- Characterization and biodegradation of paracetamol by biomass of Bacillus
licheniformis strain PPY-2 isolated from wastewater-
Free pre-print version: Loading...
Abstract: Industrialization leads to the entry of diverse xenobiotic compounds into the environment. One such compound is paracetamol (APAP), which is emerging as a pharmaceutical and personal care pollutant (PPCP). In this study, the APAP degrading bacterium was isolated by enrichment culture method from the sewage sample. The microscopy, biochemical, and 16S rRNA gene sequence analyzed the isolate PPY-2, which belongs to Bacillus licheniformis, and GenBank assigned accession number MN744328. Physiological and batch culture degradation studies have indicated that the strain involved in the degradation of APAP. The optimum pH for degradation of the PPY-2 was 7.7, whereas the temperature was 25 °C, agitation speed was 142 rpm, and concentration of APAP was 621 mg/L reported, and the optimum temperatures were 42 °C and 32 °C, respectively. Biomass kinetic was studied at optimal physical conditions, which suggested that the specific growth rate (μ) was 721 mg/L. The GC–MS chromatogram peaks have detected metabolites, viz., oxalic acid, 2-isopropyl-5-methyl cyclohexanone, and phenothiazine. The study confirmed that Bacillus licheniformis strain PPY-2 exhibits metabolic potential to biodegradation APAP and can be further deployed in bioremediation.

- Relevant but neglected habitat types by the Directive 92/43 EEC in
southern Italy-
Free pre-print version: Loading...
Abstract: The 92/43/EEC Habitats Directive is the main European Union legal tool concerning nature conservation. The habitat types listed in Annex I to the Directive are phytosociology-based. It is widely acknowledged that phytosociological analysis is a crucial approach for habitats characterization and for monitoring their conservation status. Based on bibliographic investigations and new field survey campaigns, a list of habitat types neglected by the Habitats Directive is here presented and described for southern Italy. In this paper, 8 new habitat types and 13 subtypes are proposed. For each of these proposed new habitat types, a wide range of information, including ecology, chorology, species composition, syntaxonomy, threats, and conservation status, is here provided. To supply more detailed phytogeographical and coenological information about the proposed new habitat types, distribution maps based on 10 × 10 km reference grids and phytosociological tables including unpublished relevés were carried out.

- Novel implementation of the INFN-CHNet X-ray fluorescence scanner for the
study of ancient photographs, archaeological pottery, and rock art-
Free pre-print version: Loading...
Abstract: INFN-CHNet is the cultural heritage network of the Italian National Institute of Nuclear Physics (INFN) and is constituted by units from Italy and from outside Europe, one of them at Universidad Nacional de San Martín (UNSAM) in Buenos Aires, Argentina. As a result of the initiative carried out during 2015 by the Accademia dei Lincei for the year of the Italian culture in Latin America, an INFN-CHNet laboratory was set at CEPyA-UNSAM with the collaboration of INFN and the Restoration Workshop Centro Tarea. Noteworthy, this laboratory is conceived as a multidisciplinary research facility with complementary skills, both scientific and humanistic. In this context, the first instrument jointly set up, optimised, and applied to Cultural Heritage was an X-ray fluorescence scanner. In this manuscript, we describe the instrument and its main features together with a set of representative yet novel applications in the field of cultural heritage, namely, the experimental study of hidden rock art through laboratory replicas that imitates the problems found in the archaeological sites (hematite drawings hidden below carbon deposition); the study and chemical characterisation of archaeological decorated pottery; and finally, the application of the XRF scanner to ancient photography, for quick and accurate identification of materials and techniques employed. Beyond these specific results, the primary output of this initiative has been the conception of a future network of scientific laboratories in South America, coordinated by CEPyA at UNSAM.

