Radon is the biggest contributor to natural and radiation in the environment and causes long term health concern. The link between tobacco, cigarette smoke and cancer has long been established. Smokers are ten times at greater risk of developing lung cancer than that of non smokers. In this work, the radioactive radon concentrations of some cheroot samples in Myanmar were measured using SSNTDs technique and long term measurements were carried out for period of 100 days. According to the detection of alpha tracks, alpha track density and radon concentrations were carried out. And then annual effective dose of radiation in the corresponding samples were calculated.

Full textAbstract:
This paper addresses the Byzantine vessels featuring monograms excavated in Cherson and in Cembalo, and their interpretation and significance for the life of the Greek population of the south-western Crimea. So far, archaeological researches discovered 15 vessels made in Byzantium, which showed monograms of the life of saints (“George,” “Michael,” and “Prodromos”), the family name “Palaiologos,” and also code letters “A” (“relic”) and “K.” These vessels were containers for holy water, and in a few cases, plausibly, for myrrh. These vessels were delivered to Cherson and Cembalo as gifts or eulogiai from Constantinople (?), as a part of ideological propaganda. The comparative archaeometric study of the three samples from Cembalo castle in a lab of the University of Lyon revealed one vessel’s similarity with the products of a fourteenth-century pottery workshop discovered in the vicinity of Istanbul. Although two samples more belong to a group different from the said workshop’s products, they still show similar technological parameters. The chronology of the vessels in question lays within the 1320s–1350s in Cherson and from the second half of the fourteenth to the early fifteenth century in Cembalo.

Full textAbstract:
The aim of the present study was to evaluate hepatitis A virus (HAV) and hepatitis E virus (HEV) contamination in mussels (Mytilus galloprovincialis) from Cherrat estuary (Moroccan Atlantic Coast), Morocco. In total, 52 samples (n = 12 mussels/each) were collected at four sites in the estuary, monthly, between March 2019 and March 2020. HAV and HEV were detected by real-time reverse transcription polymerase chain reaction (RT-PCR) according to the ISO/TS 15216 method. HAV was detected in 46.15% of analyzed samples. Conversely, HEV was not detected in any sample. Moreover, the HAV detection rate was significantly associated with seasonal rainfall variations. This qualitative study on HAV and HEV contamination highlights the interest of studying mussel samples from wild areas. As HAV presence in mussels represents a potential health risk, viral contamination surveillance of mussels is necessary to protect consumers. HAV shellfish contamination must be monitored at Cherrat estuary because of the role played by shellfish as HAV reservoirs and/or vehicles in fecal-oral HAV transmission.

Full textAbstract:
Although the aspects of the production of Byzantine-Cherson cast coins and the technological nuances of their manufacture have been repeatedly studied in Russian scholarship, every time there appeared various hypotheses and assumptions, mostly remain highly debatable so far. For a long time, the lack or difficulties of access to the special equipment allowing the one to determine coin alloys allowed the researchers to draw conclusions about the coin material only against the background of some definitions from the scholarship and visual indicators. Among the disputable aspects is the casting of Cherson-Byzantine lead coins. In this connection, we have studied 30 specimens of coins by laboratory research of the alloy composition by X-ray fluorescent analysis. The samples selected for examination visually suggested a high content of lead. It has been found out that in the samples examined have similar elemental composition of coin alloy, lead with additions of arsenic. It is possible that, in the Byzantine Period, the Taurica received lead from the mines located in the Caucasus area, which were typical of a high content of arsenic. The most part of the of samples (27 specimens) contained more than 2/3 of lead; the alloy of three coins contained similar proportions of copper and lead. Taking the said results into account, we can suppose that the “almost pure” lead coins most likely were a specific kind of technological “flaw” in the casting in Cherson. It is still possible that, in the sorting of the ready-made coins, the specimens not corresponding to the standard samples and having casting defects (partial casting of the mould or lead casts) were withdrawn and returned to remaking. This interpretation explains why the so-called “lead” coins are relatively rare: they occurred mostly in the coinages from the age of Basil I and Leo VI, though in some series they were unique or unknown.

