Antioxidants in Flour of the Oilseed Crop Camelina sativa (L.) Crantz
Authors: Russo Roberto , Reggiani Remo
Published: July 2018

Forty-seven accessions of Camelina sativa (L.) Crants (41 spring and 6 winter forms) were analyzed for antioxidant activity, total phenolic content (TPC), flavonoids and proanthocyanidins. The antioxidant activity (AA%) was high in camelina accessions and with a significant variability among accessions and between spring and winter forms. The highest antioxidant activities have been observed in some spring accessions (CAM35, CAM173 and CAM268). TPC was high in camelina and significantly different among accessions. Antioxidant activity resulted highly correlated with TPC, while no correlation was observed with flavonoid and proanthocyanidin contents. Significant variability was observed among accessions but not between groups (winter and spring) for flavonoid and proanthocyanidin contents. These two classes of compounds showed a significant inverse correlation between them suggesting that their synthesis is in competition. The camelina cake can enrich the animal diet of antioxidant compounds (phenolics) and some spring accessions are more promising for future breeding programs.
A comparison between video otoscopy and standard tympanometry findings in adults living with human immunodeficiency virus (HIV) in South Africa
Authors: Sebothoma Ben , Khoza-Shangase Katijah
Published: July 2018

Background: Literature suggests that there is a correlation between video otoscopy and standard tympanometry findings. However, there is limited evidence on whether these two measures are comparable in the identification of middle ear pathologies in adults living with human immunodeficiency virus (HIV). Objective: This study aimed to determine the correlation between video otoscopy and standard tympanometry with 226 Hz probe tone in the identification of middle ear pathologies in adults living with HIV in Limpopo, South Africa. Method: A prospective, non-experimental, comparative design was employed on HIV-positive adults aged 18 years and older. All participants underwent basic audiological assessment including case history interviews, video otoscopy, tympanometry with a 226 Hz probe tone and pure tone audiometry. Two ear, nose and throat (ENT) specialists independently analysed video otoscopic images and provided their reports to the researcher, and these were compared to the tympanometry results. The IBM SPSS v.24 was used for data analysis, including the use of Cohen’s kappa to determine the agreement between the two procedures. Pearson’s correlation coefficient was used to determine the strength of the correlation between tympanometry and video otoscopy. Results: A total of 87 adults (N = 161 ears) took part in the study. Middle ear pathology was observed in 8% (n = 13) of the sample when tympanometry was used, and this increased to 10.6% (n = 17) when video otoscopy was utilised. Kappa statistics found a good agreement (k = 0.7) between the diagnoses made by two ENTs. However, there was poor agreement (k = 0.2) between the diagnoses by video otoscopy and tympanometry. Pearson’s correlation coefficient indicated weak correlation between video otoscopy and tympanometry (r = 0.195). Conclusion: Findings from this study suggest that video otoscopy may be more accurate in the identification of middle ear pathologies in adults living with HIV when compared to tympanometry. These findings have training implications in the use of video otoscopy to ensure accuracy and reliability. Clinical implications of current findings include the use of both video otoscopy and tympanometry in a complementary manner for more sensitive identification of middle ear pathologies in this population. Lastly, tele-audiologic implications of the use of video otoscopy to increase access in resource-constrained contexts are raised.
Spectrum theory of second-order difference equations with indefinite weight
Authors: Ma Ruyun , Gao Chenghua , Lu Yanqiong
Published: July 2018

In this paper, we study the spectrum structure of second-order difference operators with sign-changing weight. We apply the Sylvester inertia theorem to show that the spectrum consists of real and simple eigenvalues; the number of positive eigenvalues is equal to the number of positive elements in the weight function, and the number of negative eigenvalues is equal to the number of negative elements in the weight function. We also show that the eigenfunction corresponding to the

Carbon emission effect of urbanization at regional level: empirical evidence from China
Authors: Niu Honglei , Lekse William
Published: July 2018

