Published: July 2018

Background

Frailty is increasing in prevalence and poses a formidable challenge for clinicians. The cardiac surgery literature consists primarily of small single‐center studies with limited follow‐up, and the epidemiological features of frailty remain to be elucidated in long‐term follow‐up.

Methods and Results

We conducted a population‐based, retrospective, cohort study in Ontario, Canada, between 2008 and 2015. Frailty was defined using the Johns Hopkins Adjusted Clinical Groups frailty indicator (a multidimensional instrument validated for research using administrative data). The primary outcome was mortality. Mortality rates were calculated using the Kaplan‐Meier method. The hazard of death was assessed using a multivariable Cox proportional hazard model. Of 40 083 patients, 8803 (22%) were frail. At 4±2 years of follow‐up, age‐ and sex‐standardized mortality rate per 1000 person‐years was higher in frail (33; 95% confidence interval, 29–36) compared with nonfrail (22; 95% confidence interval, 19–24) patients. Frailty was associated with an increased risk of long‐term mortality (adjusted hazard ratio, 1.20; 95% confidence interval, 1.12–1.28) and greater differences in the survival of patients between 40 and 74 years of age than in those who were ≥85 years old.

Conclusions

Frailty was present in a large proportion of patients undergoing coronary artery bypass grafting and was independently associated with long‐term mortality. The adjusted risk of frailty‐related death was inversely proportional to age. Our findings highlight the need for more comprehensive preoperative risk stratification models to assist with optimal selection of operative candidates. In addition, we identified the <75 years age group as a potential target for comprehensive preoperative optimization programs, such as cardiac prehabilitation, nutritional augmentation, and psychosocial support.
The Non-combatant Casualty Cut-off Value: Assessment of a Novel Targeting Technique in Operation Inherent Resolve
Authors: Graham Scott
Published: July 2018

A tension exists between treaty protections afforded to civilians in non-international armed conflicts from becoming objects of attacks and the International Criminal Court’s jurisdiction to punish commanders who recklessly cause such casualties. Yet, media and human rights organizations’ criticism that the non-combatant casualty cut-off value (NCV) constitutes a war crime cannot survive rational examination of the mens rea requirement in the Rome Statute. Coalition commanders and targeteers must ensure the NCV is neither presumptively nor conclusively applied in target engagement, whilst taking constant care to focus proportionality assessments to spare civilians.

Microlicia frankii is described, illustrated, and compared with M. ericoides and M. juniperina. It is distinguished by its reduced habit (3–15 cm in height), leaves linear-oblong 2–5 mm long, glandular-punctate on both surfaces, flowers apical and solitary, calyx lobes narrowly-triangular 3.5–7 mm long, petals magenta, isomorphic stamens, and tetrasporangiate thecae. The new species is probably endemic to Serra do Cipó, Minas Gerais, Brazil.
A historical review of the taxonomy and classification of Entocytheridae (Crustacea: Ostracoda: Podocopida)
Authors: WILLIAMS BRONWYN W. , WEAVER PATRICIA G.
Published: July 2018

Ostracods of the family Entocytheridae are obligate ectosymbionts of other crustaceans, including crayfishes, isopods, amphipods, and a species of freshwater crab. Entocytheridae, with five subfamilies, 35 genera, and 213 currently accepted species, represents one the most diverse groups of extant freshwater ostracods. Here, we present the results of an extensive literature review, documenting the often complex historical taxonomic activity and resulting classification of Entocytheridae. This overview highlights inconsistencies, errors, and additional sources of confusion that have been inadvertently introduced into the literature, a number of which have remained uncorrected for decades. Also provided is a comprehensive checklist of taxonomic nomenclature and a list of currently accepted names in Entocytheridae.
The concentration of total sialic acid in chronic hepatitis B and C
Authors: Gruszewska Ewa , Cylwik Bogdan , Gudowska Monika , Panasiuk Anatol , Flisiak Robert , Chrostek Lech
Published: July 2018

Background

The synthesis and glycosylation of glycoproteins and glycolipids take place in the liver. Thus, liver diseases may affect serum concentrations of some carbohydrate derivatives, especially the concentration of sialic acid which is attached to the end of oligosaccharide chains. The aim of this study was to measure and compare the serum concentration of total sialic acid in chronic hepatitis B and C. The hypothesis is that both viruses responsible for the development of inflammation work differently at the cellular level.