- Effect of chilling and salinity stress on photosynthetic performance and
ultrastructure of chloroplast in faba beans (Vicia faba L.) leaves-
Free pre-print version: Loading...
Abstract: Chilling (Ch) and salinity (S) are challenging stresses affecting plant physiology, growth, and productivity. The current study investigated the effects of these two stresses, singly and in combination, on photosynthetic performance and ultrastructure of chloroplast of faba beans (Vicia faba L. Cv. Aspani). Plants were exposed to 3 °C and 120 mM NaCl for 16 h in an optimized soil mixture (sand:clay 2:1) under optimized conditions. Results showed that both Ch and S significantly reduced photosynthetic rates, Fv/Fm, chlorophyll content, stomatal index, and stomatal conductance. Chilling caused changes in chloroplast ultrastructure (swelling, ruptured envelopes, and shrunk lamellae), while salinity caused more deformation of the thylakoid membrane and disorganization of the grana structure. However, there was an antagonistic effect between Ch x S. The tolerance of plant to 120 mM NaCl, in the present study, was improved by exposure to Ch which rather allowed the maintenance of chloroplast ultrastructure and morphology of stomata. Moreover, using SEM and TEM gave an effective insight of the ultrastructural damage in plant cells under stress and helps to consider the underlying mechanisms of stress effects. Our results suggest that Ch mitigates the noxious effect of S on the photosynthetic performance of Vicia faba plants.

- Climatic, bioclimatic, and pedological influences on the vegetation
classification of "Bosco dell'Incoronata" in Southern Italy-
Free pre-print version: Loading...
Abstract: The ongoing growth of human populations over the past 100 years has led to the widespread degradation of natural ecosystems triggering global environmental, economic, and social problems. Therefore, it is necessary to characterise the priority areas for nature conservation to prevent the loss of ecosystem services and to identify suitable conservation and protection plans. In light of this, the present study aims to identify an operational methodology to characterise the aspects that most influence the highly natural areas, such as those of the Natura 2000 network. Various factors that can influence the vegetation will be considered to identify the best practices to save the naturalness of these ecosystems and habitats. The study area is the forestland “Bosco dell’Incoronata” (Puglia Region, Southern Italy) within the homonymous Natural Regional Park, representing a green island surrounded by cultivated fields. This area was chosen because intense pilgrimages of people for religious purposes are frequent and, therefore, several disturbance factors can be considered. The methodological approach is based on the phytosociological, bio-climatological, and pedological studies, considered essential for an in-depth understanding of the dynamics taking place in the area. The results of the elaborations explain the presence of some of the plant communities found in the area. Finally, some measures are proposed to optimise the conservation strategy and safeguard biodiversity while allowing the use of the area by a man with a more sustainable use of available resources.

- Effects of climate variability and aridity index on wheat yield in
contrasting environments of Iran-
Free pre-print version: Loading...
Abstract: Climate change is one of the challenges that humanity is facing and can have different effects on agricultural production. The effect of climate change is mainly related to the three factors namely increasing carbon dioxide concentration, rising temperature, and changing rainfall patterns. The present study investigated the relationship between grain yield of rainfed and irrigated wheat (Triticum aestivum L.) with climatic variables including minimum and maximum temperature and rainfall in different counties of Tehran, Alborz, Golestan, Kermanshah, and Fars provinces. The drought index (AI) was also calculated to quantify the drought phenomenon. Also, the relationship between drought index and grain yield of rainfed and irrigated wheat was calculated in annual and seasonal dimensions. The results showed that Gorgan (2306.8 kg ha−1) and Larestan (559.3 kg ha−1) have a higher and lower potential for rainfed wheat production compared with other studied areas, respectively. Also, based on the results of the drought index, the climate of Lamerd, Larestan, and Ravansar counties has become drier in the period 1995–2015 and the climate of Karaj has become wetter. The results showed that winter compared with other seasons had the highest drought trend during the studied years. The relationship between rainfed wheat yield and climatic variables in seasonal scale showed that temperature and rainfall in winter and spring had a greater effect on rainfed wheat grain yield in the study areas than other seasons. The relationship between AI and rainfed wheat grain yield showed that areas such as Gorgan, Karaj, and Larestan with increasing drought index value, rainfed wheat grain yield increased. Unlike rainfed wheat, Marvdasht county had the highest potential for irrigated wheat production compared with other areas with the averages of 4481 kg ha−1, while Lamerd had yield of less than 2.7 tons ha−1. The correlation between grain yield and climate variables on seasonal scale showed that the role of temperature was greater than rainfall in irrigated wheat agro-ecosystems. Also, significant correlations between yield and temperature were more in winter and spring seasons than in summer and fall seasons.