Historically, global urbanization has been an essential ingredient for national economic growth and beneficial social transformation. However, with the global urban population currently generating two-thirds of all carbon emissions, global policymakers are urging mayors and regional leaders to make difficult decisions to reduce the negative impacts of urbanization on the environment. The authors begin their examination of the implications of local and regional factors by applying the Dynamic Spatial Durbin Panel Data Model to empirically examine aspects of developing low-carbon strategies for the rapidly expanding size and number of the world’s urban areas. The results indicate that the contribution of urbanization to carbon emissions can be positively affected when regional policy makers collaborate to focus on spillover effects to simultaneously manage the scope, diversity, and complexity of economic and environmental issues from the perspective of creating a balance between rapid urbanization and relevant regional factors. Regional leaders can make a difference by creating both short-term goals and long-term strategies for maintaining low-carbon urbanization, nurturing regional coordination, monitoring and managing eco-friendly regional spillover effects, supporting low-carbon technology innovations, and maintaining optimal city size.
Partitioning the primary ice formation modes in large eddy simulations of mixed-phase clouds
Authors: Hande Luke B. , Hoose Corinna
Published: July 2018

Abstract. State-of-the-art aerosol-dependent parameterisations describing each heterogeneous ice nucleation mode (contact, immersion, and deposition ice nucleation), as well as homogeneous nucleation, were incorporated into a large eddy simulation model. Several cases representing commonly occurring cloud types were simulated in an effort to understand which ice nucleation modes contribute the most to total concentrations of ice crystals. The cases include a completely idealised warm bubble, semi-idealised deep convection, an orographic cloud, and a stratiform case. Despite clear differences in thermodynamic conditions between the cases, the results are remarkably consistent between the different cloud types. In all the investigated cloud types and under normal aerosol conditions, immersion freezing dominates and contact freezing also contributes significantly. At colder temperatures, deposition nucleation plays only a small role, and homogeneous freezing is important. To some extent, the temporal evolution of the cloud determines the dominant freezing mechanism and hence the subsequent microphysical processes. Precipitation is not correlated with any one ice nucleation mode, instead occurring simultaneously when several nucleation modes are active. Furthermore, large variations in the aerosol concentration do affect the dominant ice nucleation mode; however, they have only a minor influence on the precipitation amount.
Technical note: Updated parameterization of the reactive uptake of glyoxal and methylglyoxal by atmospheric aerosols and cloud droplets
Authors: Curry Leah A. , Tsui William G. , McNeill V. Faye
Published: July 2018

Abstract. We present updated recommendations for the reactive uptake coefficients for glyoxal and methylglyoxal uptake to aqueous aerosol particles and cloud droplets. The particle and droplet types considered were based on definitions in GEOS-Chem v11, but the approach is general. Liquid maritime and continental cloud droplets were considered. Aerosol types include sea salt (fine and coarse), with varying relative humidity and particle size, and sulfate/nitrate/ammonium as a function of relative humidity and particle composition. We take into account salting effects, aerosol thermodynamics, mass transfer, and irreversible reaction of the organic species with OH in the aqueous phase. The new recommended values for the reactive uptake coefficients in most cases are lower than those currently used in large-scale models, such as GEOS-Chem. We expect application of these parameterizations will result in improved representation of aqueous secondary organic aerosol formation in atmospheric chemistry models.
Validation and application of optimal ionospheric shell height model for single-site TEC estimation
Authors: Zhao Jiaqi , Zhou Chen
Published: July 2018

Abstract. We recently proposed a method to establish optimal ionospheric shell height model based on the international GNSS service (IGS) station data and the differential code bias (DCB) provided by Center for Orbit Determination in Europe (CODE) during the time from 2003 to 2013. This method is very promising for DCB and accurate total electron content (TEC) estimation by comparing to traditional fixed shell height method. However, this method is basically feasible only for IGS stations. In this study, we investigate how to apply the optimal ionospheric shell height derived from IGS station to non-IGS stations or isolated GNSS receivers. The intuitional and practical method to estimate TEC of non-IGS stations is based on optimal ionospheric shell height derived from nearby IGS stations. To validate this method, we selected two dense networks of IGS stations located in US and Europe region. Two optimal ionospheric shell height models are established by two reference stations, namely GOLD and PTBB, which are located at the approximate center of two selected regions. The predicted daily optimal ionospheric shell heights by the two models are applied to other IGS stations around these two reference stations. Daily DCBs are calculated according to these two optimal shell heights and compared to respective DCBs released by CODE. The validation results of this method present that 1) Optimal ionospheric shell height calculated by IGS stations can be applied to its nearby non-IGS stations or isolated GNSS receivers for accurate TEC estimation. 2) As the distance away from the reference IGS station becomes larger, the DCB estimation error becomes larger. The relation between the DCB estimation error and the distance is generally linear.
The Effect of the 2013–2016 High Temperature Anomaly in the Subarctic Northeast Pacific (The “Blob”) on Net Community Production
Authors: Yang Bo , Emerson Steven R. , Peña M. Angelica
Published: July 2018

