“Red eye” is the most common ocular manifestation seen by primary care physicians. Most cases are connected with benign diseases, yet some may require emergent ophthalmologic intervention or herald a life‐threatening systemic disorder. Scleritis usually manifests as severe and painful red eye and is frequently associated with systemic vasculitis. Herein, we report the case of an 81‐year‐old man with microscopic polyarteritis presenting with rapidly progressive glomerulonephritis, diffuse alveolar hemorrhage, and bilateral painless scleritis. Our experience may remind clinicians of the importance of “red eye” as a clue in the early diagnosis of systemic vasculitis, even in the absence of pain.

Authors: Agudelo Restrepo Cristian Manuel , Díaz Castillo Oscar Daniel , García Vera Yimy Edisson
Published: December 2016

El cambio climático es actualmente una gran preocupación para la sociedad humana, en particular debido a nuestra alta dependencia a los combustibles fósiles. Una cantidad considerable de esfuerzo investigativo se centra en los sistemas solares fotovoltaicos (PV). En dichos sistemas, la eficiencia en la conversión de energía es un tema de investigación activa y múltiples enfoques se están desarrollando para resolver este problema. Uno de estos enfoques son los sistemas de seguimiento solar, donde los paneles se mueven con respecto al sol con el fin de captar la máxima radiación solar directa. En este trabajo se propone un sistema de seguimiento solar fotovoltaico de un eje empleando como mecanismo de acción un servomotor y luego se realiza la comparación de su eficiencia energética con respecto a una instalación fotovoltaica fija. El sistema fue probado en la ciudad de Fusagasugá, Colombia, que se encuentra en una región tropical.

Increased competition caused by globalization has led to philosophical changes in private and public businesses. This change has affected educational institutions and they have needed dynamic, innovator and transformational tools in order to survive in competitive environment. The universities defined as “3rd GU” need commercialization, network among universities, close co-operation among institutions and entrepreneurship as well as intellectual and innovative changes. In this regard, the aim of the research is formed by the analysis of “Entrepreneur University” concept from the perspective of the academicians that served at managerial positions at the universities in Turkey and the discussion of these universities’ economical situation for being ready about 3GU concept. In line with these purposes, we will give place to ideas of 283 academicians served in Turkish universities and then we will try to analyze in macro-economic dimension for comparing to their expectations and the truth that’s happen in real life. Although there are 183 universities depending on The Council of Higher Education in Turkey, the number of universities used in our study has been limited by randomly chosen 18 universities for forming an appropriate conceptual framework. ÖzetKüreselleşme ile gelen artan rekabet özel ve kamu işletmelerinde felsefi değişimlere neden olmuştur.

Is There a Role for Higher Education Institutions in Improving the Quality of First Employment?
Authors: McGuinness Seamus , Whelan Adele , Bergin Adele
Published: December 2016

This paper examines the potential role of higher education institutions in reducing labour market mismatch amongst new graduates. The research suggests that increasing the practical aspects of degree programmes, irrespective of the field of study, will reduce the incidence of initial mismatch. In terms of routes into the labour market, higher education work placements with the potential to develop into permanent posts and the provision of higher education job placement assistance were found to have substantial impacts in reducing the incidence of graduate mismatch. The use of private employment agencies was found to significantly heighten the risk of subsequent mismatch.
Life Cycle Assessment of a New Feed Production Obtained by Wasted Flour Food Collected from the Distribution and Retail Phases
Authors: Mosna David , Vignali Giuseppe , Bottani Eleonora , Montanari Roberto
Published: December 2016

This study assesses the suitability of flour food products wasted during the distribution phase to be used as raw material for the production of animal feed. Landfill is nowadays the most adopted end of life option for flour food products. Nonetheless, by setting up a specific sorting system, it would be possible to separate the wasted food from its packaging and to recover both of them. In this latter case, food waste could be better valorised, by diverting it to alternative channels, such as anaerobic digestion or animal feeding. In this study, the environmental performance of two valorisation scenarios for floor food waste intended to be used to produce animal feed were analysed using the Life Cycle Assessment methodology. The new scenarios are compared with one another and with the traditional feed production. Results of the study show that the new scenarios lead to environmental benefits for all the considered impact categories.

