Telehealth service delivery for persons with alcoholism
Authors: Frueh B Christopher , Henderson Scott , Myrick Hugh
Published: July 2017

Videoconferencing at a bandwidth of 384 kbit/s was used in open sessions for subjects with alcohol use disorders (AUD). Study participants received eight sessions of group therapy over a four-week period from an accredited addictions counsellor. Outcome assessment included self-report measures, a qualitative interview and a chart review. Of the 18 subjects who started the study, 14 attended at least four sessions of therapy, completed self-report assessments and the thematic interview. The participants reported high levels of satisfaction with telepsychiatry, found the intervention to be highly credible, had good session attendance and attrition comparable to that expected with conventional same-room treatment. In all, 82% of subjects reported that they would recommend the service to a friend or family member. The results demonstrate the feasibility of using videoconferencing for service delivery to adults with AUD, and encourage the future performance of randomized controlled trials.
Experimental study on reinforced concrete frames with two-side connected buckling-restrained steel plate shear walls
Authors: Liu Wen-Yang , Li Guo-Qiang , Jiang Jian
Published: July 2017

This article experimentally studies the seismic behavior of reinforced concrete frames with buckling-restrained steel plate shear walls. The buckling-restrained steel plate shear wall is connected to adjacent reinforced concrete beams alone by an embedded steel connector in the beams (two-side connection). This is to avoid the force transfer between the shear wall and adjacent columns with a four-side connection. Four specimens of two-story and one-bay reinforced concrete frames with buckling-restrained steel plate shear walls are designed and tested under monotonic and cyclic loads. Finite element analyses are also conducted to further investigate the advantages of buckling-restrained steel plate shear walls by comparing the behavior of reinforced concrete frames with and without buckling-restrained steel plate shear walls. The results show that the presence of buckling-restrained steel plate shear wall can not only enhance the stiffness and load-bearing capacity but also improve the ductility and energy dissipation capacity of reinforced concrete frame structures. It is found that the drift ratio of the specimens reaches 1/15 under monotonic loads and 1/30 under cyclic loads. The specimens have ductility coefficients greater than 10. Two failure modes are found for reinforced concrete frames with buckling-restrained steel plate shear walls. Damages may concentrate at the base of ground floor columns for a frame with strong connectors, while plastic hinges may form at the ends of beams and columns for frames with weak connectors.
Reporting medical device safety incidents to regulatory authorities: An analysis and classification of technology-induced errors
Authors: Palojoki Sari , Saranto Kaija , Lehtonen Lasse
Published: July 2017

The European Union Medical Device Directive 2007/47/EC1 defines software with a medical purpose as a medical device. The implementation of health information technology suffers from patient safety problems that require effective post-market surveillance. The purpose of this study was to review, classify and discuss the incident data submitted to a nationwide database of the Finnish National Competent Authority with other forms of data. We analysed incident reports submitted to the authority database by users of electronic health records from 2010 to 2015. We identified 138 valid reports. Adverse events associated with electronic health record vulnerabilities, clustered around certain error types, cause serious harm and occur in all types of healthcare settings. The low rate of reported incidents raises questions about not only the challenges associated with medical software oversight but also the obstacles for reporting.
Offline ‘stranger’ and online lurker: methods for an ethnography of illicit transactions on the darknet
Authors: Ferguson Rachael-Heath
Published: July 2017

In 2011, the illicit online marketplace ‘Silk Road’ opened for business. Located on the darknet, accessed via the Tor browser, Silk Road was the first of a new breed of darknet marketplaces (DNMs) and smartphone app-based drug markets. Participants on these transact under closely guarded aliases using sophisticated encryption. This article examines how ethnographers might study DNMs and the app-based drug trade. I spent over four years observing and interacting on these marketplaces and associated chat forums, following offline participant observation in a variety of criminal markets which provide useful methodological comparison to the DNM and smartphone app fieldwork sites. This article discusses my methods, highlights differences in online versus offline ethical concerns and risks, and I make suggestions to further the development of a formal methodology for digital ethnography of criminal and hidden online populations.
Ultra-low-power media access control protocol based on clock drift characteristics in wireless sensor networks
Authors: Pak Wooguil
Published: July 2017

Many researchers have analyzed sources of uncertainty in synchronization protocols for wireless sensor networks. However, very few researchers perform this work in depth, and failed to discover comprehensive characteristics since they worked with only one or two measurement intervals. To overcome this problem, extensive measurements were conducted and analyzed to find the characteristics of the sources according to various measurement intervals. Using the characteristics, a new media access control protocol, WideMAC, was designed to support a wide range of duty cycles for various applications. The transmission node in WideMAC calculates the wakeup time of the reception node before transmitting a packet and adaptively estimates the synchronization error size according to the synchronization interval from seconds to hours. To track the reception node’s wakeup time for synchronization, WideMAC uses two estimation algorithms that estimate the wakeup time and the upper bound of the total timing error. Accurate estimation of the wakeup time results in a significant amount of energy saving at the transmission node. Finally, through extensive performance evaluations in a testbed, WideMAC confirmed that it can significantly outperform existing state-of-the-art protocols.
Leader perceptions and motivation as outcomes of followership role orientation and behavior
Authors: Carsten Melissa K , Uhl-Bien Mary , Huang Lei
Published: July 2017

