Published: October 2021

Honey produced by bees from nectar in flowers and plants, is an aqueous supersaturated sugar solution, mainly monosaccharide (fructose and glucose) (70%–80%) and water (10%–20%). 5-Hydroxymethylfurfural (5-HMF) content in honey bee is an indicator of the purity. High concentration of 5-HMF in honey bee indicates overheating and poor storage conditions (The chemical properties of honey, free acids and total acids) significantly in correlation with the HMF content and provides parameters that are used to make quick assessments of honey quality (Khalil et al., 2010). The recommended value of 5-HMF (Alinorm 01/25, 2000) and the European Union (Directive 110/2001) in honey usually should not exceed 80 or 40 mg/kg, respectively. This work aims to examine the concentration of 5-Hydroxymethylfurfural (5-HMF) content in different Qatari honey bee samples as an indicator of the honey bee quality by using the reference White Method.

Published: October 2021

Qatar fertilizer company (QAFCO) is one of the world’s largest single site producer of ammonia and urea with production capacity of 12,900 metric tons per day. Currently, QAFCO faces major challenges in terms of water streams management that is generated from many processes such as wastewater from Harbor-Bosch process and brine solution from multi-stage flash (MSF) desalination process. To protect the environment; QAFCO has been making an effort to minimize the disposal of all types of water disposed into the sea. Here, this project proposes to develop a viable and economically effective process that can reach zero-liquid discharge (ZLD) of all processed water or wastewater from QAFCO facilities. The best method for ZLD is membrane distillation crystallization (MDC) hybrid process that concentrates and minimizes the volume of wastewater/brine streams to form solid through crystallizer. Membrane distillation (MD) is a thermally driven membrane process. It applies low-grade energy to create a thermal gradient across a microporous hydrophobic to vaporize water in the feed stream and condense the permeated vapor in the cold side. This research work aims to evaluate the performance of MDC for ZLD using commercial/fabricated electrospun nanofiber membrane (ENM) PVDF –base membranes at different type water streams. A general observation, higher water vapor flux and water recovery were exhibited at higher feed conductivity at 70°C. Moreover, the fabricated hydrophobic PVDF ENMs results confirmed the formation of nanofiber at the membrane surface using scanning electron microscopy (SEM). In addition, the water contact angle values of PVDF ENMs were greater than 100° and have stable mechanical and chemical properties. The ongoing research work will conduct a comparison between the optimum PVDF ENMs and the commercial MD membranes in terms of water recovery, salt rejection%, fouling/scaling, amount of collected solid and energy consumption at optimum operating conditions in MDC. In addition, it will perform a techno- economic feasibility assessment of the MDC hybrid process.

The spin coating technique has been used to deposit the nanocomposite film on the Interdigitated ITO electrode.
Origin of TPHs and PAHs in Marine Sediment nearby Oil and Gas Extraction Sites on the West Coast of Qatar
Authors: Abdulla Maryam Abdulali , Castillo Azenith
Published: October 2021

Total Petroleum Hydrocarbons (TPHs) and Polycyclic Aromatic Hydrocarbons (PAHs) are priority pollutants, which are known to be associated with petroleum products. They are released into the marine environment via accidental spillage, exploration and transportation. The present study aims to investigate the type, origin and weathering of petroleum in the coastal marine sediment of the western coastline of Qatar. Sixty-six surface sediment samples were collected along the western coastal area. The concentrations of organic hydrocarbons (TPHs and PAHs) were determined using GC-FID and GC-MS, respectively. Sediment characteristics including pH, temperature, TOC and particle size were also measured. The results indicated low concentrations of TPH (<0.001-0.246 µg/g dry weight sediment) and PAHs (<0.001-0.044 µg/g dry weight sediment). The concentrations for both organic pollutants were lower compared to the previous studies done within Qatar and in the Arabian Gulf and also indicated below the available permissible limit set by the Ministry of Municipality and Environment of Qatar and other Sediment Quality Guidelines (SQGs) used worldwide (NOAA). Pollution concentration profile is site specific where concentrations are high within the proximity of the source and derived from both direct inputs of petrogenic and pyrogenic contribution.