Published: December 2016

The purpose of the study was to determine the effects of different temperatures (40, 50 and 60 °C) and air velocities (1 and 2 m/s) on shrinkage, porosity, pore size distribution, color and microstructure of orange peel. Empirical models were also proposed to predict shrinkage and porosity as a function of moisture. A strong negative correlation was determined between moisture and shrinkage. Air temperature had no significant impact on the final shrinkage and porosity values. During drying, porosity of the samples first increased until a critical value, at which point further decrease in moisture resulted in collapse of pores. The porosity of the orange peel was correlated with moisture by a third-order polynomial. Pore size distribution curve of raw sample showed two major peaks, a wider and a sharper peak at around 19.8 and 7.18 μm, respectively. After drying, the peaks became shorter and the curve shifted to the left, indicating that the amount of pores and their diameter decreased. The SEM analysis revealed that at extreme process conditions, the orange peel surface was cracked and the characteristic distribution of the waxy components was obstructed.

Authors: Chen Wan , Liu Gaoqiang , Yang Huandong , Zhou Huabin , Yang Hailong
Published: December 2016

The effects of deproteinization and drying methods on the antioxidant activities and physiochemical properties of C. militaris polysaccharide were evaluated. The results showed that the IC50 of crude polysaccharide (CMP)was similar with that of deproteined polysaccharide by sevag (CMP-D-S), but significant higher (p < 0.05)than that of deprotiened polysaccharie by enzyme (CMP-D-E)on DPPH· scavenging. The IC50 of CMP was significant higher (p < 0.05)than that of CMP-D-S and CMP-D-E on OH· scavenging. Deproteinization by sevag or enzymatic method could not improve the antioxidant activity of C. militaris polysaccharide. However, drying methods influenced the antioxidant activities of C. militaris polysaccharide. Polysaccharide dried by freeze drying (CMP-F)showed respectively 55.47 % and 61.99 % higher OH· scavenging capacity on IC50 than that dried by hot air drying (CMP-H)and spray drying (CMP-S). The IC50 of CMP-F was 56.23 % higher than that of CMP-S, but similar with that of CMP-H on ABTS· scavenging. The reducing power of CMP-F was respectively 20.10 % and 27.25 % higher than that of CMP-H and CMP-S at 6 mg/mL. Spectroscopy analysis showed the dried CMPs were similar in IR and UV absorption. However, the monosaccharide ratio of CMP was changed by drying techniques. Morphological analysis showed that CMP-F consisted mainly of fluffy powder with rough and porous surface, CMP-S was spherical particle with smooth surface, and CMP-H was pyknotic and similar to anomalistic stones. Freeze drying was a recommendable method for antioxidant polysaccharide preparation from C. militaris.
Diagnosis and therapy of osteoporosis in geriatric trauma patients: an update
Authors: Schray Deborah , Stumpf Ulla , Kammerlander Christian , Böcker Wolfgang , Neuerburg Carl
Published: December 2016

Demographic changes confront clinicians with an increasing number of orthogeriatric patients. These patients present with comorbidities, which force their surgeons to take into consideration their medical condition. A major risk factor for fractures in orthogeriatric patients is osteoporosis in combination with frailty. To prevent subsequent fractures in these patients, we need to pay attention to adequate osteoporosis treatment in orthogeriatric patients. There is a huge treatment gap. In Germany, 77% of patients with osteoporosis are not treated adequately. Even after fragility fractures, a low percentage of patients receive a specific osteoporosis therapy. Secondary prevention is of great importance in the treatment of these patients. Diagnostics and treatment should be already initiated with the admission to the hospital. Treatment decisions need to be made individually based on the risk profile of the patients. After discharge, it is important to involve the patients’ general practitioners and to follow up on patients regularly to improve their compliance and to ensure adequate therapy. Establishing a fracture liaison service helps coordinating osteoporosis treatment during hospitalization and after discharge. Subsequent fractures can be reduced; therefore, it is an effective service for secondary prevention. The present article provides an overview of how an efficient identification and subsequent treatment of osteoporosis can be achieved in aged trauma patients.
Pirimicarb, an aphid selective insecticide, adversely affects demographic parameters of the aphid predator Hippodamia variegata (Goeze) (Coleoptera: Coccinellidae)
Authors: Rahmani Shima , Bandani Ali R.
Published: December 2016