Followership research posits that followers differ in the way they define and enact the followership role, which can have varying effects in relation to how leaders experience their own roles and responsibilities. Drawing from the role orientation literature and newly emerging research on followership, our study examines the indirect effects of followers’ co-production (co-producing leadership outcomes) and passive (deferring to leadership influence) role orientations on leader-rated outcomes of perceived follower support, leader motivation, and follower contribution to goal attainment via followers’ voice and upward delegation behaviors. Using data from 306 dyads in a Chinese organization, our results show that follower voice and upward delegation mediate the relationships linking followers’ co-production and passive role orientations with leader-rated outcomes. Our study provides evidence that followership role orientations and behaviors differentially influence leader perceptions regarding their followers’ support, contribution to goal attainment, and leader motivation. Implications are drawn for further research on followership and the importance of considering leader outcomes as critical variables in leadership and followership literatures.
Testimony of terrorism: Civic responsibility and memory work after a political massacre
Authors: Zamperini Adriano , Passarella Letizia
Published: July 2017

Despite the wide use of testimonies in collective memory of violent historical and political events, proper psychosocial studies addressing the process of becoming a testimony remain scarce. In the context of the massacre of Piazza della Loggia in Brescia, this study examines the biographical transition from victims to testimonies of people directly or indirectly involved in the event. Through the use of semi-structured interviews, 13 biographical stories were collected and analysed through qualitative methodology. Out of the four biographical transitions evinced by the results of this study and besides the scenario of a victim not becoming a testimony, the results highlight three different biographical transitions: the immediate transition from victim to testimony, transition as awareness, and transition as a process of knowledge. These three biographical transitions are summarized in three types of identity: ‘heroic testimony’, ‘civic testimony’ and ‘epistemic testimony’. The results are hence discussed in the light of the community practices of collective memory and psychosocial research on the testimonies.
The settler-colonial imagination: Comparing commemoration in Saskatchewan and in Québec
Authors: Caldwell Lynn , Leroux Darryl
Published: July 2017

The authors present a comparative analysis of the Saskatchewan Centennial celebrations (2005) and the Québec quatercentenary celebrations (2008) informed by critical race theory, cultural studies, and studies of commemoration as overarching frameworks of analysis. This collaborative work considers two sites rarely analyzed together and examines how these major commemorative events narrate and represent relations among settlers and Indigenous peoples in Saskatchewan and in Québec. The analysis focuses on two significant events in each commemorative celebration: the Centennial Gala in Saskatchewan and Rencontres [Encounters] in Québec. While the contexts and narratives differ in significant ways, the two commemorations reveal their mutual investments in a national settler project. The authors contend that examining how Canada as a nation is remembered and currently imagined through such disparate sites and local histories provides critical insight into ongoing contentions about its constitution as a White settler society.
Difficult decisions: Choosing a practice
Authors: Harrison Kathryn
Published: July 2017

With the Clinical Skills Assessment successfully completed, focus shifts to the completion of training and starting work as an independent GP; it is both an exciting and unnerving time. The myriad of opportunities open to newly qualified GPs is one of the specialty’s strengths, offering scope for personal and professional development. Opportunities can be diverse and include working overseas, teaching, developing a special interest, pursuing academic research, media roles, working with the RCGP, and many more. Most of these roles can be undertaken alongside clinical practice as part of a portfolio career, each complementing and enhancing the other. Whether pursuing wider opportunities, or gaining more experience in clinical practice, choosing the right practice with like-minded colleagues in the early stages of your career can be a difficult, daunting prospect. This article aims to offer guidance for those searching for the right practice.
“We have seen paradoxa today”—What Have We Seen? Brief Thoughts on the Translation of paradoxos in Luke 5.26
Authors: Locker Markus
Published: July 2017

This paper assumes that Luke, by using the term paradoxa in Luke 5.26, intends to convey a significance to the words and deeds of Jesus in Luke 5.17-26 that could not have been captured equally well by standard Greek expressions, such as “extraordinary” or “strange.” A study of Luke’s placement of 5.17-26 in his narrative and a brief survey of the meaning of paradox in antiquity allows for the assumption that paradoxa could mean different things for the various audiences of this scene: “glorious” things for the believer and “inglorious” things for the unbeliever.
Rethinking the Translation of Διδακτικός in 1 Timothy 3.2 and 2 Timothy 2.24
Authors: Himes Paul A.
Published: July 2017

Biblical scholars and translations since John Calvin have generally understood διδακτικός in 1 Tim 3.2 and 2 Tim 2.24 as “skillful in teaching,” with a minority holding to “teachable.” Yet neither view has adequately taken into account either the linguistic evidence or contextual considerations. This article contends that, based on semantic and contextual data, διδακτικός should be translated “characterized by teaching,” that is, focusing on the fact that the would-be overseer and the “servant of the Lord” should both already have experience teaching.

