  • Environmental influence on the built heritage, Saudi Arabia regions

    • Free pre-print version: Loading...

      Abstract: Abstract The main concern of this paper is to explore and analyze the influence of the environment on the built heritage in Saudi Arabia. It is hypothesized that the environment formed and initiated the main features of the built heritage in Saudi Arabia. This influence, in addition, is adapted through different variables such as cultural, natural, and climate, including religion, traditions, geology, location, land nature and soil, and macroclimate and microclimate. These variables, in fact, formed the main features of the built heritages, including pattern, type and character. Other external factors, to some extent, also influenced the architectural elements of the built heritage, especially the interrelationship with other civilizations (Wang et al in Heritage 4:2942–2959. https://doi.org/10.3390/heritage4040164, 2021). The investigation of the environmental variables, therefore, used to define the influence of each variable on the main features of different buildings of the built heritage, particularly houses, and palaces in Saudi Arabia. The analysis, moreover, focused on the shared features of these buildings in the main regions of Saudi Arabia. The purpose is to define that although the climate and the natural variables may differ in Saudi Arabia, the built heritage shares the main urban pattern and architectural features mostly as a result of the influence of the cultural variable, particularly the religion, traditions, and habits. In other words, cultural variables have a direct influence on defining the shared features of the built heritage. Furthermore, the rationale of this analysis is to prove that the built heritage is highly valuable because it was initiated and developed as a part of its environment. It afforded its residents with their religious, traditions, habits, social, and living necessities. Therefore, it requires protection for the future generations in Saudi Arabia (Alnaim MM (2022b) J Archit Plann 34:223–238. https://doi.org/10.33948/JAP-KSU-34-2-5, 2022b; Spahic in A conceptual framework for sustainability in Islamic architecture: the significance of the islamic concepts of man and the environment.

  • Crossed molecular beam studies of bimolecular reactions of atomic oxygen
           with nitrogen-bearing organic molecules (nitriles and N-heterocyclic)

    • Free pre-print version: Loading...

      Abstract: Abstract In this contribution, dedicated to the memory of Prof. Gian Gualberto Volpi, we provide a short review of recent work carried out in our laboratory on reactive scattering studies of the reaction dynamics of atomic oxygen with nitrogen-bearing organic molecules. Specifically, we focus on the polyatomic bimolecular reactions of atomic oxygen, both in the ground and first excited state, O(3P) and O(1D), with the simplest unsaturated nitriles, namely HCCCN (cyanoacetylene) and CH2CHCN (cyanoethylene, or acrylonitrile), and with the simplest six-member ring N-heterocyclic compound, pyridine (C5H5N). Using the crossed molecular beam (CMB) scattering technique with universal electron-impact ionization mass-spectrometric detection and time-of-flight analysis to measure product angular and velocity distributions, the primary product channels and their branching fractions were determined, thus assessing the central role played by intersystem-crossing (ISC) in this class of reactions. The experimental work was synergistically accompanied by theoretical calculations of the relevant triplet and singlet potential energy surfaces (PESs) to assist the interpretation of experimental results and elucidate the reaction mechanism, including extent of ISC. Cyanoacetylene and cyanoethylene are of considerable interest in astrochemistry being ubiquitous (and relatively abundant) in space including comets and the upper atmosphere of Titan. Being oxygen the third most abundant element in space, the title reactions are of considerable relevance in the chemistry of extraterrestrial environments. In addition, they are also important in combustion chemistry, because thermal decomposition of pyrrolic and pyridinic structures present in bound N-containing fuels generates N-bearing compounds including, in particular, the above two nitriles.

  • Exotic species in the Erbario Estense: new plants from the world to
           sixteenth-century Italy

    • Free pre-print version: Loading...