methanolic extract-
Free pre-print version: Loading...
Abstract: This study looked at the anticancer, antimicrobial, and antioxidant properties of a methanolic extract of Micractinium reisseri. In vitro antitumor activity of M. reisseri methanolic extract revealed an inhibitory effect against MCF-7 and HCT-116 (breast carcinoma and colon carcinoma) cell lines. Antimicrobial activity of M. reisseri methanolic extract was estimated against Gram-negative bacteria (Pseudomonas aeruginosa RCMB 010,049 and Escherichia coli RCMB 010,052), Gram-positive bacteria (Streptococcus pneumonia RCMB 010,010 and Bacillus subtilis RCMB 010,067) and fungi (Aspergillus fumigatus RCMB 02,568 and Candida albicans RCMB 05,036). The extract showed promising results against all the tested microbes except C. albicans which gave negative results. The algal extract showed 2,2-diphenyl-1-picrylhydrazyl (DPPH), ferric reducing and hydroxyl radical scavenging activity in a concentration-dependent manner with maximum scavenging activity at concentrations (0.001, 0.001, and 5 mg/ml) for each assay, respectively. High-performance liquid chromatography (HPLC) revealed that the active compounds are phenols, alkaloids, and flavonoids. In conclusion, M. reisseri methanolic extract exhibited effective anticancer, antimicrobial, and antioxidant activities.

- Cannibalism, self-cannibalism and autotomy in the non-indigenous
nudibranch Godiva quadricolor-
Free pre-print version: Loading...
Abstract: Biotic conflict can create evolutionary competition across species in the quest to maintain vital populations. In some cases, this process is driven by conflict among members of the same species, an important selective force in high-density non-indigenous populations. By killing and feeding on their intraspecific competitors, cannibals enhance their chance of survival. Here, we report that the nudibranch Godiva quadricolor (Barnard, 1927) from invasive Mediterranean populations expresses a strong propensity to cannibalism as well as cerata autotomy, a likely antipredatory behaviour. In addition, fourteen cases of self-cannibalistic behaviour during captivity have been recorded, one of the most conspicuous records of this uncommon behaviour up to date. We discuss our observations in the framework of the behavioural traits characterizing non-indigenous populations and biological invasions.

Free pre-print version: Loading...
Abstract: Quasiperiodic ornamental patterns represent only a small percentage of patterns when compared to the entire body of periodic patterns. Decagonal pattern is known since twelfth century Iran and fourteenth century western Islam (Andalusia and Morocco). A rich spectrum of octagonal patterns exists at the latter localities (fourteenth century and later), whereas a sole example of a dodecagonal pattern comes from Morocco. Later copies exist in all these regions. My most recent studies were concentrated upon the Andalusian and Moroccan regions, in which the fourteenth century (and later) wall mosaics occur as uninterrupted coatings of entire walls so that the motif of individual panels had to be adjusted to secure continuity of their underlying bar-and-band structure. In Andalusia, the tetragonal structure of the panels and their complexes were locally adjusted to become octagonal quasiperiodic. Only two geometric types of such octagrids were derived in Andalusia, in agreement with the rarity of quasiperiodic ornaments in general. In Morocco, before the panel substructure became heavily masked by an overflow of rosettes of several sizes, the mosaic panel was based on an octagonal quasiperiodic grid and ornamental rosettes were placed in it, disposed in the form of concentric octagons. As a prominent example, the octagonal motif of the Nejjarine Fountain and its plaster encasement will be discussed.

- Human activity as a factor causing the biomass, structure and seasonal
dynamics of phytoplankton in adjacent fishponds-
Free pre-print version: Loading...
Abstract: The role of phytoplankton as one of the main sources of energy entering the water food network is especially evident in fish-rearing ponds. Indeed, in these comparatively small ponds (unlike many lakes), variations in the abundance of phytoplankton can be extremely sensitive to the action of external factors, including human activity. Here, we present results of the analysis of the phytoplankton dynamics in adjacent fishponds and in supplying/recipient river courses upstream and downstream of the ponds during a growing season. In the grow-out ponds, phytoplankton biomass is shown to reach maximums in spring and in early autumn, while in the nursery pond, the phytoplankton dynamics is characterized by one long peak. The specificity of fish-rearing ponds as the human-regulated reservoirs clearly manifests itself under comparison of phytoplankton biomass of ponds with the biomass of phytoplankton inhabiting a nearby river. The averaged phytoplankton biomass in the ponds was 6.2–10.1 times higher than in the river. Besides, we show here that the taxonomic composition of phytoplankton in the river differs significantly from the composition of phytoplankton in the fish-rearing ponds. In particular, Cyanobacteria and Chlorophyta were revealed as the major portion of the phytoplankton in the fish-rearing ponds, while in the river their abundances were low.