Published: July 2017

Introduction

The objective of this study is to compare the clinical profile, risk factors, type and outcome of stroke patients in urban and rural areas of Punjab, India.

Methods

The primary data source was from the Ludhiana urban population-based stroke registry. The data of first-ever stroke patients with age ≥18 years were collected using WHO stepwise approach from all hospitals, general practitioners, physiotherapy and scan centres between 26 March 2011 and 25 March 2013.

Results

A total of 4989 patients were included and out of 4989 patients, 3469 (69%) were from urban areas. Haemorrhagic stroke was seen more in rural as compared to urban regions (urban 1104 (32%) versus rural 552 (36%); p = 0.01). There were significant differences seen in stroke risk factors; hypertension (urban 1923 (84%) versus rural 926 (89%); p = 0.001) and hyperlipidaemia (urban 397 (18%) versus rural 234 (23%); p = 0.001) between two groups. In the multivariable analysis the rural patients were more likely to be younger (age < 40 years) (OR: 1.82; 95% CI: 1.24–2.68; p = 0.002), Sikhs (OR: 2.57; 95% CI: 1.26–5.22; p = 0.009), farmers (OR: 9.41; 95% CI: 5.36–16.50; p < 0.001), housewives (OR: 2.71; 95% CI: 1.45–5.06; p = 0.002), and consumed alcohol (OR: 1.57; 95% CI: 1.19–2.06; p = 0.001) as compared to urban patients. In addition, use of imaging was higher in rural patients (OR: 1.99; 95% CI: 1.06–3.74; p = 0.03) as compared to urban patients.

Discussion and Conclusion

In this large cohort of patients, rural and urban differences were seen in risk factors and type of stroke. Stroke prevention strategies need to take into consideration these factors including regional sociocultural practices.
How I treat myeloma with new agents
Authors: Moreau Philippe
Published: July 2017

At present, multiple classes of agents with distinct mechanisms of action are available for the treatment of patients with multiple myeloma (MM), including alkylators, steroids, immunomodulatory agents (IMiDs), proteasome inhibitors (PIs), histone deacetylase inhibitors (DACIs), and monoclonal antibodies (mAbs). Over the last 5 years, several new agents, such as the third-generation IMiD pomalidomide, the second-generation PIs carfilzomib and ixazomib, the DACI panobinostat, and 2 mAbs, elotuzumab and daratumumab, have been approved, incorporated into clinical guidelines, and have transformed our approach to the treatment of patients. These agents may be part of doublet or triplet combinations, or incorporated into intensive strategies with autologous stem cell transplantation. In this review, I discuss the different treatment options available today for the treatment of MM in frontline and relapse settings.
Handpad: a virtual mouse for controlling laptops in a smart home
Authors: Taing Clerc-Manne , Rau Pei-Luen Patrick , Huang Hanjing
Published: July 2017

This study investigates the possibilities of equipping fixed furniture with touch screens to control laptops or other smart home devices, to create a holistic smart home control system. Although multi-touch screens have recently been integrated into desktop use, most users prefer a classical mouse for desktop input. This study introduces Handpad, which is a new indirect touch input device designed to control laptops in a smart home. Handpad combines the mobility of a touch screen with the precision of a mouse by tracking whole-hand movement on the touch screen and moving the screen pointer accordingly. In a user test, participants showed a high level of acceptance and positive attitudes toward Handpad.

Published: July 2017

Mentors rarely receive education about the unique needs of underrepresented scholars in the biomedical and behavioral sciences. We hypothesized that mentor-training and peer-mentoring interventions for these scholars would enrich the perceived quality and breadth of discussions between mentor–protégé dyads (i.e., mentor–protégé pairs). Our multicenter, randomized study of 150 underrepresented scholar–mentor dyads compared: 1) mentor training, 2) protégé peer mentoring, 3) combined mentor training and peer mentoring, and 4) a control condition (i.e., usual practice of mentoring). In this secondary analysis, the outcome variables were quality of dyad time and breadth of their discussions. Protégé participants were graduate students, fellows, and junior faculty in behavioral and biomedical research and healthcare. Dyads with mentor training were more likely than those without mentor training to have discussed teaching and work–life balance. Dyads with peer mentoring were more likely than those without peer mentoring to have discussed clinical care and career plans. The combined intervention dyads were more likely than controls to perceive that the quality of their time together was good/excellent. Our study supports the value of these mentoring interventions to enhance the breadth of dyad discussions and quality of time together, both important components of a good mentoring relationship.
Frontline Science: A hyporesponsive subset of rat NK cells negative for Ly49s3 and NKR-P1B are precursors to the functionally mature NKR-P1B+ subset
Authors: Sudworth Amanda , Vaage John T , Inngjerdingen Marit , Kveberg Lise
Published: July 2017