Demographic toxicology is recommended for toxicity determination of the long term effects of a pesticide since it gives a more accurate and efficient measure of the effect of a pesticide. Thus, in the current study the sublethal effects of pirimicarb (carbamate insecticide) two concentrations of LC30and LC10were used against third instar larvae of Hippodamia variegata (Goeze) in order to determine the effects of the pesticide on demographic parameters of the predator under laboratory conditions. Results showed that pirimicarb did not affect individual life parameters such as development time of larva, pupa, adult longevity, female and male longevity, adult preoviposition period (APOP), and total preoviposition period (TPOP). However, population parameters such as intrinsic rate of increase (r), net reproductive rate (R0), mean generation time (T), and finite rate of increase (λ) was affected by sublethal treatment. For example, intrinsic rate of increase (r) was 0.18 day-1in the controls but it was 0.13 and 0.14 day-1in the treated insects with LC10and LC30concentrations, respectively. Also, there were significant differences between mean generation time (T) of the treatments and the controls i.e. mean generation time of the controls was 29.03 days while mean generation time in the two treatments of LC10and LC30was 33.93 and 31.66 days, respectively. The finite rate of increase was also significantly affected by sublethal effects of the pesticide. The results showed that pirimicarb, even at low concentrations, has potential to adversely affect the predatory ladybird, therefore care should be taken when this insecticide is used in the Integrated Pest Management (IPM) program.
Aphids of the genus Diuraphis caught by Johnson suction trap in Poznań, Poland

Published: December 2016

In 1973-2011 in Poznań, aphid catches were carried out using Johnson’s suction trap. Since then the suction trap located at the Institute of Plant Protection - National Research Institute in Poznań has continuously recorded the daily and seasonal dynamics of aphid flights. The collected results has been used to establish one of the largest databases of this type in Europe. The data also allow tracking changes in aphid biodiversity under the changing climatic conditions. Three aphid species of Diuraphis spp. were identified: D. muehlei (Börner, 1950) - in 1974, D. bromicola (Hille Ris Lambers, 1959) - in 1988, D. noxia (Kurdjumov, 1913) - in 2003 as a result of systematic and long-term aphid collections. The occurrence of D. noxia presents a particular risk to cereal crops in Poland. This expansive aphid species that originates from Asia and the Mediterranean is a vector of Barley yellow dwarf viruses (BYDV), and has become one of the most important pest of wheat and barley in the world. Changes in climatic conditions that have been observed in recent years in Poland such as hot summer, long and warm autumn, mild winter seem to be optimal for occurrence and development of aphid species from warmer parts of Europe.
An overview of lithotype associations of Miocene lignite seams exploited in Poland
Authors: Widera Marek
Published: December 2016

Currently, three stratigraphically distinct lignite seams of Early to Middle Miocene age are exploited in Poland, namely the third Ścinawa lignite seam (ŚLS-3), the second Lusatian lignite seam (LLS-2) and the first Mid-Polish lignite seam (MPLS-1). All of these are composed of numerous macroscopically distinguishable layers defined as lignite lithotypes. In the present paper, the lithotypes of Polish lignites are grouped into seven major lithotype associations that originated in various types of mire. Therefore, an approximate reconstruction of mire type can be based on lignite lithotypes. Within the Polish lignite seams examined, the commonest in order of importance are: xylodetritic (XDL), detroxylitic (DXL), detritic (DL) and xylitic (XL) lithotype associations, mostly with a massive (m) or horizontal (h) structure. They are particularly dominant in lignite opencasts belonging to the Konin and Adamów mines. However, in the lowermost seams at the Turów and Bełchatów mines, a substantial part of the seams comprises the bitumen-rich (BL) lithotype association. These seams also lignite lithotypes that in large quantities have a gelified (g) and/or nodular (n) structure. In contrast, lignites from the Sieniawa mine are characterised by an admixture of the best-developed lithotype associations of both fusitic (FL) and weathered (WL) lignites. Moreover, the vast majority of these lignites have a folded (fo) and/or faulted (fa) structure, because they were completely deformed by glaciotectonics.
Representatives of the family Actinostromatidae (Stromatoporoidea) in the Devonian of southern Poland and their ecological significance
Authors: Wolniewicz Paweł
Published: December 2016