Abstract. A large anomalously warm water patch (the “Blob”) appeared in the NE Pacific Ocean in the winter of 2013–14 and persisted through 2016 causing strong positive upper ocean temperature anomalies at Ocean Station Papa (OSP, 50° N, 145° W). The effect of the temperature anomalies on annual net community production (ANCP) was determined by upper ocean chemical mass balances of O2 and DIC using data from a profiling float and a surface mooring. Year-round oxygen mass balance in the upper ocean (surface to 91–111 m) indicates that ANCP decreased after the first year when warmer water invaded this area and then returned to the “pre-blob” value (2.4, 0.8, 2.1, and 1.6 mol C m−2 yr−1 with a mean value of 1.7 ± 0.7 mol C m−2 yr−1). ANCP determined from DIC mass balance has a mean value that is similar within the errors as that from the O2 mass balance but without significant trend (2.0, 2.1, 2.6, and 3.0 mol C m−2 yr−1 with a mean value of 2.4 ± 0.6 mol C m−2 yr−1). This is likely due to differences in the air-sea gas exchange, which is a major term for both mass balances. Oxygen has a residence time with respect to gas exchange of about one month while the CO2 gas exchange response time is more like a year. Therefore the biologically induced oxygen saturation anomaly responds fast enough to record annual changes whereas that for CO2 does not. Phytoplankton pigment analysis from the upper ocean show lower chlorophyll-a concentrations and greater relative abundance of picoplankton in the year after the warm water patch entered the area than in previous and subsequent years. Our analysis of multiple physical and biological processes that may have caused the ANCP decrease after warm water entered the area suggests that it was most likely due to changes in plankton community composition.
Influence of concurrence of extreme drought and heat events on carbon and energy fluxes in dominant ecosystems in the Pacific Northwest region

Published: July 2018

Abstract. The impacts of drought intensities and vapor pressure deficits (VPD) beyond historic norms in Pacific Northwest (PNW), USA, are critical in understanding the potential future function and resilience of ecosystems in the region. While ecosystems in this region are adapted to seasonal droughts, June 2015 temperatures were the highest recorded in the region and strongly coupled with relatively low soil moisture. June is usually the best month for growth in the PNW. Here, we examined the impact of the June 2015 climate extremes on carbon and energy fluxes at sagebrush in the high desert, young and mature ponderosa pine in the semi-arid Great Basin, and Douglas-fir in the mesic Coast Range ecoregion compared to an average climate year (2014). We assessed if the ecosystems recover from extreme climate stress within the growing season. The monthly anomalies in temperature and VPD were 3 standard deviations, and precipitation was 1 standard deviation, outside the 30-year mean at all sites. In sagebrush, the carry-over effect of precipitation (i.e., intensive precipitation prior to the drought and heat) mitigated the immediate impact of extreme climate stress, leading to 25–40 % increase in net ecosystem production (NEP) and gross primary production (GPP), with little change in ecosystem respiration (RE) and 65 % increase in latent heat flux, compared to the June 2014. The drought and heat lowered NEP by 35–65 % and GPP by 15–33 % in ponderosa pine and Douglas-fir. A greater increase in latent heat flux was observed in Douglas-fir (110 %) than in ponderosa pine (
Use of an external organic carbon source in the removal of nitrates in bio-sand filters (BSFs)
Authors: Mutsvangwa Crispen , Matope Evans
Published: July 2018