Authors: Abdelatty Rokaya Hamdy , Khan Adnan , Yusuf Moinuddin , Alashraf Abdullah , Abdul Shakoor Rana
Published: October 2021

This research work aims at investigating the influence of a fixed content of silicon nitride (Si3N4) and varied contents of graphene nanoplatelets (GNPs) on the physical and mechanical properties of Al-Si3N4-GNPs composites. The composites were fabricated by a microwave-assisted powder metallurgy route. The Si3N4 concentration was fixed at (5 wt.%) while the GNPs concentration was varied between (0 wt.%) to (1.5 wt.%) in the Al-Si3N4-GNPs. The structural analysis indicates the formation of phase pure materials with high crystallinity. The microstructural analysis confirmed the presence of the Si3N4 and GNPs showing enhanced agglomeration with the increasing amount of GNPs. Moreover, the surface roughness of the synthesized composites increases with an increasing amount of GNPs reaching its maximum value (RMS = 65.32 nm) at 1.5 wt.% of GNPs. The Al-Si3N4-GNPs composites exhibit improved microhardness and promising load-indentation behavior during nanoindentation when compared to pure aluminum (Al). Moreover, Al-Si3N4-GNPs composites demonstrate higher values of compressive yield strength (CYS) and ultimate compressive strength (UCS) when compared to pure Al despite showing a declining trend with an increasing amount of GNPs in the matrix. Finally, a shear mode of fracture is prevalent in Al-Si3N4-GNPs composites under compression loading.

Published: October 2021

Oxide nanoparticles are among the most used nanomaterials and have received considerable attention over their potential ecological effects. Increasing investigations report toxicity of certain oxide nanoparticles, however, there are also studies showing opposite results, highlighting the fact that these nanoparticles may differ in their toxicological effects, which depend on particle variety and size, test organism species, and test method. The current study investigates the ecotoxicity of SnO2 nanoparticles on a local marine algae isolate. Five different concentrations (1, 5, 25, 50 and 100mg/L) were tested and the culture was followed for 72h. Algae growth, morphology and metabolites were followed each 24h. The obtained data showed that the SnO2 presented a toxicity on the algae growth that was decreasing with the dose, with lower doses presenting more negative impacts than the higher doses. In parallel, the slow growth observed at 1-5 mg/L was explained by the dramatic damages caused by the SnO2 on the cell morphology, which was detected using the scanning electronic microscopy. Indeed, this low negative impact of higher concentrations of SnO2 (50-100mg/L) is explained by the high agglomeration of ten particles leading to reduced effect on the cell morphology and health. Furthermore, and in accordance with the morphological data, the metabolites analysis data revealed that SnO2 nanoparticles induced stress, which was manifested by an increase in the lipid content and decrease in the proteins, a metabolite that is involved in the algal growth.

Abstract The quality of the air we breathe is important for a healthy life. The use of fossil fuels has increased continuously since the second half of the 19th century. Gases or dusts released into the atmosphere during overproduction,
increased consumption waste can reduce air quality on a global scale. In order to reduce the spread of the coronavirus epidemic that emerged towards the end of 2019 and spread around the world, restrictions began to be imposed
on human activities. With the announcement of the COVID-19 case on March 11, 2020 in Turkey, a series of measures restricting human activities started to be taken starting from March 16, 2020. On the basis of restriction, it is
aimed to prevent the spread of the virus, which has the ability to spread through contact, and to slow the rate of spread. The change in air pollution values due to different restrictions of human activities has been a subject
of curiosity. The results of the study showed that the reduction of human activities significantly affects air pollution. In this study, the changes in PM10 pollutant concentrations in Istanbul and Ankara in the months when more
measures were not taken and in the months when more measures were taken in 2019 and 2020 were examined. As a result of the restrictions applied, the use of vehicles, industrial activities, fuel consumption, etc. It was observed
that the change caused a decrease in PM10 pollutant concentrations.

Air pollution exhibits a very complex and non-linear behavior as a result of positive and negative changes in time and space, depending on the meteorology and topographic structure, in the transportation of the emissions released into
the receiving environment as a result of the activity of air pollution sources. The aim of the study is to monitor the behavior of air pollutants over Van in 2019 through statistical analysis of data, to contribute to increasing
air quality. PM10 and SO2 parameters have been observed to have the highest average hourly value of 72.5-25.1 µg/m³, and the lowest value (24.8 µg/m³ at 22:00 hours,11.4 µg/m³ at 16:00 hours) respectively. It can be seen 64% of
the measured PM10 data were observed in the range of 0.1-40.7 µg/m³. 80% of the same data is less than 56.4 µg/m³ and 91% of the data has the highest density observed in the range 1.1-82.1 µg/m³. while 77% of the measured SO2 data
was observed in the range of 1.5-22.7 µg/m³. 80% of the same data is less than 25.1 µg/m³ and 90% of the data has the highest density in the range of -4.7-37.8 µg/m³. The results also showed wind plays an effective role in the
horizontal transport of pollutants in the atmosphere. If the wind is calm, the polluted air stays where it is, and the precipitation help collapse pollutants in the atmosphere, because of this feature, precipitation is described
as the cleaner of the atmosphere.