      Abstract: Renaissance herbaria may provide precious information on exotic plants known or even introduced in Italy during the fifteenth and sixteenth centuries AD. In the Erbario Estense, preserved in the Archivio di Stato di Modena (northern Italy), there are 14 species considered as allochthonous neophytes or not present in the Italian flora. First, we accurately verified the taxa identification; then, we searched for the same species in the other coeval Italian Renaissance herbaria and collected the information present in the written sources of the second half of the 1500s (concerning, above all, the use of these species as medicinal plants); finally, we paid attention to their current uses in ethnobotanical tradition and their market value. For 12 taxa, we could confirm the former identification; whereas for 2, we came to a different conclusion; the comparison with other Renaissance herbaria, particularly Aldrovandi’s, greatly helped this evaluation process. The species treated here are not placed according to a precise order nor do they have particular medicinal values in common: probably, the specimens were simply added to the existing nucleus, as the species were known or were proven to be rather useful. We shall be able to gain further knowledge when it shall be possible to study all the remaining species. In any case, the Erbario Estense is an important testimony for sixteenth-century botany, that contains some of the most ancient specimens of exotic species that are of common use in large parts of the world today.

  • An investigation of Earth surface deformation by SBAS-InSAR analysis

    • Free pre-print version: Loading...

      Abstract: Land subsidence, whether in its gradual down-settling form, creeping ground fracturing, or sudden sinkholes, is considered one of Iran's most catastrophic environmental challenges. The present study employed interferometric synthetic-aperture radar (InSAR) to detect land displacement in Garmsar City. The output maps reveal significant subsidence at 30 cm year−1 rates. According to the correlated subsidence map and piezometer data, groundwater harvesting for urban, industrial, and agricultural uses is primarily responsible for subsidence. High dependence on underground water resources and the absence of surface water resources in Iran's central regions have led to a radical decline in groundwater heads. For this target, 17 frames of images during 2015–2019 with a small temporal-perpendicular baseline were allocated and analyzed using the small baseline subset (SBAS). After removing unnecessary phases and noise, phase shift due to land deformation was extracted and converted to surface displacement. The InSAR analysis revealed a maximum of 37 cm and at least 33 cm subsidence for the Garmsar plain, and the average annual subsidence is estimated to be 36 cm, which is very close to the subsidence rate of the Tehran and Varamin plains. High-subsidence areas were generally located in the northern part of the Garmsar Plain, and subsidence rates decreased in the Southeast. The temporal and regional relationships between groundwater data and subsidence suggest that the general pattern of subsidence in the Garmsar Plain is caused by groundwater overexploitation, leading to widespread surface deformation. Since Garmsar is close to the capital, water resources are under pressure. By managing water resources in this area, this phenomenon will be reduced. Graphical abstract

  • Diversity profiles of moths in relation to island characteristics in two
           archipelagos of the Mediterranean Sea

    • Free pre-print version: Loading...

      Abstract: Abstract Diversity profiles of macromoth faunas in relation to island characteristics were studied at eight islets offshore Sardinia (one of the main Mediterranean islands) belonging to two distinct archipelagos which are included in two protected areas: Arcipelago di La Maddalena National Park and Marine Protected Area Tavolara-Punta Coda Cavallo. Night-flying macrolepidoptera were sampled using light traps with fluorescent tube, and their abundances per islet analysed through a suite of statistical tools. Overall, a total of 189 species were recorded across the various islands: 82 Noctuidae, 27 Erebidae, 1 Euteliidae, 2 Nolidae, 71 Geometridae, 5 Sphingidae and 1 Drepanidae. Neither area nor distance from Sardinia influenced the diversity profiles on each island, whereas a species–area relationship was clearly observed. Diversity profiles were comparable across islands, with Figarolo showing the highest evenness and Caprera the lowest one. Also, dominance, Simpson’s, Shannon’s and Chao’s estimates were not correlated with island area or distance from Sardinia. Management implications for the studied insular moth communities and habitats are provided.

  • A semi-empirical model for thermal decomposition of carbonates and its
           application to astrobiology

    • Free pre-print version: Loading...

      Abstract: We review the basis of a semi-empirical model of carbonate decomposition developed by the authors, shortly discussing numerous previous theories. Then, the model is applied to the modeling of a scenario of matter transport from space to the surface of planets embedded into sub-mm mineral grains, with the correction of the so-called additional enthalpy, coming from the experiments. Having magnesium and calcium carbonates as mineral phases and the atmosphere of Earth and Mars as environments, the chemical-physical history of grains entering at different angles and speeds is discussed. The results are compared with those obtained previously and new evaluations of the most promising scenarios are formulated. Graphical abstract

           Solanum villosum Mill. leaf and berry extracts

    • Free pre-print version: Loading...