Abstract. Bio-sand filters (BSFs) are point-of-use (POU) potable water filtration systems commonly used in low-income communities at household level. The principle of operation is similar to that of a slow sand filter and the major difference is that they are operated intermittently at the POU. It is one of the emerging low-cost technologies which makes use of readily and locally available construction materials but is poor in the removal of nitrates. In order to enhance the removal of nitrates through denitrification, a modified BSF with ethanol as an external carbon source at C  /  N ratios of 1.1 and 1.8 was investigated. In the absence of an external carbon source, the nitrate removal efficiency was 32 %, whilst removal efficiencies at C   /   N ratios of 1.1 and 1.8 were 44 and 53 % respectively. The inflow rate reduced significantly from an initial flow rate of 0.04 to 0.01 m3 h−1. The reduction in the inflow rate was mainly due to the growth of the biological layer on the filter media. The study showed that the use of an external carbon source like ethanol in bio-sand filtration enhances the removal of nitrates in potable water.
Variations of future precipitations in Poyang Lake Watershed under the global warming using a spatiotemporally distributed downscaling model
Authors: Zhang Ling , Chen Xiaoling , Lu Jianzhong , Liang Dong
Published: July 2018

Abstract. Traditional statistic downscaling methods are processed on independent stations, which ignores spatial correlations and spatiotemporal heterogeneity. In this study, a spatiotemporally distributed downscaling model (STDDM) was developed. The method interpolated observations and GCMs (Global Climate Models) simulations to continual finer grids; then created relationship, respectively for each grid at each time. We applied the STDDM in precipitation downscaling of Poyang Lake Watershed using MRI-CGCM3 (Meteorological Research Institute Coupled Ocean-Atmosphere General Circulation Model3), with an acceptant uncertainty of ≤ 4.9 %, and created future precipitation changes from 1998 to 2100 (1998–2012 in the historical and 2013–2100 in RCP8.5 scenario). The precipitation changes showed increasing heterogeneities in temporal and spatial distribution under the future climate warming. In the temporal pattern, the wet season precipitation increased with change rate (CR) = 7.33 mm/10a (11.66 mm/K) while the dry season precipitations decreased with CR = −0.92 mm/10a (−4.31 mm/K). The extreme precipitation frequency and intensity were enhanced with CR = 0.49 days/10a and 7.2 mm•day-1/10a respectively. In the spatial pattern, precipitations in wet or dry season showed an uneven change rate over the watershed, and the wet or dry area exhibited a wetter or drier condition in the wet or dry season. Analysis with temperature increases showed precipitation changes appeared significantly (p
Melting and fragmentation laws from the evolution of two large Southern Ocean icebergs estimated from satellite data
Authors: Bouhier Nicolas , Tournadre Jean , Rémy Frédérique , Gourves-Cousin Rozenn
Published: July 2018

Abstract. The evolution of
the thickness and area of two large Southern Ocean icebergs that have drifted
in open water for more than a year is estimated through the combined analysis
of altimeter data and visible satellite images. The observed thickness
evolution is compared with iceberg melting predictions from two commonly used
melting formulations, allowing us to test their validity for large icebergs.
The first formulation, based on a fluid dynamics approach, tends to
underestimate basal melt rates, while the second formulation, which considers
the thermodynamic budget, appears more consistent with observations.
Fragmentation is more important than melting for the decay of large icebergs.
Despite its importance, fragmentation remains poorly documented. The
correlation between the observed volume loss of our two icebergs and
environmental parameters highlights factors most likely to promote
fragmentation. Using this information, a bulk model of fragmentation is
established that depends on ocean temperature and iceberg velocity. The model
is effective at reproducing observed volume variations. The size distribution
of the calved pieces is estimated using both altimeter data and visible
images and is found to be consistent with previous results and typical of
brittle fragmentation processes. These results are valuable in accounting for
the freshwater flux constrained by large icebergs in models.
“Teen Views of Sex:” Inter-animation of dialogues in a radio feature story produced by Mexican immigrant youth
Authors: Walker Dana
Published: July 2018

This paper proposes an analysis of dialogical processes in the creation of a radio feature story titled “Teen Views of Sex,” co-produced by Mexican immigrant high school students in the context of a Youth Radio and Radio Arts program. After describing the socio-cultural and curricular context of the program, I apply Zittoun and Grossen’s (2013) semiotic approach to dialogicality to describe the kinds of dialogue that took place during the interviews and subsequent reflections upon the feature story and production process. The types of dialogue examined include: actual dialogue, distant dialogue, auto-dialogue, dialogue between situations, and dialogue with material objects, or non-human actants. I explore how the inter-animation of these forms of dialogue gave rise to dialogic tensions, which may have created openings for shifts in identity positioning and an enhanced sense of agency for the youth in their personal and public lives.
Rearticulando o conceito de dispositivo: combinando STS e analítica do governo
Authors: Lemke Thomas
Published: July 2018

