Восточной Сибирью, зарегистрированного синхронно с двух однотипных фотокамер. Высота волнового фронта, определенная триангуляционным методом, составила 79 км. Изучен случай распространения нескольких волн различной длины с пересекающимися направлениями в серебристых облаках 25.07.2018 г. Анализ параметров двух волн, распространяющихся навстречу друг другу, показал, что первая имела длину в среднем 53,5 ± 6,2 км и двигалась на северо-восток со средней фазовой скоростью 98,4 ± 12 м/с. Вторая волна типа гребешков со средней длиной 14,8 ± 1,8 км распространялась на юго-запад со средней фазовой скоростью 61,5 ± 6 м/с. Скорость ветрового дрейфа всей облачности составляла 67 ± 5 м/с в западном направлении. Полученные результаты будут полезны для специалистов в области физики волновых процессов в верхней атмосфере.
The article discusses some characteristics of the propagation of atmospheric waves based on photographic observations of noctilucent clouds in the city of Yakutsk. For the first time, a case of observation of the so-called mesospheric boron in noctilucent clouds over Eastern Siberia, recorded synchronously with two cameras of the same type, has been described. The height of the wave front determined by the triangulation method was 79 km. The case of video recording of the propagation of several waves of different lengths with intersecting directions in noctilucent clouds on July 25, 2018 is analyzed. Analysis of the parameters of two waves propagating towards each other showed that the first has average wavelength of 53.5 ± 6.2 km, average phase velocity of 98.4 ± 12 m/s, and northeast direction. The second wave of the scallop type propagated to the southwest with an average phase velocity of 61.5 ± 6 m/s, its average wavelength was 14.8 ± 1.8 km. The speed of westerly wind drift of all clouds was 67 ± 5 m/s.

Внезапные стратосферные потепления (ВСП) значительно влияют на погоду в тропосфере и на динамику верхних слоев атмосферы. Определение ВСП и их классификация сформулированы достаточно давно, однако о ранних (в ноябре – первой половине декабря) ВСП подробная информация отсутствует. В работе исследовано влияние ранних ВСП на стратосферный полярный вихрь с использованием данных реанализа JRA-55 и MERRA2. ВСП определялись двумя способами: по среднезональным значениям температуры и зональной компоненте ветра с учетом и без климатической составляющей. Реакция полярного вихря на потепление представлена полем геопотенциальной высоты. По данным зондирования на полярных станциях разных континентов проанализирован временной ход приземных температуры и давления во время смещения и расщепления стратосферного полярного вихря при раннем ВСП.
The influence of early sudden stratospheric warming (SSW) on the stratospheric polar vortex is presented. The definition of SSW and their classifications have been formulated for a long time, but detailed information is not available about the early (in November – the first half of December) SSW. The determination of early SSW was carried out in two ways using the zonal averaged values of temperature and zonal wind component with and without the climatic component. The polar vortex's response to warming is represented by the geopotential height field. The study was conducted using JRA-55 and Merra2 reanalysis data. Also, the variation of surface temperature and surface pressure during the displacement and splitting of the stratospheric polar vortex during the early SSW is presented based on sounding data at stations of the polar region of different continents. It is known that the VSP has a significant impact on the weather in the troposphere, including the dynamics of the upper atmosphere.

Published: July 2024

The study analyses the occurrence of Ash Maples (Acer negundo L.) in the town of Tirkšliai, which is located in the municipality of Mažeikiai district. The assessment survey was carried out in September–October 2023. The inventory of the Ash Maples was carried out using a route method, recording the coordinates and the conditions of the sites: area, projection coverage of individuals, level of urbanisation of the ecotope, biotope, assessment of whether or not the area of the site was mown, intensity of use of the area where the site is located. The ontogeny stage shall be assessed on the basis of the vegetative and generative characters of the ash-leaved maples and the height of the trees. The height of the individuals of the Ash Maple was determined visually, in metres, by assessing the entire length of the above-ground part of the tree. In total, 14 sites with ash-leaved maples were identified as well as 10 sites with trees of juvenile age. Most of the sites were found in grassland (64 %), 79 % in roadsides, by intensity of land use the highest number of sites were found in unused land (43 %), 50 % of the sites are not mown. It is therefore evident that the occurrence of big-leaved maple trees is higher in less maintained areas.