Published: October 2021

This investigation aims at to present the Islamic view about the protection of water sources, its significance, comparison with modern study and to depict the distinctions and similitudes if any. Furthermore, this study will exhibit that Islamic learning could play a pivotal part in protection of water sources, conserving its usage and avoiding its wastage. But unfortunately, this aspect is neglected in our curricula that is why the people are unaware about its importance, consumption and scarcity. Water sources not only in the world but also in our country are getting to be depleted and contaminated very quickly. Today, around 60 percent of water sources are too polluted and exhausted for swimming and aquaculture. This situation demands some most appropriate and suitable simple measures from the human beings of the entire world otherwise the shortage of the water would not far away from us in some decades and the whole world would become a barren desert. By simply executing a few sustainability initiatives by promulgating and disseminating the Islamic learning, we can save water and avert contamination. In this way, we could save the precious life of our forthcoming generations and protect the aquatic and terrestrial animals and plants too. In this study, creativities and procedures to protect the water sources have been described in the light of Shariah and according to modern research tools of water research and technology.

The topography of Hermione—A preliminary outline
Authors: Gerding Henrik
Published: October 2021

The preliminary results of a survey of ancient Hermione (epichoric Hermion) are presented in this paper. The survey was conducted during three short campaigns over the period 2015–2017, and focused on the urban layout and development of the ancient city. Because the ancient city area more or less coincides with modern Ermioni, the investigation was mainly restricted to the documentation and analysis of architectural remains that were both still visible above ground and accessible. However, the report also includes a thorough re-evaluation of previous scholarship, taking into consideration remains that are no longer visible. The author identifies three questions of particular interest, relating to the exact location, extent, and potential relocation of the ancient city, and points to the lack of a coherent interpretation. On the basis of present data, the author proposes that Hermione was indeed relocated to a new site, less than 1 km away from its original position, in the early 3rd century BC, and highlights the urban, social, and religious consequences of such an event. However, pending further evidence, the suggested scenario remains a hypothesis.
The cisterns of the Bisti promontory at Hermione. With a preliminary description of the Roman aqueduct
Authors: Klingborg Patrik
Published: October 2021

This article reports the findings of the fieldwork exploring the cisterns at the Bisti promontory of Hermione, executed as part of a collaboration between the Ephorate of Antiquities of the Argolid and the Swedish Institute at Athens. In order to better understand the function of the cisterns within the water supply system, the article begins by presenting an overview of existing water resources in the area, primarily the naturally occurring sources and the city’s 2nd-century AD Roman aqueduct. Following this the study describes the remains of the 14 potential cisterns on the Bisti. Based on the empirical material the similarities and contrasts between these are explored, as well as what they can tell us about the history and life in ancient Hermione. In particular, the article suggests that the presence of the cisterns contributes to our understanding of the urban fabric of the city, and reveals important information about when the city was moved from the Bisti to the nearby Pron Hill.
Life and death in ancient Hermione. Excavations in the necropolis
Authors: Kossyva Angeliki
Published: October 2021

The wealth of ancient Hermione is no longer visible: continuous habitation from c. 3000 BC down to the present day has obliterated most traces. Important information on the social organization and economy of Hermione can however be drawn from the tombs that have been unearthed. A large cemetery was discovered in the early 20th century just outside the city gate, stretching along the road leading to ancient Mases and in continuous use for a period of 1,500 years. It covers an area of 1.5 km east–west along the modern Hermione–Kranidi rural road, taking in the terrain to either side to a width of 160 m and extending south to Pron Hill and north to a patch of level ground some 60 m wide. In this article we focus on cemetery finds unearthed in the area south of the present-day Gymnasium-Lykeion school of Hermione, as they typically reflect the urban organization and economic development of the ancient city. These two themes comprise some of the goals pursued in the collaborative research programme between the Ephorate of Antiquities of the Argolid and the Swedish Institute at Athens.
From 2D and 3D documentation to 4D interpretation. Building archaeological conclusions and workflow strategies gained by remote study of Insula V 1, Pompeii
Authors: Leander Touati Anne-Marie , Staub Thomas , Forsell Renée
Published: October 2021