Este artigo elucida, em primeiro lugar, os vários significados da noção francesa de dispositif e contrasta-a com os usos de “aparelho” (“appareil”), por um lado, e “reunião” (“agencement”), por outro. A segunda parte apresenta o uso distintivo de Foucault do conceito de dispositivo. O argumento baseia-se na tese de que a noção de dispositivo de Foucault está firmemente ancorada em uma analítica do governo, na medida em que se concentra na direção e regulação de forças agenciais e processos vitais. Na última parte, proponho combinar uma analítica do governo, seguindo Foucault, com insights dos Estudos de Ciência e Tecnologia (STS). Argumentoque essa síntese teórica entre STS e uma analítica do governo ajuda a corrigir os problemas de muitas análises da sociologia política e da teoria social e política ao enfrentar as transformações e mudanças nas sociedades contemporâneas.

Published: July 2018

El enfoque de los «mecanismos causales» ayuda a identificar el poder causal de los distintos factores que intervienen en una política concreta y a definir la configuración de elementos que produce un determinado resultado. Este enfoque se aplica al caso del programa URBANA (2007- 2013) de Alcalá de Guadaíra (España), que presenta un incremento significativo de la participación social en comparación con los demás municipios que participaron en el programa. A partir de su estudio, se realiza un ejercicio de construcción teórica dirigido a descubrir los mecanismos causales que han desencadenado este resultado, pensando en su posible transferibilidad. Para la selección del caso, se ha aplicado una metodología cuantitativa, mientras que para la identificación de los mecanismos causales se han realizado entrevistas en profundidad a diversos actores implicados en la iniciativa.
Speaking Activities to Foster Students’ Oral Performance at a Public School
Authors: Carolina Bocanegra Bonilla , Astrid Ramirez Valencia
Published: July 2018

By employing an action research framework, this study was designed to explore the effectiveness of a set of speaking activities centered on a children’s cartoon to improve oral performance in the EFL classroom. The participants were fourth graders of a public school in Colombia, who had low oral performance in spoken English language. The findings suggest that the proposed speaking activities were comprehensible for the students, and appropriate to the students’ proficiency level. Although to maximize learners’ opportunities to speak in the classroom, teachers should design activities that provide chances to talk in English. Thus students will be engaged to participate in the classroom. Also, most of the students were comfortable speaking during the activities since they were familiar with watching cartoons, thus being at ease with certain topics can help students exchange ideas in class. The most important recommendation is to avoid translating instruction into students’ mother tongue for the purpose to familiarize students with the target language.
The Effect of Saturated Fat Intake With Risk of Stroke and Coronary Heart Disease: A Systematic Review of Prospective Cohort Studies
Authors: Al Shamsi Hilal , Almutairi Abdullah
Published: July 2018

BACKGROUND: A decline in saturated fat intake has generally been thought to improve cardiovascular health.OBJECTIVE: The objective of this review is to summarize the evidence presented in recent prospective epidemiologic studies related to the association of saturated fat intake and risk of stroke and coronary heart disease (CHD).DESIGN: Sixteen prospective cohort studies identified by searches of the Medline and ProQuest databases are included in this review. The association of saturated fat intake with stroke and CHD risk is explored using the relative risk (RR), Hazard ratio (HR), and 95% confidence interval (CI) methods.RESULTS: Over follow-up periods of 8 to 30 years, 22,773 of 668,082 participants of these 16 studies developed stroke or CHD. Saturated fat intake was associated with an increased risk of CHD (HR = 2.36, 95% CI 1.10–5.09) but not with stroke. Gender and age had no impact on the stroke rate, whereas the female gender was a risk factor for CHD (HR = 3.07, 95% CI 1.54–6.11). In addition, a subgroup analysis showed a positive association between smoking history and increasing risk of stroke and CHD.CONCLUSION: This systematic review of prospective-cohort epidemiologic studies found that there is a weak to strong association between saturated fat intake and increased CHD risk but not significant evidence for concluding that saturated fat intake is associated with an increased risk of stroke. In addition, more research is needed to determine whether risk of stroke and/or CHD is potentially affected by specific nutrients used to replace saturated fat.