This study investigates the impact of the 5C credit analysis principles (Character, Capacity, Capital, Collateral, and Conditions of Economics) on the smoothness of murabahah financing payments at KSPPS BMT ItQan Soreang Unit either simultaneously or partially. Micro, Small, and Medium Enterprises (MSE) often face challenges due to a lack of business capital, despite financial products introduced by institutions like Savings and Loans Cooperatives and KSPPS BMT. Persisting issues in payment smoothness necessitate a comprehensive examination, particularly in credit analysis. This research employs a quantitative approach with logistic regression tests on a sample of 101 respondents using statistical techniques such as regression analiysis, wald test, and omnibus test of model coefficients. This research highlights the importance of applying the 5C credit analysis principles to improve risk management, policy development, operational efficiency, and financial inclusion in murabahah financing at KSPPS BMT ItQan Soreang Unit. Findings from the Omnibus Test of Model Coefficients confirm that the 5C principles collectively impact payment smoothness. Moreover, the Wald test identifies Character, Capacity, and Conditions of Economics as significant contributors to the effectiveness of murabahah financing payments at KSPPS BMT ItQan Soreang Unit. This research highlights the importance of applying the 5C credit analysis principles to improve risk management, policy development, operational efficiency, and financial inclusion in murabahah financing at KSPPS BMT ItQan Soreang Unit.
Hypermethylation of the FOXP3 gene regulates Tregs immunodysregulation in chronic idiopathic thrombocytopenic purpura
Authors: Wang Zengsheng , Lang Tao , Li Yan , Zhang Xiaoyan , Abdur Muhubair , Mao Min 
Published: July 2024

Background: Chronic idiopathic thrombocytopenic purpura (ITP) is an autoimmune disease characterized by a breakdown of immune tolerance; in ITP, the body’s immune system mistakenly attacks and destroys platelets. This study aims to investigate the role and underlying mechanisms of FOXP3 in chronic ITP.
Methods: Flow cytometry was used to detect the proportion of CD4+CD25+FOXP3+ regulatory T cells (Tregs) in CD4+CD25+ T lymphocytes from 20 patients with chronic ITP (CITP), 20 acute ITP (AITP) controls, and 20 healthy individuals.
CD4+CD25+ Treg cells were isolated from peripheral blood of patients with CITP using magnetic beads and then treated with phosphate-buffered saline solution or decitabine (a methylation inhibitor) for 48 h. The levels of interleukin-2 (IL-2), IL-10, and transforming growth factor-beta1 (TGF-β1) in the plasma and CD4+CD25+ Treg cells were assessed by Enzyme-linked-immunosorbent serologic assay and quantitative real-time polymerase chain reaction (qRT-PCR). FOXP3 level was measured by qRT-PCR and Western blot analysis. Methylation-specific PCR (MS-PCR) was adopted to detect the status of FOXP3 methylation.
Results: The number of Treg cells and the contents of IL-2, IL-10, and TGF-β1 decreased in patients with CITP, compared to the AITP control group and normal group. FOXP3 expression was reduced and FOXP3 methylation increased in patients with CITP, compared to the AITP control group and normal group. Hypermethylation of FOXP3 promoter led to decrease in FOXP3 level in Treg cells. Inhibition of FOXP3 promoter hypermethylation promoted the secretion of IL-2, IL-10, and TGF-β1 in Treg cells.
Conclusion: The number of Treg cells in CITP patients decreased, and the hypermethylation of FOXP3 promoter led to reduction of its expression in Treg cells, thus affecting the immune functioning of Treg cells.

Published: July 2024

As part of the study, the influence of yttrium content on the properties of particles during controlled precipitation and after thermal treatment was investigated. Precipitation was carried out at a constant pH of 5 from nitric acid solutions, where the concentration of zirconium was 1 mole/dm3 and the yttrium content ranged from 0 to 30 % based on their oxides. The drying and calcination temperatures of the precipitates were 40 °C and 1000 °C, respectively. It was shown that with a yttrium content of up to 15 %, there was a consistent increase in the average diameter of zirconium hydroxide particles during deposition. When the yttrium concentration was increased to 30 %, the average particle size increased during the first 10 minutes of deposition, followed by a gradual decrease. The largest particle diameter was observed in the specimen with 7 % yttrium. In all cases, the formation of spherical aggregates was observed. With an increasing yttrium content, the boundaries between particles became smoother, and the degree of co-deposition of yttrium during synthesis decreased from 80 % to 60 %. Depending on the yttrium concentration, different modifications of stabilized zirconium dioxide powders were obtained: tetragonal ZrO2 for 2–7 % yttrium, and cubic ZrO2 for 15–30 % yttrium. Therefore, the results obtained during the study can be useful for the development of technology for the production of powdered materials for various applications.
Using Edge Detection Techniques on Aeromagnetic Data to Delineate Structures Controlling Orogenic Gold Deposits in the Sefwi Greenstone Belt, Ghana
Authors: Raju P.V.S. , Boadi Benjamin , Wemegah David Dotse 
Published: July 2024