The text describes new methods elaborated for and used in the building archaeological assessment of a city block, studied first on site, then remotely by members of the Swedish Pompeii Project. Use of a digital platform, with collected wall observations and analysis, systematic photographic documentation of all standing structures, and 3D models, allowed discussion to proceed after the fieldwork came to an end. The models provided new possibilities and new angles of approach, e.g. examining walls at any given point, studying boundary walls as wall-strings in their full extent, allowing all kinds of sectioning at will, introducing bird’s-eye views as a new perspective in study, and measuring wherever needed. The joint results obtained are summed up in a four-phase development of the use of space: the earliest structures; the late Samnite building boom (2nd century BC); the colony (second half of 1st century BC); the imperial era (until AD 79). This narrative includes conclusions concerning building process and development of masonry techniques and on changes in way of life. Many results affect Pompeian archaeology in general. Results of particular importance concern the character of the early plot division and the understanding of the building process creating the double-atrium house of Caecilius Iucundus, including an anchorage in time for this creation in the Claudian period. The relatively small impact in terms of damage that may be ascribed the literary recorded earthquake of AD 62/63 is also worth noting. The text ends with a suggestion of a new workflow for insula studies.

This paper presents a new tomb complex of the Late Bronze Age at Palaepaphos-Teratsoudhia in south-west Cyprus. Although looted, Tomb 288 yielded a representative repertoire of funerary gifts, including seals and scarabs, ranging chronologically from the very beginning of the Late Bronze Age to Late Cypriote IIC, roughly from 1650 to 1200 BC. Tomb 288 has characteristics which are typical of Late Bronze Age tomb architecture in Cyprus and well known in the Paphos region, as well as aspects which have not previously been observed in any necropolis of the period, such as the large central “pillars” which support the roof in Chambers A and B. The tomb’s finds comprise representative examples of the ceramic production of Palaepaphos for a period of some 400 years and illustrate the wealth of this region during the whole of the Late Bronze Age. The tomb is a significant addition, in particular, to our knowledge of the earliest phase of the city’s existence, a period which is not adequately known since the focus of recent research has primarily been on the latest phase of the Late Bronze Age and the early part of the Iron Age.
Ancestral and chthonic cults at Tenos
Authors: Kourou Nota
Published: October 2021

This paper presents the material evidence from two neighbouring Early Iron Age sites at Xobourgo on Tenos, identified as sacred places, and comments on their religious character and evolution. The first, conventionally named the Pro-Cyclopean Sanctuary, has a purely mortuary character. It starts in the Late Protogeometric period with an ancestral cult on a pebble platform over an empty grave, continues with a number of pyre pits inside enclosure walls, and ends up with a chthonic cult at an eschara in the Late Geometric period to be replaced by a small sacred oikos in the 7th century. The second starts as an open-air shrine, named the Pre-Thesmophorion Shrine, with an eschara and a protected place for storing pithoi, and it is turned into a Demeter sanctuary, a Thesmophorion, with a small temple in the Classical period. After considering the development and phases of both sites, it is claimed that they have similar, though not identical, cultic roles. Their different architectural and religious evolution is considered as largely dependent on social changes and historical conditions. They are compared and discussed against contemporary archaeological evidence for ancestral and chthonic cults focusing on such evidence from Tenos.
The Temple of Zeus at Lebadea. The architecture and the semantics of a colossus
Authors: Kanellopoulos Chrysanthos , Partida Elena
Published: October 2021