The sixth season of fieldwork of the Tell el-Retaba Archaeological Mission has brought a number of significant results. For the first time remains of a Hyksos settlement (beside the previously known cemetery) were uncovered. Exploration of a large, regularly planned building, divided into a number of standardized flats, brought new evidence for the reconstruction of the function and organization of a strongly fortified town, which existed on the site during the Twentieth Dynasty. Remains of a Third Intermediate Period settlement showed that after the New Kingdom there was a clear change in the settlement pattern in Tell el-Retaba.
Saqqara 2012: the pottery
Authors: Rzeuska Teodozja I.
Published: July 2018

The pottery analyzed this season was associated with the Lower Necropolis (areas
of Chapel 14 of Ikhi/Mery and Chapel 13) from the late Old Kingdom as well as the Upper
Necropolis from the Late through Roman periods, extant in this region. The assemblage from the
Lower Necropolis supplemented the little known ceramic repertoire from the Saqqara phase II
(Pepi I–Merenre). Of interest is a type of miniature vessel possibly connected with child burials.
As for pottery from the Upper Necropolis, the form repertoire indicates that the area currently
explored was the site of simple embalming caches.

In the course of two seasons in 2012 and 2013 the team carried out excavations and
research on the living quarters alongside the fortifications of Banganarti, including a large building
(E.1) and eastern tower. Work on the restoration/conservation of the Upper Church progressed
according to plan, combined with limited iconographic studies. The team also worked at the sites
of Selib and Soniyat. At Selib explorations continued at three locations. The phasing of the church
at Selib 1 was established (separate report by A. Cedro), leading to a reconstruction of the plan
of the earliest two buildings. A Meroitic(?) structure was investigated at Selib 3 and the Meroitic
settlement at Selib 2 continued to be investigated (separate report by R. Hajduga and K. Solarska).
A tachymetric plan and magnetic map of the environs of the Kushite temple at Soniyat was
accomplished, recording a huge building (palace?) of apparently Kushite date (Napatan ceramic
forms and Egyptian imports dating from the Third Intermediate Period) to the north of the temple.
A separate team undertook a reconnaissance in regions scheduled to be flooded due to new dam
construction projects in Kajbar and Shereik (Third and Fifth cataracts), staying on to record in
detail a number of Makurian fortresses.

the burial chamber and two lateral chambers. The number of bones from T.21 was much smaller,
restricted to 78 fragments, coming mostly from the burial chamber. Except for one bird bone and
seven unidentified fragments, the remains belonged to an ovicaprid. Marks visible on the bones
from both tumuli confirmed that the parts of cattle and ovicaprine carcasses served as food offerings
for the dead.
Preliminary results of a stratigraphic analysis of late Roman and
early Byzantine architecture in the residential quarter of Jiyeh
Authors: Dzik Michał
Published: July 2018

The paper discusses the results of the first season of research undertaken to establish and
document the architectural stratification of the residential quarter in Jiyeh (ancient Porphyreon).
The research was started on a separate complex of 14 rooms. Three phases of building development
in the late Roman and early Byzantine periods were distinguished. Evidence was found of
the division of this complex into three houses. Remains of stairways identified in two of the houses
proved the existence of double-storey buildings. In the northern house of the complex, the layout
of recesses and corbels preserved in the walls suggests the presence of a wooden gallery, communicating
at ground level with rooms on the upper floor. This paper presents also some preliminary
remarks on the functional division of the houses.
Levallois Tradition epigones in the Middle Nile Valley:
survey in the Affad Basin
Authors: Osypińska Marta , Osypiński Piotr
Published: July 2018

The paper presents the results of an archaeological ground survey aimed to record
prehistoric settlement landscape in chosen parts of the Southern Dongola Reach (Tergis, Affad
and El-Nafab districts). The project fills in the gaps in earlier research on the right bank of the
Nile. Numerous new sites were recorded, all reflecting a frequently occupied level of silts and sands
originating in the former river valley aggradations. Prospection of locations recorded in 2003 and
later demonstrated also the progressing destruction of archaeological sites on the fringes of modern
settlement and the new road from Karima to Nawa.
The solar altar in the Temple of Hatshepsut at Deir el-Bahari: architecture and ideology
Authors: Ćwiek Andrzej
Published: July 2018