Methods

Serum samples were obtained from 90 patients suffering from liver diseases: 50 from chronic hepatitis B and 40 from chronic hepatitis C at the time of diagnosis. The total sialic acid concentration in the serum was measured according to the enzymatic method using a colorimetric procedure.

Results

The mean total sialic acid concentration in patients with chronic hepatitis B was significantly lower than the mean concentration in the healthy group, while in patients with chronic hepatitis C, it was significantly higher than that in healthy people and in patients suffering from chronic hepatitis B. There were no significant differences in total sialic acid concentrations in patients with chronic hepatitis B and C according to the grade of portal/periportal activity, the grade of lobular activity and the stage of fibrosis.

Conclusions

We conclude that chronic viral hepatitis affects the total serum concentration of sialic acid. Moreover, the concentration of total sialic acid may be a useful marker to differentiate between chronic hepatitis B and C but is not useful for evaluation of the progression of these diseases.
The Gift of Psychological Closeness: How Feasible Versus Desirable Gifts Reduce Psychological Distance to the Giver

Published: July 2018

Gift-giving is a common form of social exchange but little research has examined how different gift types affect the psychological distance between giver and recipient. We examined how two types of gifts influence recipients’ perceived psychological distance to the giver. Specifically, we compared desirable gifts focused on the quality of the gift with feasible gifts focused on the gift’s practicality or ease of use. We found that feasible (vs. desirable) gifts led recipients to feel psychologically closer to givers (Studies 1-4). Further clarifying the process by which receiving a desirable versus feasible gift affects perceived distance, when recipients were told that the giver focused on the gift’s practicality or ease of use (vs. the gift’s overall quality), while holding the specific features of the gifts constant, they felt closer to the gift-giver (Study 5). These results shed light on how different gifts can influence interpersonal relationships.

Objective

This study was performed to determine the healing effects of pentoxifylline on molecular responses and protection against severe ischemic damage in the small intestine.

Methods

Thirty-six Wistar albino rats were divided into six groups. The superior mesenteric artery was clamped for 120 minutes, and reperfusion was performed for 60 minutes. Saline (0.4 mL), pentoxifylline (1 mg/kg), and pentoxifylline (10 mg/kg) were intraperitoneally administered to the rats in the C1, P1, and P3 groups, respectively, 60 minutes before ischemia and to the rats in the C2, P2, and P4 groups, respectively, during reperfusion onset. Malondialdehyde, myeloperoxidase, tumor necrosis factor alpha, interleukin-1 beta, and interleukin-6 in serum and tissue were measured by enzyme-linked immunosorbent assay. Intestinal ischemic injury was histopathologically evaluated by the Chiu score and immunohistochemical staining.

Results

All serum and tissue molecular responses were significantly blunted in the pentoxifylline-treated groups compared with the controls. Significant improvement in ischemic damage was demonstrated in the pentoxifylline-treated groups by histological grading and immunohistochemical scoring.

Conclusions

The protective effects of pentoxifylline were confirmed by molecular responses and histopathological examination.

Published: July 2018

A 60-year-old female was diagnosed with progressive systemic sclerosis and interstitial lung disease of two months’ duration. The patient was treated for Raynaud phenomenon with aspirin, nifedipine, colchicine, and naproxen. Two weeks after treatment, she developed widespread erythematous patches with blistering eruptions on the face, torso, and extremities, and also had erosion on the oral mucosa. Skin biopsy for histopathology and direct immunofluorescent studies were suggestive of lupus erythematosus. To the best of our knowledge, this is the first case of toxic epidermal necrolysis-like acute cutaneous lupus erythematosus in a patient with progressive systemic sclerosis.
Buzz at workplaces in knowledge-intensive service production: Spatial settings of temporary spatial proximity
Authors: Growe Anna
Published: July 2018

The objective of this paper is to understand temporary spatial proximity beyond temporary clusters, and to analyse rationales for the use of various spatial settings for temporary spatial proximity in the work processes of knowledge-intensive services. To contrast different types of temporary spatial proximity two basic types, ‘Meet and Mingle’ and ‘Move and Manage’, are identified. On the basis of qualitative interviews in knowledge-intensive sectors in six German cities, the distinct use of three types of spatial settings (workplaces, transit places and retreat places) to create the targeted temporary spatial proximity type of ‘Move and Manage’ is analysed. The paper discusses how such settings contribute to creating a specific atmosphere to support the work processes of knowledge-intensive services.