- Combined effects of high voltage gradient and electrolyte conditioning on
electrokinetic remediation for chromium (VI)-contaminated soils-
Free pre-print version: Loading...
Abstract: Disposal of chromium-containing industrial waste has led to soil contamination at dispersed locations around the globe. Considering the carcinogenic, non-biodegradable, and bioaccumulating nature of hexavalent chromium Cr (VI), it is pertinent to treat the contaminated soils. Electrokinetic Remediation (EKR) is a promising technology to remediate metal-contaminated soils under the influence of an electric field. This study investigated the removal of Cr (VI) by EKR, enhanced with a combination of high voltage (50 V), electrolyte conditioning using EDTA (0.1 M), and type of electrode material. Under controlled conditions using distilled water, low voltage (20 V at 1 V/cm) resulted in 22% removal, while high voltage (50 V at 2.5 V/cm) resulted in 55% removal of Cr (VI) in 10 h of treatment period. The removal was further enhanced to 77% by amending with ethylenediaminetetraacetic acid (EDTA 0.1 M) as an electrolyte at a high voltage gradient of 2.5 V/cm. Classifying the role of electrode (graphite and stainless steel), based on the removal efficiency and corrosion of electrodes, graphite resulted in higher removal compared to stainless steel but with a significantly higher corrosion effect. Characterization of soil after EKR experiments exhibited improved liquid and plastic limits, and insignificant difference in Total Organic Carbon (TOC) and other parameters related to soil health. Energy consumption and cost-estimation revealed that application of high voltage, along with conditioning of electrolyte with EDTA can significantly increase removal of Cr (VI) in short period of time in a cost-effective (0.8 US$/g) way, thereby can be applied for rapid treatment of large volumes of soil without affecting the properties of soil.

- Egyptian blue, Chinese blue, and related two-dimensional silicates: from
antiquity to future technologies. Part A: general properties and
historical uses-
Free pre-print version: Loading...
Abstract: The ancient Egyptian blue pigment was developed over 5000 years ago and was used extensively for around four millennia until its use mysteriously declined dramatically during the Early Middle Ages. It recently attracted a lot of attention along with some related materials, leading to a fast-growing number of applications in fields, such as sensors, solar concentrators, energy-saving, and medicine. The new surge in interest began in 1996 with the discovery of their intense NIR photoluminescence that surprisingly can be triggered even by visible light. In 2013, the possibility of exfoliating them and producing NIR luminescent nanosheets was established, expanding the family of 2D nanomaterials. More recently, the discovery of their high antibacterial effects and biocompatibility, and very promising optical, electric and magnetic properties, has further boosted their applications. The characteristics of Egyptian blue are due to its main component: the very stable crystalline compound CaCuSi4O10. This tetragonal sheet silicate is the synthetic analogous of the rare cuprorivaite mineral. In Part A of this review, we summarize the historical uses and main properties (i.e., composition, structure, color, stability, luminescence, and biological activity) of cuprorivaite and related 2D silicates, i.e., BaCuSi4O10 (the main constituent of the ancient pigment Chinese Blue), BaCuSi2O6 (the main constituent of the ancient pigment Chinese Purple), SrCuSi4O10 (synthetic analogous of wesselsite) and BaFeSi4O10 (synthetic analogous of gillespite). The Part B of the review will focus on the modern rediscovery of these materials, their modern synthesis and exfoliation, and the innovative applications based on their properties.