Rat NK cells are divided into major subsets expressing either Ly49 receptors or the inhibitory NKR-P1B receptor in conjunction with NKG2A/C/E receptors. A minor subset of NKp46+ cells lacking expression of both Ly49 receptors and NKR-P1B is present in blood and spleen and is associated with decreased functional competence. We hypothesized that this subset may represent precursors to Ly49+ and/or NKR-P1B+ NK cells. When cultured in vitro in IL-2 and IL-15 or adoptively transferred to syngeneic hosts, a portion of NKR-P1B−Ly49s3− cells transformed to express NKR-P1B, but very little Ly49s3. Acquisition of NKR-P1B by NKR-P1B−Ly49s3− cells coincided with increased degranulation. In addition, although NKR-P1B−Ly49s3− cells highly proliferate, proliferative activity was reduced upon acquisition of NKR-P1B at comparable levels to bona fide NKR-P1B+ NK cells. A fraction of NKR-P1B−Ly49s3− cells remained negative for NKR-P1B, both in vitro and after adoptive transfer in vivo. Most NKR-P1B−Ly49s3− cells expressed the transcription factor Eomesodermin and NK cell markers, indicating that these cells represent conventional NK cells. Our findings suggest that the NKR-P1B−Ly49s3− NK cells are precursors to NKR-P1B single-positive cells and that functional competence is acquired upon expression of NKR-P1B.
Simultaneous Search and Efficiency of Entry and Search Intensity
Authors: Gautier Pieter A. , Holzner Christian L.
Published: July 2017

We consider a model where firms open vacancies and post and commit to a wage mechanism. Search is costly and workers simultaneously apply to multiple jobs. Firms can be connected to multiple workers and workers to multiple firms. We use a new method to derive the expected maximum number of matches in a large market as a function of the number of applications and market tightness. We also derive the conditions under which firm entry, worker participation, and search intensity are socially efficient. Finally, we show that a sequential auction under incomplete information can establish the social optimum and discuss some alternative mechanisms that can, under complete information of the entire network, also deliver social efficiency.

Impact of robotic ultrasound image guidance on plan quality in SBRT of the prostate
Authors: Gerlach Stefan , Kuhlemann Ivo , Ernst Floris , Fürweger Christoph , Schlaefer Alexander
Published: July 2017

Objective:

Ultrasound provides good image quality, fast volumetric imaging and is established for abdominal image guidance. Robotic transducer placement may facilitate intrafractional motion compensation in radiation therapy. We consider integration with the CyberKnife and study whether the kinematic redundancy of a seven-degrees-of-freedom robot allows for acceptable plan quality for prostate treatments.

Methods:

Reference treatment plans were generated for 10 prostate cancer cases previously treated with the CyberKnife. Considering transducer and prostate motion by different safety margins, 10 different robot poses, and 3 different elbow configurations, we removed all beams colliding with robot or transducer. For each combination, plans were generated using the same strict dose constraints and the objective to maximize the target coverage. Additionally, plans for the union of all unblocked beams were generated.

Results:

In 9 cases the planning target coverage with the ultrasound robot was within 1.1 percentage points of the reference coverage. It was 1.7 percentage points for one large prostate. For one preferable robot position, kinematic redundancy decreased the average number of blocked beam directions from 23.1 to 14.5.

Conclusion:

The impact of beam blocking can largely be offset by treatment planning and using a kinematically redundant robot. Plan quality can be maintained by carefully choosing the ultrasound robot position and pose. For smaller planning target volumes the difference in coverage is negligible for safety margins of up to 35 mm.

Advances in knowledge:

Integrating a robot for online intrafractional image guidance based on ultrasound can be realized while maintaining acceptable plan quality for prostate cancer treatments with the CyberKnife.
Direct shoulder magnetic resonance arthrography for superior labral anterior-to-posterior (SLAP) and Bankart lesions: investigation into the appropriate dose and level of local anesthesia
Authors: Lee Sun Hwa , Yun Seong Jong , Jo Hyeon Hwan , Kim Dong Hyeon , Song Jae Gwang , Park Yong Sung
Published: July 2017

Objective:

To compare contrast leakage, pain score, image quality and diagnostic performance at different doses and levels of local anaesthesia for direct shoulder magnetic resonance arthrography.

Methods:

Patients (n = 157) were prospectively enrolled and allocated to Group 1 (no local anaesthetic), Group 2 (local anaesthesia to subcutaneous fat level; lidocaine 1–2 ml), Group 3 (to deltoid muscle level; 3–5 ml), or Group 4 (to subscapularis muscle level; 6–8 ml). We evaluated the frequency of contrast leakage, periprocedural/postprocedural pain, contrast-to-noise ratio of the intra-articular signal, and subjective image noise/image sharpness. Radiological diagnoses of superior anterior-to-posterior (SLAP) and Bankart lesions were assessed. All data were analysed by one-way analysis of variance/Kruskal–Wall, Χ  2/Fisher's exact and DeLong’s tests.

Results:

The frequency of contrast leakage from the injection path and subjective image noise were significantly lower in Groups 1 and 2 than in Groups 3 and 4 (p = 0.001–0.04). Periprocedural/postprocedural pain scores among Groups 2–4 were similar and lower than those of Group 1. The contrast-to-noise ratio (p = 0.11–0.97) and image sharpness (p = 0.12–0.43) were similar among Groups 2–4 and significantly lower than those of Group 1 (p = 0.001–0.02). The diagnostic performance for the assessment of superior anterior-to-posterior and Bankart lesions was better in Groups 2–4 than in Group 1, although there were no significant differences (p = 0.23–0.99).