Published: July 2018

Three Florida pumas ( Puma concolor coryi) that had spent time in captivity prior to being released in the wild were found exhibiting respiratory signs and reluctance to move. All 3 pumas died shortly after immobilization, despite supportive veterinary care. Significant autopsy findings included necrotizing interstitial pneumonia, with pulmonary edema and hyaline membranes, and suppurative myocarditis. Organisms morphologically consistent with Bartonella henselae were identified in intravascular histiocytes in the lung of one of the pumas on histopathology and confirmed via transmission electron microscopy. B. henselae was detected in fresh lung tissue and confirmed by PCR and sequence analysis (16S-23S spacer region, pap31, and rpoB genes) from one of the affected pumas. In all affected pumas, B. henselae was detected by PCR in formalin-fixed, paraffin-embedded lung tissue, and positively staining organisms were identified in sections of lung by immunohistochemistry for B. henselae. In situ hybridization detected B. henselae DNA in lung tissue from 2 of 3 affected pumas. Our case series suggests that B. henselae can be associated with a fatal disease syndrome in Florida pumas. The cause of susceptibility to fatal disease associated with B. henselae infection in these pumas remains unknown.
The Starling’s Tale: A Performative Ethnography Showing Deaf Children’s Schooling in the Republic of Ireland
Authors: Deegan James G. , O’Connell Noel P.
Published: July 2018

The ways in which we approach children and childhood as variables of social analysis has undergone profound change in the last quarter century in the Republic of Ireland. This performative ethnography inquires into the secret lore and language of deaf children’s lives in one residential school. Out of sight of the community of the other, children willfully embodied a transgressive, liberatory, and decolonizing sign language of their own. Medium and message come together in this performative ethnography through a clutch of theatrical devices associated with the “epic theater” of the German playwright and theater director, Bertolt Brecht, including loosely connected scenes, storyline turns, political placards, and addresses to audience. Techniques associated with “found poetry,” or the literary equivalent of collage, are combined with pentimenti or a painting within a painting to fuse image and word and bring forward a critical and political aesthetics of deaf children and deaf schooling and new media for encouraging alternative social imaginaries and possible actions.
A comparison of professional versus citizen journalistic roles: Views from visual journalists
Authors: Chung Deborah S , Kim Yung Soo , Nah Seungahn
Published: July 2018

Using a Web-based survey targeting visual professionals, this study examines their professional role conceptions along with their views on emerging visual citizen contributors’ roles. While participants’ ratings of the two groups’ roles were generally correlated within each group, no correlations resulted between the two groups with the exception of the civic roles. Further, visual professionals rated their roles as significantly more important for all five roles. When assessing views on citizen-contributed visuals, it was clear that participants evaluated them with a critical eye, expressing dislike toward citizens’ visual contributions and deeming them a threat to their livelihood.
Finite element analyses and design of post-tensioned anchorage zone in ultra-high-performance concrete beams
Authors: Kim Joung Rae , Kwak Hyo-Gyoung , Kim Byung-Suk , Kwon Yangsu , Bouhjiti El Mahdi
Published: July 2018

This article presents analyses and the design of a post-tensioned anchorage zone made of ultra-high-performance concretes with three-dimensional finite element analyses. The structural behavior was investigated through the failure modes and cracking patterns to show the anchorage zone resistance enhancement with an increase of the strength in concrete. Since the anchorage failure is usually initiated from the local zone in the case of ultra-high-performance concrete beams that have compressive strength of more than 80 MPa, the placement of reinforcements can effectively be used to enhance the strength and ductility for the local zone. However, ultra-high-performance concrete requires a smaller amount of reinforcement than normal-strength concrete. Parametric analyses are carried out to show the effect of the spiral reinforcement on the strength of the anchorage zone, and comparison with the design guidelines in NCHRP Report 356 is made. Finally, improved guidelines are suggested to cover the design of ultra-high-performance concrete.
Deep variational auto-encoders: A promising tool for dimensionality reduction and ball bearing elements fault diagnosis
Authors: San Martin Gabriel , López Droguett Enrique , Meruane Viviane , das Chagas Moura Márcio
Published: July 2018