      Abstract: Abstract The present work depicted the pharmacological and nutritional importance of Solanum villosum Mill. based on its traditional value. It is an ethnomedicinal plant of the family Solanaceae used to treat edema and sore eyes, apart from its use as salad and fruit. Leaves and berries of Solanum villosum were explored for the bioactive compounds, antioxidant activity and nutritional potential. Plant extract of both parts i.e., leaves and berries were prepared in methanol and chloroform solvent, then subjected to analysis. Alkaloids, flavonoids, phenols, saponins, and tannins were quantified as major phytochemicals. Antioxidant activity was tested by DPPH radical scavenging, Phosphomolybdate and reducing power assay. Brine shrimp lethality assay was employed to study cytotoxic activity of extracts. Assessment of nutritional value was done by proximate analysis. Alkaloids and saponins were present in significant quantities i.e., 7.6 mg g−1, 3.48 mg g−1, 5.67 mg g−1, and 1.98 mg g−1 in leaves and berries respectively. Methanol extracts exhibited noticeable antioxidant activity, as compared to chloroform extracts. Higher antioxidant activity of leaves was reported as compared to berries with IC50 values of 196.86 µg mL−1 by Phosphomolybdate assay. Methanol extract of leaves demonstrated promising cytotoxic activity with LD50 value of 74.44 μg mL−1. Results for nutritional analysis indicated presence of carbohydrates, proteins, and crude fiber in both extracts, while protein content was higher in berries. Results of the study suggest that the plant can be utilized as a source of balanced nutraceutical products having benefits of food and medicine.

  • Effect of biochar on some soil properties after 4-year application and its
           effect on growth, yield and nutrient uptake of wheat grown on an alkaline
           soil

    • Free pre-print version: Loading...

      Abstract: This study investigated the impact of biochars on some soil properties, plant growth, nutrient concentrations and uptakes after a 4-year application. Biochars produced at pyrolysis temperatures of 300, 500, and 700 °C were applied to the microplots at a rate of 30 t ha−1 in 2017. In 2020–2021 growing season, basal fertilizations were applied to the microplots before sowing wheat. The results showed that biochar applications had no significant effect on soil pH, EC, and CaCO3, although they increased cation exchange capacity and organic matter content. Available nutrient concentrations were not affected positively in general. While biochar applications enhanced vegetative growth and the straw yield, the grain yield decreased. Moreover, straw and grain nutrient concentrations did not vary with biochar applications, but the total nutrient uptake increased. Positive correlations were determined between the carbon sequestration potential of the soils and total yield. In addition, it was revealed that the effect of biochar applications on soil physical properties did not create a significant variation. According to the principal component analysis, the properties with the lowest effect were found to be EC of the soils. Findings from this study indicated that biochar did not directly affect plant growth by providing nutrients to the soil or increasing the amount of available nutrients; however, it can stimulate plant growth by improving some soil characteristics.

  • Scattering of diatomic molecules from graphite

    • Free pre-print version: Loading...

      Abstract: In the last years, state-to-state molecular dynamics simulations of some basic elementary processes, occurring at the gas–surface interface in a wide range of temperatures and collision energies, have been performed by adopting new potential energy surfaces. In this contribution, our attention is mostly addressed to the role of long-range forces, determining the physisorption of gaseous molecules on the surface. Such forces, formulated in terms of the improved Lennard–Jones interaction potential model, control the formation of precursor or pre-reactive state that plays a crucial role in the dynamical evolution of molecules impinging on the surface in the range of low–intermediate collision kinetic energies. The study focuses on the collisions of H2, O2, N2 and CO, initially in their ground and excited vibro-rotational levels, on a graphite surface. The resulting dispersion coefficients, which control the capture of impinging molecules, are compared and found in good agreement with those available in the literature. New selectivity and peculiarities of scattered molecules, crucial to control the kinetics of elementary chemical processes occurring at the gas–surface interfaces under thermal and sub-thermal conditions, of interest in different applied fields, are highlighted.

  • Antioxidant and antimicrobial analyses of Ficus palmata and Calotropis
           procera extracts and their phytochemical screening

    • Free pre-print version: Loading...