Stromatoporoids of the family Actinostromatidae are common constituents of Givetian to Frasnian (Devonian) organic buildups. The species-level structure of actinostromatid assemblages from the Devonian of southern Poland is described in the present paper, with special emphasis on ecological factors that influenced species composition of the communities. Nine species of the genera Actinostroma and Bifariostroma are distinguished. Members of the family Actinostromatidae predominated in stromatoporoid assemblages within lower Frasnian carbonate buildup margins. The most diverse actinostromatid faunas were found within the middle Givetian Stringocephalus Bank, in the upper Givetian-lower Frasnian biostromal complex and in the lower Frasnian organic buildups. Species-level biodiversity was lowest within detrital facies which surrounded the Frasnian carbonate buildups. Species of Actinostroma with well-developed colliculi are commonest within the middle Givetian to early Frasnian coral-stromatoporoid biostromal complexes, whereas species with strongly reduced colliculi predominate early-middle Frasnian organic buildups. The skeletal structure of actinostromatids reflects environmental changes, documenting a transition from species with thin, close-set pillars and widely spaced laminae (common in the middle Givetian) to those with long, thick pillars and megapillars (in Bifariostroma), which were predominant during the early and middle Frasnian. The distribution of growth forms among species reveals a significant intraspecific variation. Species of Actinostroma can be either tabular or low domical, depending on the palaeoenvironmental setting. Thus, the present study confirms that stromatoporoid morphology was influenced by environmental conditions.
Older Knowledge Workers as the Labour Market Potential (Slovenia versus Finland)
Authors: Zupančič Magda
Published: December 2016

This article refers to the challenge of demographic changes gaining attention in many developed countries. The European Union recognized the need to activate older knowledge workers, who are underrepresented and pushed out of the labour market or are inadequately motivated to continue their employment for various reasons, despite their accumulated knowledge and experiences. EU member states respond differently to their ageing, with more or less successful national policies. This article is based on research of the labour market development for older knowledge workers in Slovenia compared to the Finnish age management policy at the end of the 1990s that successfully increased Finnish older knowledge workers’ employment through focused and holistic measures. Slovenia stagnated in the same period due to a lack of holistic solutions-a situation that continues today. The results and deficiencies of past bad and good practices in these two compared EU member states might offer some further reflections on possible steps to follow or avoid regarding active ageing solutions in the EU.
Conceptual and Methodological Issues in Studying Alcohol's Harm to Others1
Authors: Room Robin , Laslett Anne-Marie , Jiang Heng
Published: December 2016

While there is a longer history of concern about alcohol's harm to others, researchers' interest has intensified in the last few years. The background of variation in concern over time in different societies is outlined. Three main traditions of research have emerged: population survey studies of such harm from the perspective of the ‘other’; analysis of register or case-record data which includes information on the involvement of another's drinking in the case; and qualitative studies of interactions and experiences involved in particular harms from others' drinking. In the course of the new spate of studies, many conceptual and methodological issues have arisen, some of which are considered in the paper. The diverse types of harms which have been studied are discussed. The social and personal nature of many of the harms means they do not ft easily into a disability or costing model, raising questions about how they might best be counted and aggregated. Harm from others' drinking is inherently interactional, and subject to varying definitions of what counts as harm. The attribution to drinking, in the usual situation of conditional causation, is also subject to variation, with moral politics potentially coming into play. For measurement and comparison, account needs to be taken of cultural and individual variations in perceptions and thresholds of what counts as a harm, and attribution to alcohol. The view from the windows of a population survey and of a response agency case register are often starkly different, and research is needed, as an input and spur to policy initiatives, on what influences this difference and whether and how the views might be reconciled.

Published: December 2016

Aims

As part of the WHO Harm from others' drinking project, Thailand, Sri Lanka, India, Chile, Nigeria and Vietnam undertook scoping studies to examine: which service agencies in low and middle income countries responded to people affected by others' drinking; how commonly key informants from these agencies indicated alcohol was part of the problems they managed; and whether any routine reporting systems collected information on alcohol's harm to others (AHTO) and the types and examples of harms experienced across the six countries.

Methods

Researchers synthetised within country peer-review literature, reports, news and agency website information. Additionally, researchers interviewed key informants to investigate current structures, functions and practices of service agencies, and in particular their recording practices surrounding cases involving others' drinking.

Results

111 key informants agreed to participate from 91 purposively selected agencies from health, social protection, justice and police, and ‘other' sectors. National and provincial level data, as well as state-run and civil society agency data were collected. Diverse service response systems managed AHTO in the different countries. A large range in the percentage of all cases attributed to AHTO was identified. Case story examples from each country illustrate the different responses to, and the nature of, many severe problems experienced because of others' drinking.