Conclusion:

Local anaesthesia with 1–2 ml lidocaine at subcutaneous fat level reduced pain and provided optimal image quality in direct shoulder magnetic resonance arthrography.

Advances in knowledge:

This method can increase image quality, reduce periprocedural/postprocedural pain and potentially reduce the need for re-examination.
THE EMPLACEMENT OF THE VERMION NAPPE IN THE AREA OF KATO SELI (MT VERMION, CENTRAL MACEDONIA, GREECE)
Authors: Georgiadis G.A. , Tranos M.D. , Kilias A.A. , Mountrakis D.M.
Published: July 2017

Our fieldwork in the area of Kato Seli of Mt Vermion suggests that the Vermion Nappe is not only tectonically overlying the Maastrichtian flysch of the Pelagonian Zone, but also a Jurassic melange that overlies the Triassic-Jurassic marbles of the Pelagonian Zone. Moreover, between the Vermion Nappe and the underlying melange, tectonic slivers of meta-sandstones-meta-rudites are tectonically emplaced. This calls for a reassessment of the emplacement of the Vermion Nappe and its role in the geotectonic evolution of the area.
NEOGENE AND QUATERNARY CONTINENTAL BIOSTRATIGRAPHY OF GREECE BASED ON MAMMALS
Authors: Koufos G.D.
Published: July 2017

Most basins of Greece were filled with thick Neogene-Quaternary continental deposits, which include a large number of mammal fossiliferous sites. The investigations of the last 40 years in the various basins of Greece led to the discovery of many new fossiliferous sites. The extensive, long time and continuous excavations in the new fossiliferous sites as well as in the previously known ones - like the classical localities of Axios Valley, Pikermi and Samos Island - provided numerous fossils enriching remarkably the Greek fossil mammal record. The systematic study of these collections provided numerous data for their biochronology. Further magnetostratigraphic, radiometric or other methods of absolute chronology provided additional chronological data for the mammal faunas and the corresponding deposits. The correlation of all these data allowed the biostratigraphic classification of the continental Neogene Quaternary deposits of Greece which is given in the biostratigraphic tables of the present article. From these tables it is clear that for some time-intervals (Late Miocene, Early Pleistocene) the data are abundant allowing a detailed biostratigraphy, but for some others (Early- Middle Miocene, Pliocene, and for some time-spans of Early Pleistocene) the data are  imited or missing and cannot allow an accurate and complete biostratigraphy.
THE MISSING SOFT LINK? EVIDENCE FOR MARGINAL FAULT INTERACTION AT THE SOUTHERN MARGIN OF GERANEIA MOUNTAINS, CENTRAL GREECE
Authors: Kranis H.
Published: July 2017

We examine the structure of the southern faulted margin of Geraneia Mountains, controlled by two marginal faults, namely the Loutraki and Kakia Skala Faults, which have been active in the Quaternary; however, Holocene activity on these structures has not been verified. Structural observations at the probable overlap zone between these two faults, suggest that they became soft-linked, or linkage ended at its early stage, before activity migrated basinwards, with consequent footwall backtilt. The affinity of the kinematics in the accommodation zone with the present-day extensional stress field might hint at possible Late Quaternary activity on these two major faults.
THE CALLOVIAN UNCONFORMITY AND THE OPHIOLITE OBDUCTION ONTO THE PELAGONIAN CARBONATE PLATFORM OF THE INTERNAL HELLENIDES
Authors: Scherreiks R. , Meléndez G. , Bouldagher-Fadel M. , Fermeli G. , Bosence D.
Published: July 2017

The carbonate-platform-complex and the oceanic formations of the central Pelagonian zone of the Hellenides evolved in response to a sequence of plate tectonic episodes of ocean spreading, plate convergence and ophiolite obduction. The biostratigraphies of the carbonate platform and the oceanic successions, show that the Triassic-Early Jurassic platform was coeval with an ocean where pillow basalts and radiolarian cherts were being deposited. After convergence began during late Early- Jurassic - Middle Jurassic time, the oceanic leading edge of the Pelagonian plate was subducted beneath the leading edge of the oceanic, overriding plate. The platform subsided while a supra-subduction, volcanic-island-arc evolved. Biostratigraphic and geochemical evidence shows that the platform and the oceanic floor, temporarily became subaerially exposed during Callovian time. This “Callovian event” is suggested to have taken place as oceanic lithosphere first made compressional, tectonic contact with the carbonate platform, initiating a basal detachment fault, along which the platform was thrust upwards. The central Pelagonian zone became an extensive land area that was supplied with laterite from an ophiolite highland. A similar emergence of Vardar ophiolite most likely took place in the Guevgueli area. The Callovian emergence shows that the initial ophiolite obduction onto the platform took place about 25 million years before the final emplacement of the ophiolite during Valanginian time.
ALPINE BASEMENT OUTCROPS AT NORTHERN PELOPONNESUS: IMPLICATIONS FOR THE EARLY STAGES IN THE EVOLUTION OF THE CORINTH RIFT
Authors: Skourtsos E. , Kranis H. , Zambetakis-Lekkas A. , Gawthorpe R. , Leeder M.
Published: July 2017