The Temple of Zeus Basileus at Lebadea rests almost unknown. Its physical remains and date (not systematically explored so far) pose a riddle, as regards not only the circumstances which entailed its presumed incompletion but also the historic context in which the commencement of construction can be embedded. The dimensions of the krepis alone render this edifice highly interesting in the history of temple-building. The in situ preserved architectural elements suggest that here was begun the erection of what was at the time the largest peristasis in Mainland Greece. The temple stylobate measures 200 feet/podes in length, with a lower column diameter equal to just over two metres, and the longest interaxial spacings and corresponding architraves of its time. By increasing the length and height of the structure, the architects achieved its qualification as colossal. This qualification is revealed from the uniquefor-the-Classical-period length of 14 columns along the peristasis, with visible euthynteria and hypeuthynteria courses. As shown in this paper, this colossal structure abided by the rules of Doric design. Ascribing the unfinished state of the temple probably to financial shortcoming and/or military adventures, Pausanias did comment on its ambitious, gigantic size. The level of construction eventually reached is another focal point of our investigation. The study of the Temple of Zeus Basileus brings out the multifaceted notion of the term “monumentality”, tightly related to visual impact. One of the aims of its commissioners would have been to establish a landmark on the summit where Zeus was probably co-worshipped with Trophonios, the Boeotian hero-prophet. Since the temple in question, as we propose, most probably commemorated both a grandiose military victory in the 3rd century BC and the contemporary political situation, its imposing volume, along with the aesthetic effect of bichromy, were meant to perpetuate the overtone of these events within the ambience of the sacred Lebadea. Another facet of monumentality involves the respective building programme, and it derives from epigraphical sources, namely a contract specifying construction details, with particular instructions already at the orthostate level, denoting that accuracy in execution safeguarded the high quality of ancient Greek architecture.
Weight-length relationship and condition factor of Mugil cephalus (Linnaeus 1758, Mugilidea) in the special wildlife reserve of Gueumbeul (RSFG) in Senegal

The weight-length relationship and the condition factors are fundamental parameters with several uses in biology, fish ecology and fisheries management. Thus, in the Special Wildlife Reserve of Gueumbeul (SWRG) in Senegal, the weight-length relationship and condition factor were established for Mugil cephalus (Linnaeus 1758). A total of 311 individuals (97 females and 214 males) of M. cephalus were collected by the artisanal fishery using cast nets. The total length and weight ranged from 11.1 to 25 cm and 15.9 to 145.26 g, respectively. The results showed that in the SWRG, both in females (b = 2.60) and males (b = 2.899), M. cephalus had negative allometric growth. The analysis of variance showed no significant difference (p > 0.05) in the coefficients of determination between females (R = 0.96) and males (R = 0.84). Condition factors (K) were 3.07 and 1.23 for males and females respectively for M. cephalus in the reserve.

Background: The Coronavirus disease 2019 (COVID-19) disease is a pandemic disease spread worldwide and results in lifestyle changes in areas affected by COVID-19. The ongoing social distancing and lockdowns may negatively impact access to medical care and management of type 2 diabetes mellitus (T2DM). Accordingly, we examined the impact of the COVID-19 virus pandemic in Thailand on the glycemic control of patients with T2DM. Method: This study focused on T2DM outpatients at Rajavithi Hospital. Three hundred and fifty participants were included. Baseline characteristics, data on exercise, outdoor activities, and access to foods and blood chemistries, including hemoglobin A1C (A1C) and fasting plasma glucose (FPG), were reviewed, and collected from electronic medical records before and after the COVID-19 pandemic. Results: There was a significant increase in mean A1C (g/L) ± SD (74.8 ± 13.7 vs. 76.0 ± 15.3, p-value <0.016), the mean duration of outdoor activities (hours/day) ± SD during the COVID-19 virus pandemic was significantly decreased. (5.35 ± 4.48 vs. 4.03 ± 4.37, p-value <0.001) Conclusion: The present study showed that mean A1C was significantly increased during the COVID-19 virus pandemic. Nevertheless, a statistical difference was not observed in FPG. The impact of quarantine, social distancing, and community containment during the epidemic on lifestyles may be the essential factor in increasing A1C.

Published: October 2021

O pequeno comerciante explora inúmeros recursos para vender um produto, como pregões, linguagem corporal, elementos parodísticos, poesia oral, cantos e sons ritmados, artifícios verbais, entonação de voz e linguagem estilizada. O objetivo do presente estudo é comentar descrições de vendedores ambulantes, cantos e pregões de rua como objetos culturais em textos memorialísticos. Considerando tal propósito, neste artigo o conceito de objeto cultural se define em comparação com a ideia de “lugares da memória”, termo cunhado por Pierre Nora (1989) e com a noção antropológica de “traços”, desenvolvida por Jean-Yves Boursier. A análise mostra que relatos históricos, literários e memorialísticos registram a imagem de vendedores de rua e pregões destacando aspectos mnemônicos, pitorescos e sociais.