ABSTRACT
The orogenic-style gold deposits in the Sefwi greenstone belt are associated with quartz veins and occur along shear zones. Edge detection techniques (i.e., analytic signal, vertical, and tilt derivatives) were employed to delineate regional planar fabrics (e.g., shear zones, faults) using aeromagnetic data. The enhancing techniques aided the delineation of NE-SW striking lineaments associated with the Kenyase-Yamfo, Hwidiem, Ketesso, Bibiani, and Afema shear zones in the study area. These shear zones are within the Sefwi belt and at the contact zones between the belt and the adjacent metamorphosed volcano-sedimentary rocks of the Sunyani-Comoé and Kumasi-Afema basins. Low-displacement N-S to NNE-SSW trends which are oblique to the NE-SW shear zones, were also delineated. The local bend and offset along the NE-SW striking faults created by the cross-cutting N-S to NNE-SSW faults serve as favourable trap zones to focus fluids migrating along these shear zones. Fry analysis of known orogenic gold occurrences in the study areas shows that the NE-SW lineaments, with an azimuth of 40°-50°, are predominant in controlling the distribution of deposits. There is also a significant structural control in the N-S to NNE-SSW direction with azimuths 0°-10° and 10°-20°.

Published: July 2024

ABSTRACT
Imported Indonesian coal samples collected from thermal power plants were analyzed using Synchrotron Radiation X-ray Fluorescence (SRXRF). Sixteen inorganic elements As, Ca, Cr, Co, Cu, Fe, K, Mn, Ni, Pb, Rb, Se, Sr, Ti, V, and Zn were quantified. To ascertain the abundance in the analyzed samples compared to Clarke values for world coals, the enrichment factor for each element was measured. The analytical results were interpreted using chemometric techniques, namely Pearson’s correlation analysis, hierarchical cluster analysis, and principal component analysis. This study revealed three principal components contributing to 87.99% of the total variance in the data.
Analysis of the Spectral Contrast between Fossil-bearing and Fossil-depleted Limestone from the Kachchh Region, NW India Using Reflectance and Emittance Spectroscopy Data
Authors: Chaudhuri Swagata , Guha Arindam , Bhaumik Ajoy K. , Pathak Suparn , Baranval Nikhil Kumar 
Published: July 2024

ABSTRACTWe analyzed the reflectance and emittance spectra of representative samples of mega and microfossil-bearing limestones and identified the mineralogical controls, which may have led to the preservation of mega and microfossils in the limestone within the spectral domain of 400-2500 nm and 8000-14000 nm. In this regard, we collected and analyzed the reflectance and emittance spectra of fossil-bearing and fossil-depleted limestone samples using respective reflectance and emittance spectra of their dominant constituent minerals. Reflectance spectra of mega and microfossil-bearing limestones have prominent absorption features diagnostic to iron and clay minerals, while emittance spectra of these rocks confirm the presence of silica in the fossil-bearing limestone samples. Spectral features of iron minerals are identified based on the presence of absorption minima at 480 nm and 900 nm, while clay minerals have features at 2200 nm. Presence of silica was identified with emissivity minima at 9000 nm. Laboratory spectral observations are substantiated by field observation and mineralogical studies. Fossil-depleted limestone samples, on the other hand, are characterized by the absence of iron oxide, clay and silica. Spectral contrast between fossil-bearing and the fossil-depleted limestone have allowed us to infer certain mineralogical controls essential for fossil preservation and the role of iron, clay minerals in preserving fossils is discussed in detail. Further, spectral analysis in visible, near infrared, short wave infrared and thermal infrared electromagnetic domain may provide rapid and non-destructive mineralogical assessment of fossil-bearing and fossil-depleted limestone.
Numerical Texture Analysis on NW Iran Dacite, Basalt, and Tephraphonolite: Implications to Constrain their Petrogenesis
Authors: Modjarrad Monir 
Published: July 2024

ABSTRACT
In this research, our focus has been on the quantitative calculations of the texture of volcanic rocks. For this purpose, the rocks with acidic to basic and ultrabasic combinations were selected, and the shape, size, and spatial distribution (CSD and SDP) of their phenocrysts were investigated. The results showed that in volcanic rocks, the ratio of nucleation to crystal growth (J/G) was several times higher, and crystal growth per time unit (Gt) was higher in rocks with fewer nuclei. It also turns out that to evaluate the magma mixing, CSD pattern analysis can be instrumental. The spatial distribution of grains in the extrusive rocks is clustered to random, probably due to the high degree of overstepping and under-cooling conditions. The mineral clusters may form before the emplacement of the flow, at depth during the residence time before the eruption flow, or throughout the rise and flow. The importance of these results displays that due to the progress of imaging methods and statistical-numerical work on crystals and textures; it is time that all petrologists from all over the world, along with geochemical work, pay attention to these types of studies to provide a complete petrological work.