      Abstract: Ficus palmata Forssk (Moraceae) and Calotropis procera (Aiton) Dryand (Asclepidaceae) are medicinally important plants. Traditionally, Ficus palmata Forssk is well known to cure gastric and diabetic problems. Both plants are found useful in the treatment of cancerous complications and skin eruptions. The present study was aimed to assess bioactivities of selected plants. Cytotoxicity (brine shrimp lethality assay), antioxidant (ABTS, DPPH, phosphomolybdate and reducing power assay), antimicrobial (disc diffusion method) and phytochemical screening was performed to analyze their activities. Crude extract of leaves and fruit of both plants was prepared in two polar solvents, i.e. methanol and chloroform. Significant cytotoxic potential was shown by fruit of both plants with LD50 values of 80.34 and 93.83 µg/mL by Calotropis procera (Aiton) Dryand methanolic extract and F. palmata chloroform extract, respectively. Methanol extracts of leaves of both plants revealed significant antioxidant, antibacterial and antifungal activity. F. palmata leaves methanol extract showed strong antioxidant activity among the tested samples and the LC50 values were 10.39, 14.63 and 19.28 µg/mL in phosphomolybdate, ABTS and DPPH assays, respectively. Promising microbial growth inhibition was observed at 25 µg/mL. The observed bioactivities are consistent with the presence of valuable phytochemicals: alkaloids, flavonoids, tannins, glycosides and saponins. Due to the strong antibacterial, cytotoxic and antioxidant potential endowed by selected plant extracts, these are supposed to be potential candidates for biopharmaceutical and nutraceutical industries. Further work explicating the structural details and isolation of phytochemicals from selected plant species would be recommended. Graphical abstract

  • Disentangling the solar activity–solar wind predictive causality at
           Space Climate scales

    • Free pre-print version: Loading...

      Abstract: Abstract The variability in the magnetic activity of the Sun is the main source of the observed changes in the plasma and electromagnetic environments within the heliosphere. The primary way in which solar activity affects the Earth’s environment is via the solar wind and its transients. However, the relationship between solar activity and solar wind is not the same at the Space Weather and Space Climate time scales. In this work, we investigate this relationship exploiting five solar cycles data of Ca II K index and solar wind parameters, by taking advantage of the Hilbert–Huang Transform, which allows to separate the contribution at the different time scales. By filtering out the high-frequency components and looking at decennial time scales, we confirm the presence of a delayed response of solar wind to Ca II K index variations, with a time lag of \(\sim\) 3.1-year for the speed and \(\sim\) 3.4-year for the dynamic pressure. To assess the results in a stronger framework, we make use of a Transfer Entropy approach to investigate the information flow between the quantities and to test the causality of the relation. The time lag results from the latter are consistent with the cross-correlation ones, pointing out the presence of a statistical significant information flow from Ca II K index to solar wind dynamic pressure that peaks at time lag of 3.6-year. Such a result could be of relevance to build up a predictive model in a Space Climate context.

  • A brief history of physical oceanography with Mediterranean examples

    • Free pre-print version: Loading...

      Abstract: Abstract Oceanography, or Oceanology, is a very broad name covering all the traditional sciences (physics, chemistry, biology etc.) which can be studied in the ocean context. Hence the distinction must be made using the specific names of Physical, Chemical or Biological Oceanography. This particular review is devoted to the history of Physical Oceanography, a discipline which remained at the empirical stage until roughly the middle of last century, with a slow development of the rigorous, mathematical approach and analysis required to fully understand the processes and dynamics at all space/time scales. This review wants to introduce the uninformed reader to this relatively new science, providing a concise but hopefully comprehensive outline of the milestones of its history, from the adventurous beginnings of the past centuries, to the successive, very recent theoretical and observational advances. In this progress, the scientific “giants” who made possible these advances are also presented. Their choice constitutes not only the author’s personal opinion but that of the oceanographic community at large which recognizes their crucial impact in making physical oceanography the quantitative, exact science of today. It is the author’s privilege to have personally known most of them, not only as teachers but as mentors and friends.

    • Free pre-print version: Loading...