We focus on the central and eastern southern onshore parts of the Corinth Rift (CR), where basement outcrops are few and of limited extent, to study three key locations: a basement inlier east of Xylokastro, a new outcrop of the Tripolis Unit at the western edge of the Xylokastro horst, and a re-mapped and re-evaluated outcrop of the Pindos Unit northwest of Nemea. The results of this study show that there are elements which could help overcome the significant difficulties in our understanding of the structure and evolution of the rift, posed by the lack of basement outcrops in the central and eastern onshore parts of the Rift. This, in turn, calls for a reconsideration of the generally accepted idea that the broader onshore eastern sector of the CR lacks significant basement and intrabasinal faults.
SEDIMENTOLOGICAL AND GEOCHEMICAL ANALYSIS OF MIOCENE DEPOSITS IN MOSCHOPOTAMOS AREA, IN THE WESTERN PART OF AXIOS-THERMAIKOS BASIN, NW GREECE
Authors: Savva V. , Tserolas P. , Maravelis A. , Bourli N. , Zelilidis A.
Published: July 2017

A total of 27 samples of the Moschopotamos area lignite-bearing strata were studied in regard of their geochemical and sedimentary characteristics. Organic content and calcium carbonate evaluation, sieve analysis and micropaleontological observations were used and combined to investigate the paleoenvironment and the depositional conditions of the study area. TOC analysis showed that organic matter values range from 0.07% up to 13.42% with an average of ~3.26 %. The high average of organic carbon content indicates a promising basis for the sediments’ source rock potential, inquiring further and thorough examination. CaCO3 measurements present a range between 4% and 23%. A comparison between TOC-CaCO3 content throughout the stratigraphic column presented certain synchronous and inverse trends, due to alterations of the depositional conditions. This study provides new insights for the understanding of the broader Axios-Thermaikos basin, and depositional conditions in the North Aegean area.
GEOMORPHOLOGICAL AND PALEOENVIRONMENTAL CHANGES OF ISMARIDA LAKE DURING HOLOCENE (N. GREECE)
Authors: Karadimou G. , Vouvalidis K. , Syrides G. , Koukousioura O. , Aidona E.
Published: July 2017

In this research, the geomorphological and environmental changes of Lake Ismarida during Holocene are studied. Ismarida is located 20Km south of Komotini city and 5Km NNE of the archeological site of ancient Stryme at Rhodope Province, (N. Greece). The analysis of geomorphological, paleontological, sedimentological and magnetic susceptibility data as well as the evaluation of 14C datings, showed that four environmental units are recognized in the lake sediments. The environment changed from shallow marine to open lagoonal of low energy (~5400-3400 years BP), to shallow marine to open lagoonal of high energy (~3400-3000 years BP), subsequently turned into brackish to lagoonal with fresh water inputs (~3000-2000 years BP), and finally formed to fluvial-terrestrial, until present time. The Lake Ismarida as it is known today was formed 2000 years BP on the isolated western part of th pre-Holocene valley between the deltaic deposits of the rivers Filiouris and Vosvozis.

Prominent geomorphological features of the shallow continental shelf west of the Kavala Bay (Loutra Eleftheron-Nea Peramos) were mapped using the data from a hydrographic survey (June 2014) of 320 nautical miles during which high resolution multibeam bathymetry and seismic-reflection subbottom profiling were carried out simultaneously. A fault zone comprised by a set of two primary sigmoidal gravity faults (recorded lengths and measured offsets: 12 km, 5 km and > 40 m, 25 m, respectively), with distinct expression on the seabed, and three other secondary gravity faults situated southern of the major faults, revealing synsedimentary tectonics, was identified. The striking difference between the texture of the footwall block sediments of the northern major fault and the texture of the sediments occupying the deep hanging wall block of the southern major fault emphasizes the impact of local tectonics on the sedimentary evolution of the study area. Concerning the observed bedforms, the most interesting were the sand dunes occurring at depths from 25 m to 65 m at least and occupying the northeast part of the study area. Their large dimensions and orientation in relation to the coastline position imply as a mechanism for their formation intense bottom-current activity.

The joint application of benthic foraminifera, pollen and non-pollen palynomorphs (NPPs), molluscs and magnetic susceptibility analyses in Piraeus coastal plain deposits resulted in the detailed study of palaeoenvironmental evolution of the area during almost the last 9000 years and the distinction of five lithostratigraphicalpaleoenvironmental units and subunits. Combined results of our analyses features the occurrence of an inner lagoon (unit Aa) followed by  open lagoon (Unit Ab) depositional environment that was transformed to a shallow marine paleoenvironment with lagoonal features (Unit B) after 7800 BP. Since about 4800 BP a closed oligohaline lagoon (Unit C) used for grazing, occurred in the area, while after 2800 BP a marshy oligohaline depositional environment (Unit D) and signs of intensive agricultural activities are evidenced. The very good correlation of benthic foraminiferal, palynological, molluscan and magnetic susceptibility data and resulted indices is indicative of the potential of the applied methodologies as a paleoenvironmental tool box.