One of the main challenges that the industry faces when dealing with massive data for failure diagnosis is high dimensionality of such data. This can be tackled by dimensionality reduction method such as principal components analysis, which usually results in an improved fault diagnosis. Other available techniques include auto-encoders and its variants denoising auto-encoders and sparse auto-encoders. Most recently, variational auto-encoders are one of the most promising techniques for unsupervised learning with successful applications in image processing and speech recognition. Differently from other auto-encoder methods, variational auto-encoders use variational inference to generate a latent representation of the data and impose a distribution over the latent variables and the data itself. In this article, we propose a fully unsupervised deep variational auto-encoder-based approach for dimensionality reduction in fault diagnosis and explore the variational auto-encoder capabilities for such a task. This is achieved by comparing the latent representations provided by variational auto-encoders to the ones from principal components analysis as well as when no reduction is performed in ball bearings’ fault classification using vibration signals. To tackle massive sensor data, we propose different architectures for the variational auto-encoder’s encoder and decoder that are based on deep neural networks and deep convolutional neural networks. Experiments are also carried out by varying the data preprocessing methods for generating spectrograms and hand-engineering features as well as the use of raw vibration data, the architecture of the neural networks fault classifiers operating on the latent representations from variational auto-encoder and principal components analysis, the degree of data dimension reduction, and the size of the available labeled data used for training the fault classifiers. The results show that variational auto-encoders are a competent and promising tool for dimensionality reduction for use in fault diagnosis and worth further exploring their capabilities beyond vibration signals of ball bearing elements.
Comparative study of tensile tests based on Hopkinson bar for recycled aggregate concrete

Published: July 2018

To comparatively study the tensile properties and fracture patterns of recycled aggregate concrete with various replacement percentages (i.e. 0%, 25%, 50%, 75%, and 100%) of recycled coarse aggregate, the dynamic direct tensile tests, splitting tests, and spalling tests of recycled aggregate concrete in the strain-rate range of 100–102 s−1 were carried out using large diameter (75 mm) split Hopkinson tensile bar and pressure bar. Test results show that for recycled aggregate concrete, the quasi-static direct tensile strength is more marvelous than its quasi-static splitting strength. When recycled coarse aggregate replacement percentage is 0%–75%, the replacement percentage impact minimally on the quasi-static tensile strength of recycled aggregate concrete. In dynamic tensile tests, there exists apparent difference between the dynamic direct tensile strength and dynamic splitting. The dynamic tensile strength of recycled aggregate concrete increases with the increase of average strain-rate in all three kinds of tests. The average strain-rate affects the damage form of recycled aggregate concrete, which indicates that the recycled aggregate concrete has obvious rate sensitivity. There shows no obvious regularity between the dynamic tensile strength and the recycled coarse aggregate replacement percentage. And the indirect tensile strength calculation method used in this article offers the theoretical basis for the engineering application of recycled aggregate concrete.
The fat embolism syndrome as a cause of paraplegia
Authors: Peters Siert TA , Witvliet Marieke J , Vennegoor Anke , ten Tusscher Birkitt , Boden Bauke , Bloemers Frank W
Published: July 2018

The fat embolism syndrome is a well-known complication in trauma patients. We describe a rare case of traumatic fat embolism that leads to paraplegia. A 19-year-old male motorcycle accident victim was presented to our hospital. After stabilization and trauma survey, he was diagnosed with bilateral femur fractures, a spleen laceration and a tear in the inferior vena cava, for which damage control surgery was performed. Post-operatively, the patient became paraplegic and developed a fluctuating consciousness, respiratory distress and petechiae. Fat embolism syndrome was considered as the most plausible cause of the paraplegia. The fat embolism syndrome is seen in approximately 1% of trauma patients, mostly those with bilateral fractures of the femur. Prevention of the syndrome depends on early stabilization of fractures. However, even with optimal care, this syndrome can still occur and may have dramatic consequences, as we demonstrate in this case.

Published: July 2018

Objective: To test the validity of a common measure of health-related quality of life (Short-Form-36 [SF-36]) in cognitively healthy older adults living in rural and urban Costa Rica. Method: Confirmatory factor analysis was applied to SF-36 data collected in 250 older adults from San Jose and Guanacaste, Costa Rica. Results: The best fitting model for the SF-36 was an eight first-order factor structure. A high correlation between the Mental Component Summary and Physical Component Summary scores was found. Region differences indicated that rural dwellers perceive a poorer health-related quality of life compared with the urban group. Discussion: Costa Rican older adults perceived health as a unidimensional construct. Age and urbanity of older adult Costa Ricans should be appreciated when trying to measure self-reported physical and mental health. Cultural context of the individuals should be considered when studying health-related quality of life.