by olive fruit fly infestation and olive anthracnose-
Free pre-print version: Loading...
Abstract: Olive pests and diseases influence olive oil quality. Ayvalik olive cultivar is important between local cultivars grown in Turkey. This study aimed to monitor the effects of olive pests and diseases (olive fruit fly attack and olive anthracnose) on Ayvalik olive oil quality parameters such as free fatty acids (FFA), peroxide value (PV), specific extinction coefficients (K232, K270, and ΔK). Besides, Ayvalik olive fruits were collected at six harvest times, and the level of ripening with olive pests was also evaluated. Results showed that the FFA level influenced negatively by olive pests, mainly olive anthracnose. At the end of harvesting, FFA of oils from damaged olive anthracnose reached up to 5.42 (% oleic acid). Except for the first harvest period, the other quality parameters remained between limit values, and slight differences were observed between healthy and damaged olives. At the first harvest period, PV and K232 (7.02 mEq O2/kg, 2.22) of olive oil from fly-infected olive had higher values than the other samples. The stage of ripening, healthy, and damaged olives affected slightly certain fatty acids of the oils. Total phenolics, o-diphenol, and α-tocopherol content of oils from healthy fruits had higher values than oils from damaged olives. Besides, the antioxidant activity of oils obtained from healthy olives showed higher values compared to the oils from infected olive fruits. Graphical abstract

world: a review article-
Free pre-print version: Loading...
Abstract: Preservation of heritage in the Arab world is a subject of extensive investigation. Different urban and architectural heritage preservation projects took place in the Arab world. These projects apply different polices and follow either the American or the European schools of heritage preservation or a hybrid of both. Unfortunately, the majority of these projects are not guided by a unified set of international laws. This study seeks to investigate the presence of an Arabic school for heritage preservation using novel methodologies by reviewing and analyzing 14 urban and architectural heritage preservation projects in African and Asian Arab countries. That were chosen from the reliable documented and governmental preservation projects in the last 20 years following certain selection criteria. The projects included six urban, and ten architectural heritage preservation projects. The researchers can freely say that there is no Arab school for heritage preservation, and there are different limitations with the heritage preservations in its current form. The researchers suggested a number of recommendations to overcome such constraints, enable heritage investment, and take into account aspects of heritage site management in order to achieve sustainability.

Abstract: Nano-chitosan and nano-sodium alginate were prepared. Transmission electron microscopy was used to test the nano-chitosan and nano-sodium alginate morphology and their effects against pathogens and microorganisms. Nano-chitosan and nano-sodium alginate were evaluated as edible coating to improve the microbiological quality of Ras and soft white cheeses during ripening. Nano-chitosan showed maximum antibacterial and antifungal activities with an inhibition zone of 29 mm for Staphylococcus aureus and 12 mm for Aspergillus niger. Sodium alginate nanoparticles treated with 2% acetic acid showed a higher antimicrobial impact than 1% and 1.5% glacial acetic acid at 40 mg/mL. The minimum inhibitory and lethal concentrations of nano-chitosan and nano-sodium alginates were 40, 80 mg/mL, and 80, 160 mg/mL for Staph. aureus and Sal. enteritidis, respectively. The highest decreasing percentage of yeast and fungi was observed in Ras cheese coated with nano-sodium alginate. Chitosan and sodium alginate nanoparticles' edible coating might be promising in food preservation.

Non-destructive Analysis: project overview-
Free pre-print version: Loading...
Abstract: Over the years, transportable instrumentation for cultural heritage (CH) in situ measurements has noticeably widespread, due to logistic, economical and safety reasons. Ion beam analysis, a powerful set of analytical techniques, of great importance for CH, is instead carried out by using fixed instrumentation. To overcome this limit, the Italian national Institute of Nuclear Physics (INFN), CERN (European Centre for Nuclear Research) and the Opificio delle Pietre Dure (OPD), started MACHINA, the “Movable Accelerator for CH In-situ Non-destructive Analysis: the new generation of accelerators for art” to build a transportable accelerator, compact, with strongly reduced weight, absorbed power and cost. MACHINA will be installed at the OPD and dedicated to CH. It will be moved to major conservation centres and museums, when needed. The INFN-CERN proposal, approved in December 2017, became operative in February 2018. 2018 was dedicated to the acquisition of material/instrumentations, to set up both a dummy accelerator (to test the vacuum system) and a vacuum chamber (to test the source). Due to COVID, in 2020 and 2021 the experimental work was slowed down, but we kept developing the control electronics/software and built the second-generation supporting structure. The HF-RFQ power supplies were integrated in October 2021. At the rise of 2022, after conditioning the cavities, we tested the system and in March 2022 we got the first extracted 2-MeV proton beam. In this paper, we present the structure of the MACHINA system, the approach followed and the main solutions adopted, with a special focus on the control system, and finally the first experimental results.