In a recent article Teresa Dziedzic presented a theoretical reconstruction of the solar altar in the Temple of Hatshepsut at Deir el-Bahari, with two obelisks standing on the top of it. From both a technological/logistic and an ideological point of view this hypothesis seems untenable. An alternative reconstruction may be offered in agreement with the archaeological evidence and the ideological program of the temple. Statues of the king and of Amun-Ra placed on the altar served as focal points of an early version of the ritual of ‘joining the sun-disk’.
Faience objects from the Tomb MMA 1152 at Sheikh Abd el-Gurna
Authors: Chudzik Patryk , Ćwiek Andrzej
Published: July 2018

Excavations in the area of tomb MMA 1152 at Sheikh Abd el-Gurna, conducted since 2003, have uncovered a substantial set of faience objects coming from burials made there during the later Pharaonic Period, before the tomb became a hermitage for Coptic monks. Analysis of the material points to several episodes of reuse of the original Middle Kingdom structure in the Third Intermediate Period and the Late Period.
Monetization of Roman Egypt during the Flavian Dynasty (AD 69–96): the case of Alexandria and Berenike
Authors: Lach Katarzyna
Published: July 2018

A study of coin output in Egypt during the Flavian dynasty (AD 69–96) brings to light a dichotomy in circulation between billon tetradrachms and low denomination bronze coins. The composition of hoards with Flavian silver issues suggests minimal coin production due to a sufficient quantity of Nero’s tertadrachms on the market. However, stray finds of coins from the Flavian dynasty consist mainly of bronze issues, apparently outnumbering Nero’s low-denomination coin output. A tempting idea to consider is that the low number of Flavian silver coins in circulation resulted in an extended production of bronze issues.
Preliminary report on Polish excavations at Marina el-Alamein
in the 2012–2015 seasons
Authors: Jakubiak Krzysztof
Published: July 2018

The Marina el-Alamein Archaeological Project concentrated on excavating the area in
the northern part of the harbor town, where a street (S1) existed, running north–south toward the
harbor, lined by buildings on both sides. A test trench was dug across it to study the stratigraphy.
It helped to identify several street levels and at least two major building phases in this area. One of
the structures (H39) contained a hypocaust furnace that led to the building interpreted as a bathhouse.
A pebble mosaic was uncovered immediately west of the furnace. Opposite Building H39
and across street S1, there was a large and richly furnished residential house (H42). It encompassed
two paved courtyards, which were in use in the first half of the 2nd century AD. Three seasons of
excavations (2012, 2013 and 2014) were followed by a season devoted in its entirety to documentation
of the pottery and other small finds from the excavations and checking of the documentation
from earlier seasons.
Research and conservation in Marina el-Alamein in 2014 and 2015 (Polish–Egyptian Conservation mission). Part two: The Hellenistic Baths

Published: July 2018

In 2014 and 2015, the Polish–Egyptian Conservation Mission to Marina el-Alamein
undertook research, conservation and presentation of the area north of the central square of the
ancient town. A major landmark in this part of the city are the public baths from the Hellenistic
period, discovered in 1987. The work was focused on the main chambers of the bath: the central tholos with relics of hip-bathtubs, the neighboring room with an immersion bathtub, and a set of rooms in the southern area of the complex.
Four seasons of documentation in the Main Sanctuary of Amun-Re in the Temple of Hatshepsut at Deir el-Bahari
Authors: Pawlicki Franciszek
Published: July 2018

Four seasons of documentation have supplied pertinent data to indicate that the Main Sanctuary of Amun-Re in the Temple of Hatshepsut in Deir el-Bahari was perceived from a theological perspective as a cult place for the local form of Foremost of +sr-Dsrw and for the royal worship of Hatshepsut connected with it. The latter aspect was of sufficient significance to warrant twice a far-going modification of the decoration of the tympanum of the east wall of the Bark Hall, influencing the way the Inner Sanctuary was illuminated.
Archaeological fieldwork in Berenike in 2014 and 2015: from Hellenistic rock-cut installations to abandoned temple ruins