Conclusions

AHTO was a major issue for service systems in LMIC, and significantly contributed to their workload, yet, very few recording systems routinely collected AHTO data. Recommendations are outlined to improve AHTO data collection across multiple sectors and enable LMIC to better identify and respond to AHTO.
How Does it Fit? Multiple Religious Belonging, Spiritual but not Religious, and The Dances of Universal Peace
Authors: Mercadante Linda
Published: December 2016

Are people who call themselves “spiritual but not religious” (SBNR) actually practicing multiple religious belonging (MRB)? Or are “multiple religious participation” or “multiple religious involvement” better designations? This article suggests that “multiple religious orientation” fits their practices better. But a subset of the SBNR movement, The Dances of Universal Peace, is used as a case study in straddling the boundaries between MRB and SBNR. It also suggests ways to understand and locate the practices of SBNRs within the MRB discussion.
Perils and Possibilities of Multiple Religions Belonging: Test Case in Roman Catholicism
Authors: Feldmeier Peter
Published: December 2016

After reviewing various forms of multiple religious belonging, the author argues for the necessity of preliminary first principles, primarily coming from a considered form of a theology of religions. While an exclusivist theology would not allow multiple belongings, forms of inclusivism, pluralism, and postmodern mutualism provide possibilities. Since Roman Catholicism takes the most typical inclusivist position and has documented authoritative magisterial texts regarding Christianity and the religious other, the author makes a test case from the official Roman Catholic position. These he uses to guide theological possibilities and limitations. Ultimately, what he argues is that the Catholic position is not completely coherent and itself weaves some pluralist and postmodern principles into its supposedly rigid inclusivist position. As a test case, it shows the problems in creating a complete and absolute paradigm regarding Christianity‘s relationship with other religions. He finally argues for a modestly faithful form of Catholic theology that allows for some forms of multiple religious belonging, but also shows how full-fledged multiple identities are fraught.
ErasuCrypto: A Light-weight Secure Data Deletion Scheme for Solid State Drives
Authors: Liu Chen , Khouzani Hoda Aghaei , Yang Chengmo
Published: December 2016

Securely deleting invalid data from secondary storage is critical to protect users’ data privacy against unauthorized accesses. However, secure deletion is very costly for solid state drives (SSDs), which unlike hard disks do not support in-place update. When applied to SSDs, both erasure-based and cryptography-based secure deletion methods inevitably incur large amount of valid data migrations and/or block erasures, which not only introduce extra latency and energy consumption, but also harm SSD lifetime.

This paper proposes ErasuCrypto, a light-weight secure deletion framework with low block erasure and data migration overhead. ErasuCrypto integrates both erasurebased and encryption-based data deletion methods and flexibly selects the more cost-effective one to securely delete invalid data. We formulate a deletion cost minimization problem and give a greedy heuristic as the starting point. We further show that the problem can be reduced to a maximum-edge biclique finding problem, which can be effectively solved with existing heuristics. Experiments on real-world benchmarks show that ErasuCrypto can reduce the secure deletion cost of erasurebased scheme by 71% and the cost of cryptographybased scheme by 37%, while guaranteeing 100% security by deleting all the invalid data.

Published: December 2016

The majority of people across the globe rely on telephony networks as their primary means of communication. As such, many of the most sensitive personal, corporate and government related communications pass through these systems every day. Unsurprisingly, such connections are subject to a wide range of attacks. Of increasing concern is the use of metadata contained in Call Detail Records (CDRs), which contain source, destination, start time and duration of a call. This information is potentially dangerous as the very act of two parties communicating can reveal significant details about their relationship and put them in the focus of targeted observation or surveillance, which is highly critical especially for journalists and activists. To address this problem, we develop the Phonion architecture to frustrate such attacks by separating call setup functions from call delivery. Specifically, Phonion allows users to preemptively establish call circuits across multiple providers and technologies before dialing into the circuit and does not require constant Internet connectivity. Since no single carrier can determine the ultimate destination of the call, it provides unlinkability for its users and helps them to avoid passive surveillance. We define and discuss a range of adversary classes and analyze why current obfuscation technologies fail to protect users against such metadata attacks. In our extensive evaluation we further analyze advanced anonymity technologies (e.g., VoIP over Tor), which do not preserve our functional requirements for high voice quality in the absence of constant broadband Internet connectivity and compatibility with landline and feature phones. Phonion is the first practical system to provide guarantees of unlinkable communication against a range of practical adversaries in telephony systems.
Graphene via Molecule-Assisted Ultrasound-Induced Liquid-Phase Exfoliation: A Supramolecular Approach
Authors: Eredia Matilde , Ciesielski Artur , Samorì Paolo
Published: December 2016