- Estimation of phytoextraction potential of selected halophytes for
accumulation of heavy metals from wetland saline soil-
Free pre-print version: Loading...
Abstract: The phytoremediation is a significant natural clean-up process for removal of heavy metals from wetland saline soils (WS) for the sustainable environmental pollution control. Therefore, the phytoremediation potential of Typha domingensis (southern cattail) and Phragmites australis (common reed) has been evaluated for absorption and accumulation of salts and heavy metals growing at two sites of WS samples coded as BS1 and BS2 (“BS” the soil that is not adjoining to root of plants) in Hyderabad Sindh, Pakistan. The three parts (root, stems, and leaves) of both Plants were obtained from several of locations oxidized the matrices of each part of plants and the corresponding soil samples using acid mixture. A variety of techniques were used to identify the metals by atomic absorption spectrometry. The average values of heavy metals, Co, Cd, Cr, Cu, Pb, and Zn in BS1 and BS2 were found to be (8.53, 14.4, 8.88, 64.3, 13.3, and 142) and (12.4, 18.2, 13.6, 89.4, 14.4, and 124) µg/g, respectively. The data of bioconcentration (BCF) and translocation factors (TF) of the research showed that the studied halophytes showed a high accumulation potential (> 1) for heavy metals from WS. The metal content in plants and rhizospheric soil have a strong relationship (p < 0.01). The screening data based on classical methods and GC–MS indicated that the studied phyto extractants have many phytochemicals. These phytochemicals may have the capability to accumulate heavy metals from contaminated soils. The roots and their rhizospheric soil (RS1 and RS2) have a highly significant relationship of accumulation potential with the selected heavy metals (RS is soil adjoining to roots of plants) (p < 0.01). These halophytes are able to remove heavy metals directly from salty metal-contaminated soil in wetland environments.

Free pre-print version: Loading...
Abstract: Evaluating the Soil Quality Index (SQI affected by continuous and long-term cultivation operations to identify the threat of soil destruction and its controlling is a severe challenge. The current study has investigated the effects of cultivation operations on SQI in a wide area (37,524 ha), and with various types of soil (three soil orders including Inceptisols, Mollisols, and Vertisols) and the record of several decades of wheat cultivation. After determining the total data set (TDS) and minimum data set (MDS), the SQI was calculated using Integrated Quality Index (IQI) and Nemoro Quality Index (NQI) models. The results showed that most soil indicators (e.g., electrical conductivity, sodium adsorption ratio, organic carbon, and bulk density) were negatively affected by long-term cultivation operations. Compared to the control soils, the values of IQI-T, NQI-T, IQI-M, and NQI-M had been decreased ranging from 17 to 24%, 20 to 27%, 17 to 22%, and 21 to 26%, respectively, in the cultivated soils. The most significant decrease in the average SQI value was observed in the Vertisols (24% decrease), followed by Inceptisols (21% decrease) and Mollisols (19.5% decrease). The regression equations indicated that IQI-T, NQI-T, IQI-M, and NQI-M models could explain 59%, 39%, 53%, and 35% and 57%, 37%, 51%, and 33% of changes in the biological and grain yields of wheat, respectively. The current study provides a quantitative method for evaluating the soil quality at the soil type-scale and creatively analyzes the effects of long-term and continuous cultivation operations on the soil quality and product performance.

Abstract: In this research, Juncus acutus and Salicornia perennans communities which have different floristic composition and are developing on soils with different salinity degree in Yeşilırmak Delta were investigated. The phytosociological properties of the communities were analyzed by Braun–Blanquet method. The effect of edaphic parameters on the communities was determined using ordination techniques (CCA). Galatello pannonicae–Juncetum acuti ass. nov. develops on soils with high EC, while Samolo valerandi–Juncetum acuti Korkmaz et al. Ekoloji 21:64–79, 2012 and Spergulario marinae–Salicornietum perennantis ass. nov. develop on soils which have relatively low EC value. Consequently, the edaphic factors showing variation depending on microtopography have affected the plant community distribution in Yeşilırmak coastal wetland sites.