Full textAbstract:
One of the key elements affecting structural concrete's strength and longevity is the cement's quality. In Pakistan, large amounts of cement are utilized in construction projects. This study appraised some physical properties of five brands of Portland cement bought from cement industries in KPK. Cement brands are investigated, including Cherat cement, Askary cement, Luckey cement, Kohat +, and Bestway cement. The composition of the cement has been recorded from the cement bags. Each initial setting time, normal consistency, final setting time, fineness, and compressive strength cement samples (collected as bags from the market) have been tested in the laboratory at three days, seven days, 14 days, and 28 days per ASTM standards. Amongst these various cement brands in KPK, we aim to investigate the best cement brands taking into consideration the above all physical test and then test these brands after three months. Taking time as a factor, the best cement quality is to be found. According to the fineness of cement, Cherat cement is found to be the best amongst all five brands of cement when tested initially, while lucky and Kohat were the least in fineness properties. Consistency tests were performed for all brands of fresh types of cement, and Cherat and Kohat have more consistency, while Askary has the least consistency. Initial and Final setting time tests were performed for all brands, and Cherat cement was found to have the more initial and final setting time, while Kohat and Askary had the least setting time. In the case of the compressive strength test, Cherat cement was found to be the greater strength, while lucky had the least compressive strength. For seven days curing. For 28 days curing Cherat cement was the best one having greater strength, while Askary had the least strength among all. All the cement brands were tested the same way after three months of age, which shows that all five brands crossed the ranges for each test. Still, it has been observed that the decrease in the fineness is small for Cherat compared to all other brands while in case of compressive strength, the decrease in Cherat is greater than all other brands.

Full textAbstract:
The analyses of raw material provenance offers the possibility of tracing short and long-distance raw material transport. So far, most studies of raw material of flint and chert in Europe have been based on macroscopic analyses. We apply infrared spectroscopy to Aurignacian assemblages from Vogelherd cave and to the Magdalenian site Randecker Maar in southwestern Germany. We compare raw material samples from three chert-bearing areas in Germany with archaeological samples from Vogelherd. Our results show that infrared spectroscopy can distinguish between different raw materials. Our archaeological samples from Vogelherd correspond to the sampled geological cherts in terms of their spectral signature. Our comparison of reference samples and archaeological samples highlights problems in commonly used macroscopic identifications of chert raw materials.

Mussels filter large amounts of water to extract nutrients; therefore, they can concentrate and accumulate in their tissues infectious agents, and vectors of enteric diseases. The aim of this study was to assess mussel contamination by Norovirus genogroups I and II in the Cherrat estuary to determine the public health risk linked to their consumption. Mussels (Mytilus galloprovincialis) were collected (n=52 samples; 12 mussels/sample) at four sites (S1 and S2 located on the right rocky bank / S3 and S4, located on the rocky left bank) in the Cherrat estuary (Casa-Settat region), Morocco, during 13 months, from March 2019 to March 2020. Norovirus was detected and quantified by real-time Reverse Transcription-Polymerase Chain Reaction (RT-PCR). Norovirus genogroups I and II were detected in 17.30% and 94.23% of mussel samples, respectively. Contamination by Norovirus (genogroups I and II) was not correlated with seasonal factors (month and rainfall), and Norovirus prevalence was comparable among the four sampling sites. Consumption of raw or undercooked mussels contaminated with Norovirus can cause gastroenteritis, which represents a potential risk to human health. The present study would be helpful to control and manage the potential risk to the public health of the Moroccan population due to the degradation of water quality continuously impacted by runoff, the urban wastewater treatment system malfunctions, and overflows from nearby sewage systems.

Research subject. The paper presents the results of a study into the carbonate-terrigenous section of 197.8 m-thick Wenlockian section in the Shchugor River basin, which is proposed as the stratotype of the regional horizon. Materials and methods. The study was based on numerous samples from Lower Silurian deposits collected by the authors in different years during fieldwork on the Western slope of the Circumpolar Urals and the Chernov and Chernyshev uplifts, as well as the biostratigraphic, paleontological, lithological, and C-isotopic data obtained during these works. Results. The obtained data allowed revising some of the established ideas about the structure of the Lower Silurian section and the position of the boundary level between the Llandoverian and Wenlockian in the Subpolar Urals and to identify a new regional subdivision with the name “Voyvyv”. The traced formation conditions of shallow carbonate sediments of the Voyvyv horizon and the consistent change of zonal taxa of marine fauna in the stratotype section indicate similarity with coeval strata on the Chernov and Chernyshev uplifts and Dolgy Island. Conclusions. The results of the study of Wenlockian Voyvyv deposits in the Timan-North Urals region showed that the section in the Shchugor River basin in outcrop 10c can be considered the most informative in the Northern Urals region in terms of exposure degree, established stratigraphic completeness, and preservation of macro- and microfauna.