Graphene is a two-dimensional (2D) material holding unique optical, mechanical, thermal and electrical properties. The combination of these exceptional characteristics makes graphene an ideal model system for fundamental physical and chemical studies as well as technologically ground breaking material for a large range of applications. Graphene can be produced either following abottom-uportop-downmethod. The former is based on the formation of covalent networks suitably engineered molecular building blocks undergoing chemical reaction. The latter takes place through the exfoliation of bulk graphite into individual graphene sheets. Among them, ultrasound-induced liquid-phase exfoliation (UILPE) is an appealing method, being very versatile and applicable to different environments and on various substrate types. In this chapter, we describe the recently reported methods to produce graphene via molecule-assisted UILPE of graphite, aiming at the generation of high-quality graphene. In particular, we will focus on the supramolecular approach, which consists in the use of suitably designed organic molecules during the UILPE of graphite. These molecules act as graphene dispersion-stabilizing agents during the exfoliation. This method relying on the joint effect of a solvent and ad hoc molecules to foster the exfoliation of graphite into graphene in liquid environment represents a promising and modular method toward the improvement of the process of UILPE in terms of the concentration and quality of the exfoliated material. Furthermore, exfoliations in aqueous and organic solutions are presented and discussed separately.

Authors: Wiśniewski Szymon
Published: December 2016

The article seeks to analyse the accessibility of hospital healthcare to inhabitants of Łódź voivodeship in 2015. The analysis comprises all the communes of the Łódź region as well as those of the neighbouring voivodeships from which the theoretical time of reaching hospitals in Łódź voivodeship does not exceed the maximum time assumed in the research. Accessibility was determined in reference to 51 hospitals, assuming that their ‘attractiveness’ was related to the number of permanent beds they offered. The research was conducted using the three-step floating catchment area method (3SFCA).

Childhood cancer remains the leading cause of illness-related death in childhood, but significant advances in survival have been made in the past 40 years. This review looks at the neuropsychiatric presentations, psychosocial and treatment-related issues that arise in children with brain tumors.
Hyperostotic sphenoid wing meningioma en plaque: proptosis management
Authors: Zakaria Wael K. , Taha Ahmed N.
Published: December 2016

Background: En plaque sphenoid wing meningioma is morphological unique in comparison with other intracranial meningiomas, characterized by a carpet-like usually small soft tissue component which invade the dura and extensively involve the bone specially the sphenoid wing and orbit causing significant hyperostosis. Patients & Methods: A retrospective analysis of the clinical data, neuro-radiological features, and operative techniques of eighteen patients underwent transcranio-orbital approach sphenoid wing meningioma presented with proptosis during the period from September 2011 to April 2014 in the neurosurgery department, Mansoura University. Patients age ranged from 38 years to 54 years and there was sex males and twelve females. Chief complaints were progressive proptosis and visual acuity deficits. All patients were operated up on using a fronto-temporal approach with orbital decompression. The extent of tumor resection and postoperative complications were investigated. Results: Total removal was achieved in fourteen cases (77.8%) over a mean follow-up period of 36 months. Pathological examination showed that twelve patients (66.67%) were meningothelial meningiomas. After surgery, proptosis improved in all patients, visual acuity improved in fifteen patients (83.3%). Cerebrospinal fluid leakage was found in one patient. There were no operation-related deaths or other significant complications. Four patients had residual tumor (22.2%); two of them underwent surgical re-attack of the tumor and the other two cases were sent for gamma knife radio-surgery. Conclusions: Sphenoid wing meningioma en plaque, mainly meningothelial meningiomas, are characterized by the associated bony hyperostosis that gives them a distinct radiological appearance. The bony hyperostosis is of neoplastic nature and is responsible for many of the clinical manifestation of such tumors and hence should be totally drilled to achieve cure and avoid recurrence. Extensive tumor removal is crucial for correction of proptosis and adequate visual decompression to achieve satisfactory cosmetic and functional outcome.