Published: July 2018

Introduction:

Association of serotonin transporter gene ( 5-HTTLPR) polymorphisms with adverse cardiovascular (CV) events in women with suspected ischemia has not yet been reported. We hypothesized an association of 5-HTTLPR polymorphisms with risk of adverse CV events in women with suspected ischemic heart disease (IHD) referred for coronary angiography enrolled in the Women’s Ischemia Syndrome Evaluation (WISE).

Method:

We studied clinical and angiographic data and DNA from a cohort of 437 Caucasian women enrolled in the WISE genotyped for the long (L) and short (S) variant of the 5-HTTLPR polymorphism. Women were followed yearly for adverse CV events (defined as first occurrence of all-cause death, myocardial infarction, stroke, or heart failure hospitalization) with data collected at WISE 10-year follow-up. Exploratory analyses compared outcomes between genotype groups.

Results:

A total of 437 women, with baseline, angiographic, and long-term follow-up data, were successfully genotyped. Their mean age was 58 ± 11 years and body mass index 29 ± 6; 54% had hypertension, 18% diabetes, 50% dyslipidemia, 20% depression history, and only 34% had obstructive CAD. At 8.9 years median follow-up, the SS genotype was associated with significantly increased risk of adverse CV event versus LL + LS (1.93, confidence interval [CI]: 1.03-3.61, P = .03). Results were not significant for all-cause death (hazard ratio: 1.63, CI: 0.91-2.93, P = .09).

Conclusion:

Among a cohort of Caucasian women with suspected IHD enrolled in the WISE, the SS homozygous genotype for the 5-HTTLPR polymorphism was associated with increased risk of adverse CV outcomes.

Accurate recording of personality disorder in clinical practice
Authors: Tyrer Peter
Published: July 2018

Disturbances of personality are recorded very poorly in official statistics, but there are signs that this is changing. For many years, personality disorder has been either regarded as a secondary diagnosis that can be forgotten in the presence of another mental disorder, or avoided as the diagnosis gives the impression of untreatability or stigma. What is now abundantly clear is that under-diagnosis of personality disorder represents a disservice to patients and practitioners. It prevents a proper understanding of the longitudinal course of psychiatric disorder and an appreciation of some of the positive aspects of abnormal personality that can be used in treatment. We must no longer bury personality disorder, ostrich-like, in the diagnostic sand. It is there for the asking and needs to be embraced honestly and without fear if we are to improve the management of psychiatric patients.

Patient doses in endovascular and hybrid revascularization of the lower extremities
Authors: Kostova-Lefterova Desislava D , Nikolov Nadelin N , Stanev Stefan S , Stoyanova Boyka B
Published: July 2018

Objective:

Hybrid surgical methods such as remote endarterectomy and endovascular revascularization are fluoroscopy-guided procedures successfully replacing conventional open surgery for treatment of peripheral artery disease (PAD). The aim of this study was to: (1) evaluate the dose parameters describing exposure of patients undergoing endovascular or hybrid revascularization of the lower limb (below the inguinal ligament); (2) compare the data available in the literature with the evaluations of patients’ dose values and related factors for patients undergoing such procedures; (3) examine the correlation of doses with certain parameters; (4) estimate the peak skin dose and assess the potential for radiation-induced skin injuries during the procedures.

Methods:

Data for 259 patients were extracted retrospectively and analyzed. The procedures were grouped by type of intervention, vascular approach, and level of complexity. The analyses included the correlation of dose values with the operating team.

Results:

The air kerma-area product (KAP) and fluoroscopy time (FT) values greatly varied depending on the procedure type but also among patients undergoing the same procedure. The type of vascular access has the largest impact on patients’ doses. The KAP and FT values for brachial artery were: 347 Gy.cm2and FT: NA; for contralateral common femoral artery (CFA) approach: 207 Gy.cm2and 153 s; e.g. significantly higher than for ipsilateral CFA: 96 Gy.cm2and 78 s; for hybrid surgery: 77 Gy.cm2and 41 s; and for ipsilateral retrograde popliteal approach: 61 Gy.cm2and 53 s. The same tendency is observed for the peak skin dose (PSD) values: the highest are for brachial artery (2053 mGy) and contralateral CFA (1325 mGy) approach, followed by the ipsilateral CFA (748 mGy), hybrid surgery (649 mGy), and ipsilateral retrograde popliteal approach (566 mGy).