Published: July 2018

The report brings a comprehensive summary of archaeological fieldwork and survey carried out in Berenike on the Red Sea coast of Egypt and in the Eastern Desert hinterland over the course of two seasons in 2014 and 2015. The completed magnetic map of the site is discussed in some detail, assessing the potential for future excavations. The report covers the most important discoveries of the two seasons, which include fragments of Middle Kingdom Pharaonic stelae, possibly pushing back the foundation of the harbor, archaeological evidence of a rock-cut watercollection system forming part of the Hellenistic-age fortifications and two inscribed stone bases, one of which records a secretary of an aromatics warehouse at Berenike, discovered undisturbed in the courtyard of the Great Temple of Berenike (also called the Serapis Temple). A previously unknown religious(?) complex was discovered on the western outskirts of the site thanks to work with Corona satellite imagery. In turn, analysis of the magnetic mapping of the city revealed an administrative(?) complex in the northern part of the town; the later, 5th and 6th century layers were examined inside a chamber with niche forming part of this complex. Work also continued in the early Roman harbor, uncovering among others a complete timber ship frame, and a collection of garnets in subsidiary buildings in the late Roman temenos located in the entrance to the southwestern bay.
Banganarti and Selib in the 2013/2014 and 2014/2015 seasons with Appendix 1: Pottery from Selib. Preliminary report (2013/2014 and 2014/2015 seasons), Appendix 2: Osteoarchaeological analyses of skeletal material from Selib 1 and Banganarti (2013/2014 and 2014/2015 seasons)
Authors: Żurawski Bogdan , Cedro Aneta , Bury Magdalena
Published: July 2018

The Polish archaeological project excavating at the Nubian sites of Banganarti and Selib concentrated on uncovering domestic architecture: the northeastern and southwestern districts at medieval Christian Banganarti and selected houses of Meroitic date at Selib 2. The conservation and restoration program put the finishing touches on the Raphaelion church in Banganarti and did substantial work on the remains of the earlier churches. The oldest church from Selib 1 was investigated and dated to the 6th–7th century based on a study of a well stratified ceramic assemblage. Pottery from the northern and southern refuse dumps ranged in date from the 9th to the 12th/13th century. A group of liturgical vessels, containing mostly small juglets and chalices, was distinguished in this assemblage. Exploration of the earlier Northern Building revealed pottery
contemporaneous with the earliest phase of the church on site. Anthropological research was carried out on skeletal remains from the medieval cemeteries of Selib 1 and from individual graves at Banganarti. The results of ceramic studies and of the anthropological examination are reported in separate appendices to the main report.
Early Makuria Research Project: Interim report on the excavation at el-Detti in 2014 and 2015 with Appendix: Metal objects from the el-Detti cemetery
Authors: El-Tayeb Mahmoud , Czyżewska-Zalewska Ewa , Kowarska Zofia , Lenarczyk Szymon
Published: July 2018

Burial structures and the assemblages found inside them at the site of el-Detti, about 13 km downstream from Karima and 7 km upstream from el-Zuma, were explored in 2014 and 2015 by a joint team from the Polish Centre of Mediterranean Archaeology University of Warsaw and the National Corporation for Antiquities and Museums of Sudan. The aim was to enable comparison with the excavated burials at el-Zuma, a nearby tumuli field explored by the Early Makuria Research Project in recent years. Special attention was paid to metal artifacts from the tombs (studied in the appendix), which contribute to a better understanding of the local social and cultural traditions. The focus of the Early Makuria Research Project on examining the mortuary customs at el-Detti has helped to identify the burial practices of Early Makurian society and to trace the spread of Early Makurian society over time.
Plant remains from Jiyeh/Porphyreon, Lebanon (seasons 2009–2014): preliminary results of archaeobotanical analysis and implications for future research
Authors: Badura Monika , Rzeźnicka Ewelina , Wicenciak Urszula , Waliszewski Tomasz
Published: July 2018

The seaside settlement of Jiyeh in Lebanon, now identified with the ancient Porphyreon, boasts a history dating back to the Late Bronze Age and Iron Age when Phoenicia occupied part of the Levantine coast (eastern Mediterranean). Extensive archaeological excavations by a team from the Polish Centre of Mediterranean Archaeology University of Warsaw have focused on the urban residential quarter, which consists of numerous houses and buildings separated by passages, containing material that has provided important insights into the lives of its inhabitants over time. However, as archaeobotanical studies had not been conducted there before, the question of plant use remains an important and largely unknown area of research. This article presents the first botanical results from Jiyeh (seasons 2009–2014) and considers their implications for future cooperation between archaeologists and natural scientists.