      Abstract: Abstract The study aimed to develop and analyze a conjugated zinc Nano particle formulation that would enhance its anti-cirrhosis activity by increasing its bioavailability and release. Standard characterization procedures were used to create and analyze zinc nano particles (ZNPs). Drug release and hepatic cirrhosis model testing were conducted on rats utilizing the enhanced formulation. For 30 days, ZnNPs were supplied through oral gavage. For biochemical examination of serum samples, rats were anesthetized and slaughtered after the research. The expression of genes and microRNAs (miRNAs) in liver tissues was studied; together with expression of liver specific genes and inflammatory markers. These findings were also validated by liver tissue histological and immune histochemical (IHC) studies. Measuring techniques demonstrated the practical synthesis and conjugation of ZnNPs. Nanohybrid ZnNPs showed significant anticirrhosis therapeutic activity. ZnNPs' anti-cirrhosis properties decrease TGFR1 and COL3A1 expression, because they enhance the production of miRNAs that protect against cirrhosis. Furthermore, the expression of cancer markers (AFP, p53) was down/up-regulated in ZnNPs treated groups. Similarly, the pro- and anti-inflammatory markers expressions were found normalized in ZnNPs groups compared to untreated groups. These results were further validated by histopathology and IHC analysis, which showed that ZnNPs have anti-fibrotic properties. We finally, conclude that the that we achieve loading capacity of 94%, 36.63%, respectively, in the successful synthesis of ZnNPs. Furthermore, ZnNPs exhibits in vivo hepato-protective activity by down-regulating hepatic cancer markers and upregulating hepatic functional markers which assure the use of ZnNPs for the treatment of liver cirrhosis in future studies.

      Abstract: Abstract For the synthesis of organic@inorganic hybrid nanoflowers (hNFS), instead of expensive biomolecules such as DNA, enzyme, and protein, the Cucumis sativus (cucumber) leaf extract was used as an organic component in this study. In the PBS buffer with different pH (5, 7.4, and 9), hNFs were synthesized using extract with different volumes, but these parameters (concentration and pH) significantly affected the morphological characteristics of hNFs. Morphologies, elemental compositions, and organic groups that play key role in the synthesis of hNFs were detailed using FE-SEM, EDX, and FT-IR analyses, respectively. hNFs with ideal flower morphology (synthesized at pH 7.4 with 1 ml extract) showed antimicrobial activity against Staphylococcus aureus and Escherichia coli strains. Antimicrobial activity against strains and peroxidase-like activity against guaiacol of hNFs are explained by Fenton mechanisms.

      Abstract: Abstract The pressure on the lands has increased with the dramatic increase in the world population in the last century. Erosion which is a natural process has become a serious artificial concern with this growing pressure. Especially, most of the farmlands in Turkey are particularly affected by erosion. In the current study, it is aimed to determine erosion risk index classes and generate their maps using F-AHP and ANN approaches applied for the estimate of soil erosion risk index (ERI). In addition, these approaches were associated with GIS and geostatistical techniques based on seven soil erosion indicators in Sinop Province including humid and sub-humid coastal environmental ecosystems in the central Black Sea Region of Turkey. In this research, vegetation cover, land use, soil depth, erosivity (precipitation), erodibility (USLE-K), slope (%), and parent material/geology were used as input data by taking into consideration of several literature reviews. According to study results, index values of ERIF-AHP and ERIANN classes were determined quite close to each other. The soil erosion risk index for Sinop province in Turkey indicates that less than 35% of the study area has a low and very low erosion risk area (34.3%), 32.4% is of moderate soil erosion risk area and about 33.2% of the area has high and very high erosion risk when based on F-AHP method. In addition, as for ERIANN, high and very high erosion risk classes made up 30.9% of the total area, while low- and very-low-risk classes made up 37.3%.