Full textAbstract:
AbstractPublished and unpublished iron isotope data from banded iron formations (BIF) and their BIF-hosted hypogene (hydrothermal) iron ores from the Quadrilátero Ferrífero (itabirites), Corumbá, and Carajás iron districts in Brazil, as well as from the Hamersley province in Australia are presented and discussed. BIF constitutes a typically thinly bedded or laminated chemical sedimentary rock, with ≥ 15% Fe and layers of chert, chalcedony, jasper, or quartz, whereas itabirite is considered a laminated, metamorphosed iron formation rich in iron oxides, which may contain carbonate minerals, amphiboles, and abundant quartz. For the Paleoproterozoic Quadrilátero Ferrífero district, the range in δ56Fe values of hypogene iron ores is similar to that of the metamorphosed BIFs, and iron isotope variations are better distinguished in different regional deformational domains. Light isotopic compositions dominate in the low deformation domain (δ56Fe = −0.42 ± 0.12 to 0.29 ± 0.04‰), whereas the eastern, high-strain domain is characterized by heavy values (δ56Fe = −0.09 ± 0.08 to 0.37 ± 0.06‰; Mendes et al., Mineral Deposita 52:159–180, 2017). Iron isotope composition for the Neoproterozoic iron formations of the Corumbá region (hematitic, dolomite-rich: −1.83 and −0.83‰; cherty-hematite: δ56Fe −0.49‰) are controlled by: (1) primary seawater signature, (2) microbial activity, and (3) supergene goethite alteration. Hydrothermal alteration is reflected in the oxygen isotope data, but apparently not in the iron isotope fractionation. Iron and oxygen isotope pairing shows that δ56Fe values increase, while δ18O values decrease. In the Archean jaspilites of Carajás, hypogene ores tend to display lighter δ56Fe values than their host BIF counterparts. Also, there is a correlation between coupled iron and oxygen isotope values that is clearer towards lighter isotopic values, especially for δ18O. In the Paleoproterozoic Hamersley deposits, correlation between δ18O and δ56Fe values suggests a direct correlation of both isotope systems during low-grade, greenschist-facies metamorphism. On the other hand, despite the evident shift to negative δ18O values and apparent preservation of the metamorphic δ56Fe signature, iron ore and hydrothermally modified BIF show a correlation between δ18O and δ56Fe values. In contrast, in supergene-modified samples a negative correlation is apparent. The Carajás (+1.24 to + 0.44; one sample − 0.30‰) and Hamersley (+ 1.02 to − 0.29‰) hypogene ores display δ56Fe in a similar interval, reaching positive values, whereas ores from the Quadrilátero Ferrífero show a tendency towards lower values (to − 0.80‰). This review indicates that the application of iron isotopes in exploration is presently limited mainly due to the restricted dataset available for ore samples. Nevertheless, and despite all local differences, there is a general tendency for hypogene ores to display moderately lighter δ56Fe values for all deposits compared to precursor BIF. In contrast, a strong supergene imprint in ore leads to moderately heavier δ56Fe values. As more data become available, and if these trends are confirmed, the use of this tool may be valuable in the future, for instance to decipher the hypogene or supergene origin of specific ore zones, and as a consequence the probable depth extension or interpretation of concealed, deep orebodies.

Full textAbstract:
ABSTRACT In a reconnaissance investigation aimed at interrogating the changing topography and paleogeography of the western United States prior to Basin and Range faulting, a preliminary study made use of U-Pb ages of detrital zircon suites from 16 samples from the Eocene–Oligocene Titus Canyon Formation, its overlying units, and correlatives near Death Valley. The Titus Canyon Formation unconformably overlies Neoproterozoic to Devonian strata in the Funeral and Grapevine Mountains of California and Nevada. Samples were collected from (1) the type area in Titus Canyon, (2) the headwaters of Monarch Canyon, and (3) unnamed Cenozoic strata exposed in a klippe of the Boundary Canyon fault in the central Funeral Mountains. Red beds and conglomerates at the base of the Titus Canyon Formation at locations 1 and 2, which contain previously reported 38–37 Ma fossils, yielded mostly Sierran batholith–age detrital zircons (defined by Triassic, Jurassic, and Cretaceous peaks). Overlying channelized fluvial sandstones, conglomerates, and minor lacustrine shale, marl, and limestone record an abrupt change in source region around 38–36 Ma or slightly later, from more local, Sierran arc–derived sediment to extraregional sources to the north. Clasts of red radiolarian-bearing chert, dark radiolarian chert, and quartzite indicate sources in the region of the Golconda and Roberts Mountains allochthons of northern Nevada. Sandstones intercalated with conglomerate contain increasing proportions of Cenozoic zircon sourced from south-migrating, caldera-forming eruptions at the latitude of Austin and Ely in Nevada with maximum depositional ages (MDAs) ranging from 36 to 24 Ma at the top of the Titus Canyon Formation. Carbonate clasts and ash-rich horizons become more prevalent in the overlying conglomeratic Panuga Formation (which contains a previously dated 15.7 Ma ash-flow tuff). The base of the higher, ash-dominated Wahguyhe Formation yielded a MDA of 14.4 Ma. The central Funeral Mountains section exposes a different sequence of units that, based on new data, are correlative to the Titus Canyon, Panuga, and Wahguyhe Formations at locations 1 and 2. An ash-flow tuff above its (unexposed) base provided a MDA of 34 Ma, and the youngest sample yielded a MDA of 12.7 Ma. The striking differences between age-correlative sections, together with map-based evidence for channelization, indicate that the Titus Canyon Formation and overlying units likely represent fluvial channel, floodplain, and lacustrine deposits as sediments mostly bypassed the region, moving south toward the Paleogene shoreline in the Mojave Desert. The profound changes in source regions and sedimentary facies documented in the Titus Canyon Formation took place during ignimbrite flareup magmatism and a proposed eastward shift of the continental divide from the axis of the Cretaceous arc to a new divide in central Nevada in response to thermal uplift and addition of magma to the crust. This uplift initiated south-flowing fluvial systems that supplied sediments to the Titus Canyon Formation and higher units.