Published: July 2017

A paleoseismological analysis has been performed at the East Giouchtas Fault. This fault dips to the east and represents a pure normal fault. The East Giouchtas Fault forms an intrabasinal high in the Heraklion basin with its conjugate fault the West Giouchtas Fault. A natural surface has been prepared and logged in detail in order to detect the most significant parameters related to the ground shaking impact on the area. Investigating past earthquakes characteristics attributed to the East Giouchtas Fault and through sample dating we conclude that the studied fault is related to at least four strong events of 6.4 magnitude. The fault is also characterized by 20-40 cm tectonosedimentatry displacements and slip rates of 0.25 mm/yr. Thus, the proximity of the fault to the highly populated Heraklion city and Minoan Knossos monument urges the need for an adequate hazard assessment of the area.

Published: July 2017

The area of Alexandria is located in the Thessaloniki basin that has been filled with more than 4 km of sediments. In 1980, oil exploration borehole AL-1, 1,705 m deep, was drilled north of the town of Alexandria and the temperatures of 39 and 65oC were recorded at depths of 700 and 1,705 m respectively. During 1996-2000, two geothermal exploration boreholes were drilled at depths of 532 and 620 m penetrating Quaternary and Pliocene sediments and the temperatures of 30.1 and 33.4oC were measured at 500 and 611 m respectively. The preliminary geothermal investigation resulted in the construction of the first production well (GN-1P). It was drilled to a depth of 805 m penetrating clays, sands, tuffs, marls, clayey marls, marly limestones, gravels, sandstones and conglomerates. The borehole was cased down to 805 m and screens were placed at various depths below 607 m. Temperature and electrical conductivity values of 35.1-37.2oC and 5,100-8,200 μS/cm respectively were recorded at depths of 607-800 m. This well discharges 30-40 m3/h waters at 34.1oC with artesian flow and provides 130 m3/h waters at 35.5oC with pumping. The produced geothermal water with TDS of 2.18 g/l belongs to the Na-Cl type differentiated from the shallow waters. The thermal capacity of well GN-1P is calculated to be 1.65 MWt.
THE USE OF THE DRASTIC METHOD AND GIS IN ASSEESSING THE VULNERABILITY OF THE GROUNDWATER, IN THE VELIPOJA -ZADRIMA AQUIFER, ALBANIA
Authors: Bele S.
Published: July 2017

The Albanian plain area is densely populated. The population doubled during the last two decades and most of it uses the groundwaters of these aquifers. Aquifers in lowland areas are vulnerable to pollution. This article assesses the vulnerability of groundwater Velipoj-Zadrimè aquifer. This aquifer has a surface of 237 km2 and an average height of 10m above sea level. Groundwater recourses are connected with alluvial deposits formed by Drini and Buna rivers. The vulnerability Map is an ιmportant tool for the management of the territory. It guides the selection of areas for development projects, in order to avoid negative consequences on the quality of groundwater. Geographic Information Systems are very valuable programme for processing. The DRASTIC method has been used to map the natural aquifer vulnerability of the Velipoja-Zadrima study area. This method, applied to assess the vulnerability of the aquifer, was developed by the "Environmental Protection Agency (US EPA)" and "The National Association of Water Wells (NWWA)". It is a technique to assess the potential contamination of groundwater and is based on seven (7) parameters: Depth (D), Recharge (R), Aquifer media (A), Soil media (S), Topography (T), Impact of vadose zone (I), and Conductivity of the aquifer (C). The DRASTIC index is determined by the sum of the products of the Weight and site ratings of all the parameters. High values of vulnerability cover large areas of the aquifer. The results provide important information for local authorities in the management of resources and territory.
ASSESSMENT OF WATER LOSSES FROM BADOVC LAKE, KOSOVO: ISOTOPIC IMPLICATIONS
Authors: Skender B. , Arjan B.
Published: July 2017

This paper aims to quantitatively assess water losses of Badovc Lake - Kosovo based on both water balance of the lake and water isotopic composition of H-2 and O-18. According to lake water balance, a water loss of 3,738,905 m³ for the hydrologic year 2014, was evaluated. These consistent data favour the opinion that a continuous groundwater outflow from the lake is present and it is conditioned by the intensively developed fracture system in the lake basement formations. This was also supported by the isotopic analysis (H-2 and O-18) of the sampled waters. Most of water samples taken from hydrologic components of Lake Badovc fall on a linear plot of δ2H versus δ18O showing an isotopic variation typical for waters evaporated from a lake and fits very well with Global Meteoric Water Line (GMWL), while two rain water samples are isotopically lighter (more negative δ values). Water samples taken from water leakages on the right side of the dam, the piezometer, two wells drilled in the valley downstream of dam, Hajvalia mine gallery and the water flow downstream of the dam, have isotopic composition similar with that of the lake water. Water of Hajvalia mine well shows isotopic composition that falls between that of rain water and lake water. Considering δ values of rain water (δ2H= -129.6‰, δ18O= -16.56‰) and lake water (δ2H= -67.2‰, δ18O= -9.20‰) and mine water (mixture) (δ2H= -73.3‰, δ18O= -10.15‰) was found that the fraction of rain water in mine water ranges from 6% (according H-2) to 10% (according O-18), while the fraction of lake water in minewater varies from 94% (according H-2) to 90% (according O-18).
HYDROCHEMICAL CHARACTERISTICS AND GEOTHERMOMETRY APPLICATIONS OF HOT GROUNDWATER IN EDIPSOS AREA, NW EUBOEA (EVIA), GREECE