Conclusion:

Registered dose values and FT for the different procedures do not exceed the International Atomic Energy Agency (IAEA) proposed trigger values for patients’ follow-up for radiation-induced skin injuries. The type of vascular access has the highest negative impact on radiation dose levels and resultant KAP, PSD, and FT values. There is a significant increase of the dose values with increase of the number of inserted stents and the level of complexity. This should be considered in planning, especially for patients who undergo multiple diagnostic and therapeutic procedures.

Advances in knowledge:

This study gives a systematic understanding for patient radiation exposure in endovascular and hybrid revascularization of the lower extremities, thus far absent in the literature.

This study is about the stability conditions of a high cut slope as well as the possible measures of restoration, along the Egnatia Highway (deviation of Asprovalta). The study includes: the topographic map of the landslide and the 3-D view with the use of Geographical Information Systems, the analysis of geological and petrologie data from the samples of five core drillings, the soil mechanics laboratory tests, the determination of the causes and the landslide mechanisms and finally the slope stability analysis with «classic» methods such as Bishop, Janbu, Morgenstern-Price. A multiple repeated slope stability analysis took place in order to determinate the proper geometry (inclinations) of the slope with new benches. From the analysis of the data, the landslide restoration can be achieved with the combination of measures such as new benches geometry (proposed), surface drainage systems, retaining walls, soil nailing, geogrids and grass mat.
THE ROLE OF THE TECTONICS AND HYDROGEOLOGY AT THE TSAKONA (ARKADIA, PELOPONNESE, GREECE ) LANDSLIDE

Published: July 2018

The present paper aims to the understanding of the causes of the large-scale landslide that occurred at Tsakona area (SW Arcadia, Peloponnesus) during February 2003. This is the largest landslide that have ever effected the Greek National highway network as it entirely rubed out the new Megalopolis-Kalamata highway at a length of 200m. It took place at the western slopes of Drosovouni Mt., which exhibits an elogated shape of NE-SW direction. At the broader area of the slide three alpine formations of the Pindos unit occur which from lower to upper are: (i) the Jurassic radiolarites, (ii) the so called 1s t flysch and (iii) the Upper-Cretaceous pelagic limestones. The initial sliding took place inside the first two formations and the landslide moved more than 1,000 meters downward along the mountain slope at an E-W direction while its headscarp was near the tectonic contact between these formations and the upperlying pelagic limestones.In order to understand the causes of the landslide we carried out a detailed geological, morphotectonic, microtectonic and neotectonic study of the broader area. Additionally we constructed the structural contour map between the limestones nappe and the underlying formations. From all the aforementioned we suggested that the landslide occurred in a tectonically active area where the neotectonic deformation. Based on the above-mentioned studies, we have to mention the followings: The landslides occur in a site that the tectonic deformation is very intense. There were old landslides before the activation of the last one and before the study and construction of the highway. The constructors as well as the people that studied the area did not take into account the already existed landslides. It has to be mentioned that hydrogeological regime of the area is of great importance, as to the opposite slopes of the landslide in which occur the same formations like in the landslide area there is no landslide activity at least the last 100 years as indicated by the existing railway, due to the no occurrence of limestones above the radiolarites. From all the above mentioned it is clear that the tectonics - neotectonics affected the major area are the main factors involved to the initiation of the landslide, and the crossing of the landslide by the highway contributed to the reactivation together with the rains.