  • Quantum chemistry and metadynamics study of kinetic routes to alanine
           formation by CO or CO2 insertions in E- or Z-ethanimine isomers

      Abstract: Abstract Investigations of the synthesis of amino acids are crucial to the understanding of the chemical evolution of life and are of applied interest in biochemistry and pharmaceutical industry. Focus is here on extending the comprehension of their formation, studying by theoretical and computational procedures potential pathways for the synthesis of precursors of alanine. Amino acid is second in simplicity only to glycine and the simplest exhibiting chirality. Eight reaction paths were designed based on known experimental features and on theoretical grounds. For their study, stationary and dynamical quantum mechanical methods were used. For the first set of four reactions examined, E-ethanimine and Z-ethanimine reacted with carbon monoxide forming R- and S-alanine precursors, each process considered as evolving upon two planes of approach. For the other set of four reactions, the ethanimine isomers reacted with carbon dioxide. For all reactions, the chirality of the alanine precursors was also analyzed. Calculations of geometries and energies of the stationary points (reactants, products, van der Waals complexes and transition states) for all reactions were processed, as well as their thermodynamical state functions. The Z-ethanimine and CO reactions were found to be favored. Preferential channels for the chiral center formation were not identified. Biased first-principle molecular dynamics simulations (metadynamics) were carried out to provide the enantiomeric control of the reactions and the formation of other possible remarkable structures: initially 80 metadynamics simulations were performed. They confirmed the precursors of alanine found in the static calculations, but also found additional ones. In general, the last steps of the simulation culminated in simpler and less reactive substances. Our results individuated feasible reaction pathways to precursors of alanine synthesis, although no evidence was obtained of favoring homochiral selectivity. However, insertion of CO and CO2 into ethanimines was considered, with these molecules being of primordial interest, and both were shown to be orientable in gaseous flow, so arguably relevant to the emergence of chirality by a stereodynamic mechanism.

  • Nutrient accumulation potential and nutritional value of some emergent
           macrophytes for restoration of eutrophic water bodies in Greater Cairo,
           Egypt

      Abstract: The current work evaluates the sequestration efficiency of five aquatic macrophytes for inorganic and organic nutrients in their biomass to restore eutrophic wetlands, besides their nutritive quality as animal fodder. Plant, water, and sediment samples were collected from two watercourses (Ismailia canal and Nahia drain) supporting the growth of each of five aquatic plants (Cyperus articulatus, Cyperus alopecuroides, Mentha longifolia, Typha domingensis, and Vossia cuspidata) for chemical analysis. Cyperus articulatus produced the highest biomass (1727.7 g m−2), while M. longifolia had the lowest (115.3 g m−2). The highest levels of N and P (19.20 and 13.20 mg g−1, respectively) were recorded in T. domingensis shoots, while the highest Mg and Na (14.30 and 0.19 mg g−1) were in its belowground tissues. Additionally, M. longifolia shoots had the highest concentrations of K and Ca (0.29 and 17.40 mg g−1). Cyperus articulatus had the highest carbohydrate content, but the lowest crude fiber (CF) and total protein (TP) in its belowground and aboveground tissues, respectively. Menth longifolia's shoot had the highest TP and lowest ash content, while its root had the highest ether extract (EE) concentration. Moreover, the root of T. domingensis had the highest ash content, while its shoot had the highest CF and the lowest nitrogen-free extract (NFE). The five aquatic plants can sequester large amounts of nutrients compared with other similar species. However, T. domingensis is the best plant for extracting most nutrients to restore eutrophic watercourses because it has the highest potential to store nutrients in its aboveground tissues per unit area. Moreover, the nutritional value of the aboveground parts of the five studied species lies within the range of sheep, goat, dairy cattle, and beef cattle forage quality. Graphical abstract

  • Organization scale of photospheric magnetic imbalance in coronal holes

    • Free pre-print version: Loading...

      Abstract: Abstract To investigate the statistical properties of the photospheric magnetic fields underlying coronal holes (CHs) and “normal” coronal regions a classical technique, the signed measure, is used. This technique allows to characterize the scaling behavior and the topology of sign-oscillating magnetic structures in selected regions of line of sigth (LoS) magnetograms recorded by the Heliosismic Magnetic Imager on board of the Solar Dynamic Observatory (SDO/HMI). To this end we have compared the properties of the photospheric magnetic field underlying 60 CHs and 60 non-coronal holes (NCHs). In particular, in addition to having studied distributions and momenta of photospheric magnetic fields associated to the selected regions, we have performed the sign singularity analysis computing the cancellation functions of the highly fluctuating photospheric magnetic fields. We have found that photospheric magnetic fields associated to CHs are imbalanced in the sign and that this imbalance emerges mainly at the supergranular scales.