Published: July 2017

In Edipsos area many hot springs occur, as a result of both active tectonic of the area and recent volcanism (Lichades volcanic center). A geochemical study of Edipsos hot groundwaters was undertaken, in order to assess the hydrochemistry of hot springs from Edipsos and re-evaluate the geothermal situation of the area. For that purpose, 12 water samples were collected and analyzed by Spectrophotometry for the main ions and by AAS, ICP-OES and ICP-MS for major and trace elements. The interpretation of the analytical data showed that the geochemistry of Edipsos hot groundwaters is controlled by three factors i) a deep magmatic source, ii) the chemical composition of the local rocks (ultramafic and carbonates) and iii) sea water. The application of chemical geothermometers is problematic because of the chemical composition of the hot groundwaters and especially the high participation of the sea water. The temperature which derives from the use of Na-K-Ca geothermometer is greater than 160°C. Although, several studies have conducted in the area still remain unanswered questions concerning the underground circulation of the hot groundwater, in which only deep drilling data could give answers.
GIS: A USEFUL TOOL FOR MANAGING OF TRANSBOUNDARY AQUIFERS: A CASE STUDY FROM PRESPA LAKE BASIN
Authors: Kiri E.
Published: July 2017

Prespa Lake Basin is a transboundary basin that’s shared between Albania-Greece-FYROM. This region has a very complicated geology. The main aquifer systems are developed in carbonate rocks (karst aquifers) crossing international borders (transboundary aquifers). A map was constructed in GIS environment clearly display that each geologic age has one index, in one polygon, with the respective geological formation. The map was first digitalized with an AutoCAD program and then all the layers were exported in the program mentioned above. Not only does this map represent the hydrogeological features of the area but it also serves as a database of general characteristics, such as, the rock type, the infiltration coefficient, the yield of wells and springs, groundwater resource and permeability can be found on this base. Furthermore, chemical data can be added to the map, supplying more information on the surface and groundwater. Geographical Information Systems (GIS) is a useful tool for water resources management in the frame of international cooperation and coordination.
ENGINEERING GEOLOGICAL CONDITIONS OF THESSALONIKI BASIN FOR UNDERGROUND WORKS
Authors: Kokkala A. , Marinos V.
Published: July 2017

The design and construction of underground works in an urban environment, face several geological challenges. The construction of a well-structured database, able to store, manage, analyse and correlate a large amount of geological and geotechnical data, is a powerful tool towards the geological hazard assessment and the geotechnical characterisation of the formations along a tunnel. The data processed by the database are based on borehole geological information, laboratory testing, geotechnical characterisation and in situ field tests, mainly executed in the quaternary and neogene soil formations that are met along the studied area. The processing and assessment of the information, leads to the identification of useful value ranges for several physical and mechanical parameters. The study also focuses in specific areas within the basin of Thessaloniki, highlighting the in situ conditions, by the construction of longitudinal profiles. The purpose of that process, besides incorporating new data, is to provide a tool for turning data into useful information in order to estimate the geological situation and geotechnical behavior of formations in underground works.
SEASONAL STOCHASTIC SIMULATION AND TIMESERIES MODELLING - ANALYSIS OF A KARSTIC SPRING IN CENTRAL MACEDONIA, GREECE
Authors: Lappas I. , Lazaridou M.
Published: July 2017

The objective of this paper is to find an appropriate Seasonal Auto-Regressive Integrated Moving Average (SARIMA) model for fitting the monthly discharge of a karstic spring located at the North of the city of Serres (Agios Ioannis, Mount Menikio) by considering the minimum of Akaike Information Criterion (AIC). Box- Jenkins methodology applies models to find the best fit of a timeseries to past values of this timeseries, in order to make forecasting and consists of a four-step iterative procedure: identification, estimation, diagnostic check and forecasting. Timeseries analysis and forecasting of hydrological parameters such as spring discharge may be useful in decision making and optimum water resources usage. In this study, monthly discharge measurements are analysed. Initial data are firstly transformed to normal and stationary using differencing methods. Autocorrelation and Partial Autocorrelation functions are calculated to determine the order of Autoregressive and Moving Average parameters and residuals are then checked to show the “white noise”. The spring discharge data are forecasted based on the selected model up to 2008 and are then compared with measured values. The timeseries model SARIMA (2,1,1)(1,0,1)12 could be used in monthly discharge forecasting at a short time (upcoming one year) with a simple and explicit model structure in order to help decision m akers to establish priorities in terms of water demand management. Finally, the corr elation coefficient between the observed and fitted data is essentially high, while the absolute and relative errors are significantly low.