The Poliphimos cave is located in a distance of 5 km from Maronia Town, near Komotini City, in Thrace - Eastern Greece. The cave is an under development site for touristic purposes. The cave is full of beautiful stalactites and stalagmites and it is of great palaeontological and touristic interest. The cave is 2000 m long and covers an area of 10.000 m2 . The proposed visiting route is 355 m. The inside temperature is about 16 °C. For the development an integrated study was performed regarding to its geotechnical stability, together with speleological and ecological studies. In the present paper the stability conditions were studied regarding to wedge and planar failures.For this purpose, all the tectonic data were determined and recorded separately for each site in the cave and tectonic and stability diagrams were elaborated, in order to determine stability factors. A stress-strain analysis as performed in tunneling is not recommended in cases of natural caves because of the slow procedure of its formation which allows the full relief of the applied stresses. So the stability analysis of the natural cave is based only on the behavior of the blocks formed by the tectonic features. The geometry of the blocks formed by the combination of the vertical discontinuities sets with the horizontal bedding creates potential instability conditions. The instability conditions observed in situ are mainly unstable blocks falling from the roof. The main purpose, after determining any type of potential failure, was to propose the more appropriate stability methods. It is obvious that all the ordinary methods, used in underground construction, are not appropriate for use in caves.Supporting methods have to be adapted, taking into account the already existing natural stability conditions, the safety of visitors and the monumental character of the cave. According to the stability analysis of the cave, the main failure mechanism is the falling of wedges from the roof. The sides of the cave seem to be stable. For the reinforcement support of the roof, an arrangement of stainless pre-tensioned self-drilling rockbolts is suggested (2X2m and 2X2.5m, length 3m and 5m) as the optimum scenario of intervention.

Monitoring of tunnel deformation during their excavation is based on measurements of displacements of either single points or contraction of selected distances across the tunnel section. Such data, however, due to measurement errors and local effects may not be consistent with each other, and cannot describe precisely the real behavior of the ground/support shell. In the present study, a theory introduced to estimate the ground surface strain field on the basis of surveying measurements is adopted in order to estimate the average strain of tunnel sections. This theory is based on the assumption of uniform deformation across the tunnel section and of measurements affected by random errors only and uses repeated monitoring data (displacements or distance changes). The proposed theory was applied to deformation data from representative sections of the Acheloos Diversion Tunnel (Western Thessaly, Greece), subject to nearly uniform strain. Mean strain changes were estimated for various time intervals following the excavation. About one year after the excavation, maximum horizontal strain of -1.3%, accompanied by practically negligible vertical strain, was computed.

Seawater intrusion problems are recorded in coastal aquifers, which constitute the main sources of drinking water and agricultural irrigation in many countries. The aim of this work is to describe the evolution of the salinity distribution by seawater intrusion, based on results from chemical analyses, of 29 groundwater samples in the NWAchaia area (Peloponnesus, Greece). The study of these data indicates that aquifer waters in large part of area reflect salinization related to seawater intrusion. The occurrence of Ca-CI hydrochemical types of groundwater indicates active seawater intrusion. Cation exchange is the most noticeable hydrogeochemical process in the movement of the saline front in the coastal aquifer. Geographical distribution of Careact index was mapped. The areas with advance or decline of the seawater intrusion front are defined from this map.
SIMULATION OF SEA WATER INTRUSION IN THE PLAIN OF ARGOS WITH ADVECTION - DISPERSION MODEL
Authors: Γιαννουλόπουλος Π.
Published: July 2018

The plain of Argos, southern Greece, is perhaps the first region in Greece where sea water intrusion in groundwater was noticeably observed since late fifties. Observed chloride concentrations, are mostly less than 1500 mg/l, in the affected zone, exhibiting smooth variations. Also, relevant water quality data, show that sharp fronts are not occurring. Thus, the transport of chlorides is assumed to be governed by advection and dispersion mechanisms rather than density dependent transport. In this paper the application of a distributed numerical model, based on advective and dispersive - chloride transport is described. Hence, the mathematical model of a "homogeneous fluid" and the "tracer" approach has been assumed rather that the "general" approach of the "heterogeneous fluid". This code has successfully replicated the measured concentrations of the calibration period (1964-69) and also the pertinent concentrations of the validation period (1969-750). In predictive simulation, a scenario of chloride flushing by natural recharge, without any pumping, was tested and it was calculated that rehabilitation period could be at least as long as twenty years. The weakness of this model involves both errors of conceptual model and numerical errors. The major conceptual problem is the lack of knowledge of pumping distribution, which constitutes the driving force of salinization, while numerical errors are mainly attributed to mass balance errors introduced in the Eulerian - Lagrangian implementation of the numerical model.
APPLICATION OF THE MATHEMATICAL MODEL MODFLOW ON A KARSTIC AQUIFER: THE CASE OF VIOTIKOS KIFISOS BASIN