This chapter presents a case study of a previously excavated lithic sample from Santa Rita Corozal, considering stone tool production at two structures, 216 and 218. Both exhibit a higher number of Postclassic chert and chalcedony lithic artifacts than other contemporary structures excavated at the site. The authors use debitage analysis to reveal how two households crafted formal tools locally and visual sourcing analysis to better understand how these tools articulated with broader traditions of lithic craft production in a regional exchange network. In contrast to the commercial level of production exhibited at Colha, Belize, these households used a variety of source materials and produced a less standardized tool kit on a much smaller scale.

Full textAbstract:
ABSTRACT The Shublik Formation (Middle and Upper Triassic) is a mixed siliciclastic-carbonate-phosphatic unit in northern Alaska. It generated oil found in Prudhoe Bay and other accumulations and is a prospective self-sourced resource play on Alaska’s North Slope. Its distal, deeper-water equivalent—the Otuk Formation—consists largely of radiolarian chert, mudstone, and limestone and contains potential gas accumulations in the Brooks Range foothills to the south. New petrographic, fossil, geochemical, spectral gamma-ray, and zircon U-Pb data yield insights into facies changes in these units, which were deposited across a shallowly dipping shelf margin in a high-latitude setting. Samples come from four localities along a transect that extends ~410 km from present-day northeast (proximal) to southwest (distal) in northwest Alaska. Proximal Shublik facies (Brontosaurus 1 well) contain abundant siliciclastic detritus and local phosphate. Shublik-Otuk transitional facies occur in the probable onshore extension of the Hanna Trough (Surprise Creek); new zircon U-Pb data indicate an early Norian age for a bentonite bed in this section. Distal Otuk facies (Red Dog district, Cape Lisburne) are fine grained, biosiliceous, and organic rich. New detrital zircon U-Pb data from a distinctive sandstone member in the Otuk Formation at Cape Lisburne reinforce previous interpretations of a provenance to the present-day northwest and indicate a protracted history of Triassic magmatism for this source area. Triassic facies patterns in northwestern Alaska were shaped by sea-level change, climate, and regional tectonism. Organic-rich facies developed best at times (Ladinian–middle Norian) and/or in settings (distal shelf, Hanna Trough) with minimal dilution of organic matter by other detritus.

Full textAbstract:
Abstract Natural hydrogen is one of the key elements in the green energy initiative for the carbon net zero strategy of the world. Serpentinization is known as the most common process that generates natural hydrogen. This research work is aimed to gain a deeper understanding of the mineralogical composition and distribution of ophiolites in Peninsular Malaysia and to evaluate the potential of natural hydrogen generated from serpentinization processes. Field studies were conducted in various areas along the Bentong-Raub suture zone to study ophiolite rock occurrences in the suture zone. Standard petrographic and X-ray Diffraction (XRD) analyses were conducted to examine the mineralogical and chemical composition of rocks samples. The results show the majority of samples contain a significant amount of serpentine minerals such as antigorite, cronstedtite and lizardite, as well as some unaltered ultramafic minerals (e.g., forsterite, fayalite, pyroxene and hornblende), and secondary minerals (e.g., magnetite and chromite). The degree of serpentinization varies between 15% and 93% of the bulk volume with most samples exceeding 75%. Samples collected at Sungai Koyan, Cheroh, Bentong, and Bukit Rokan are characterized by high concentrations of antigorite, a type of Mg-rich serpentine. In contrast, cronstedtite, a Fe-rich serpentine mineral, is the dominant species in the samples from the Petaseh area. The mineralogy of the samples indicates hydrogen generation occurred via the reaction between fayalite (Fe-rich olivine) reaction with water, which is consistent with the observation that a significant amount of magnetite was found within samples from the Petaseh outcrop. Findings from a geochemical and mineralogical analysis reveal a significant serpentinization process along the Bentong-Raub suture zone, ultimately producing a substantial amount of hydrogen. These results highlight a potential natural hydrogen source in Peninsular Malaysia; however, supplementary research is necessary for further evaluation.