Published: July 2018

MODFLOW is a very well verified code of mathematical modeling for simulation of saturated groundwater flow in porous medium. Groundwater flow simulation in discontinuity media (i.e. media characterized by dominance of secondary and tertiary porosity as opposed to primary porosity), such as karstic aquifers, utilizing specialized models is problematic. Due to existing impedes the use of the conventional model MODFLOW was attempted for the simulation of the karstic system of the Viotikos Kifisos river aiming predominantly at assessing the potential, restrictions, particularities and conditions under which such a modelling code could be implemented, especially when relatively restricted volume of raw data is available. Compilation and calibration of the model suggest that MODFLOW may in general be implemented and can provide useful results. As in every mathematical model, knowledge of the assumptions made and the intrinsic restrictions involved is required, along with in-depth evaluation of its capabilities. The mathematical model of Viotikos Kifisos basin forms a valuable tool for management of its water resources and study of regional groundwater evolution.

Authors: Σταμάτης Γ. , Μιγκίρος Γ.
Published: July 2018

Ossa mountain is an area of great hydrogeological interest due to its geological structure. In this Paper the massive lithological formations and the tectonic structure are presented in relation to the forming of Ossa hydrogeological conditions. The groundwater flow directions are directly depended on the dominant anticline structure of Ossa mountain. The observing of field measurements as well as the processing of aerial photos reviled some transversal zones of high fracture. A great amount of groundwater is moving through some main zones of NNE direction as well as some secondary zones of N-S and E-W directions. A direct relationship is shown between tectonical structures and springs. The hydrochemical character of aquifers are presented through chemical analysis. Specifically, the detected Ca-HC03 reveals waters from karstic formations, while Ca-Mg-HC03, Ca-Mg-Na-HC03 reveals origins from metamorphic formations.
Ψηφιακή επιτέλεση και μεταανθρωπιστική ανθρωπολογία

Η χρήση ψηφιακών τεχνολογιών στις επιτελεστικές τέχνες τις τελευταίες δύο δεκαετίες έχει πυροδοτήσει μια έντονη συζήτηση, ιδιαίτερα στο πεδίο των επιτελεστικών σπουδών, γύρω από το ζήτημα της οντολογίας της επιτέλεσης. Αυτή η συζήτηση αναπαράγει σε μεγάλο βαθμό δυϊσμούς μεταξύ νου/σώματος, φύσης/πολιτισμού και ανθρώπου/τεχνολογίας, οι οποίοι δεν επαρκούν για την κατανόηση των πολλαπλών εμπειριών των ίδιων των συμμετεχόντων σε συγκεκριμένες ψηφιακές επιτελέσεις. Εκκινώντας από τους θεωρητικούς και μεθοδολογικούς προβληματισμούς που θέτει η μεταανθρωπιστική ανθρωπολογία, σ’ αυτό το κείμενο διερευνώ τους τρόπους με τους οποίους η αμφισβήτηση των παραπάνω δυϊσμών μπορεί να εμπλουτίσει τη μελέτη της ψηφιακής επιτέλεσης αλλά και της σχέσης των ανθρώπων με το περιβάλλον τους στο πλαίσιο των αναδυόμενων ψηφιακών κουλτούρων.
Πορνεία και «ανελευθερία» στον Μεσοπόλεμο

Στο άρθρο αυτό στοχεύω ν’ αναδείξω πώς στον Μεσοπόλεμο δημιουργήθηκε σταδιακά ένας ιατρικός λόγος με στόχο τον σωματικό και ηθικό σωφρονισμό του πληθυσμού, προσπαθώντας με αυτό τον τρόπο να κάνω σαφές πώς μέσα σε αυτό το πλαίσιο το σώμα της «κοινής γυναίκας» χρησιμοποιείται από το κράτος στην εισαγωγή βιοεξουσιαστικών/βιοπολιτικών μηχανισμών ελέγχου στον πληθυσμό, με πρόσχημα την αναγκαιότητα της εξυγίανσης της κοινωνίας από τα αφροδίσια νοσήματα. Είναι σε αυτό το σημείο που στην πραγματικότητα εδραιώνεται μια «αλήθεια» κινδύνου που έπειθε ακόμη και τα αστικά φεμινιστικά κινήματα της εποχής για την ασυμβατότητα της «ελευθεριότητας» σε μια πολιτισμένη κοινωνία.