Background: Intracranial hemorrhagic complications are unusual after diagnostic lumbar puncture. Case report: A diagnostic lumbar puncture was performed in a 55 year-old male for acute bacterial meningitis workup. Immediately after the procedure he developed intense headache and a head Computed Tomography (CT) was done which identified an acute subdural fluid collection. No surgical management was offered and conservative medical follow-up was indicated. Conclusion: The occurrence of a headache with red flags after a lumbar puncture may suggest the possibility of an acute subdural hematoma.
Thoracic spine stab injury with pneumocephalus and pneumorrhachiasis: a unique case report and review of literature
Authors: Kumar Rakesh , Mittal Radhey Shyam , Gandhi Ashok
Published: December 2016

Trauma to skull base or sinus is the most common cause of pneumocephalus. There are only few published reports of traumatic pneumocephalus secondary to penetrating injury of upper spine, epidural anaesthesia and lumber puncture. Till date only one case of pneumocephalus and pneumorrhachiasis after thoracic spine stab injury is reported in available English literature that too associated without any neurological deficit. To our knowledge, this is the first reported case of pneumocephalus and pneumorrhachiasis after thoracic spine stab injury with asymmetrical, incomplete spinal cord injury leading to neurological deficit in the patient. The management protocol of such injuries needs to be individualised for better outcome.

Wasting of muscle is usually a feature of lower motor neuron pathology, astonishingly parasagittal intracranial lesion affecting parietal lobe of cerebral hemisphere may be associated with Wasting of contralateral calf muscle. It can be associated with spastic foot drop. Foot drop is a common neurological state presenting with weakness involving anterior tibialis muscle causing inability of foot extension. Foot drop is commonly caused lower motor neuron disease pathology and a common cause includes L4-L5 radiculopathy or peroneal peripheral neuropathy. However, extremely rarely can be caused by intracranial pathology e.g. falcine meningioma and represents an important localization sign. Authors report an interesting case of calf muscle wasting caused by falcine meningioma, which may escape detection to remind rare but extremely important neurological localizing sign and ask for through and further neurological evaluation prior to concluding a final neurological diagnosis.

Published: December 2016

The paper presents the analysis of the II Underground Line construction’s impact on the Warsaw Scarp with the use of the electrical resistivity imaging (ERI, also known as the electrical resistivity tomography) and further total station position measurements.The underground passes under the scarp perpendicular in the area of Dynasy Street 6, in Down-town district.The electrical resistivity imaging was performed for recognition of the geological structure and a potential land slide surface or zone.The gradient system was used during the prospection. In these analyses, the longitudinal section was 40 m long, and the depth of survey amounted to 6 m. In the case of the 200 m long transverse section, the resulted depth of survey was 30 m.The geophysical image of the longitudinal section,does not contain loosening soil zones,which could indicates lip surface.Next, total station measurements, which were tied to the archival geodetic observations’ results, were carried out. The aim of the measurements was to verify the activity of the horizontal and vertical displacements. The TBM excavation process led to summary vertical displacements up to approx. 24 mm and horizontal displacements amounting to approx. 13 mm. To sum up, the current land surveys reveals minor under ground line’ s construction impact on the scarp displacement. Nevertheless, the sensitive urban environment requires further monitoring, especially that the operation loads can result in displacement rate change.
Crosslinguistic influence on headedness of novel English compounds
Authors: Onysko Alexander
Published: December 2016

This article explores the hypothesis that bilingual knowledge of different compounding patterns can influence the interpretation of a set of novel English noun-noun compounds. The focus of the study is on bilingual speakers who are fluent in two typologically diverse languages: te reo Māori (postmodifying) and English (premodifying). A comparison of bilingual and monolingual participant groups indicates that Māori-English bilingual speakers more frequently rely on the Māori structure of left-headed compounding in their meaning interpretation of English compounds. The implications of these results are discussed in terms of the cognitive process of transfer and additional means of meaning association in bilingual speakers.
Blocking PAR2 alleviates bladder pain and hyperactivity via TRPA1 signal
Authors: Chen Daihui , Liu Nian , Li Mao , Liang Simin
Published: December 2016

Bladder disorders associated with interstitial cystitis are frequently characterized by increased contractility and pain. The goals of this study were to examine 1) the effects of blocking proteinase-activated receptor-2 (PAR2) on the exaggerated bladder activity and pain evoked by cystitis and 2) the underlying mechanisms responsible for the role of PAR2 in regulating cystic sensory activity. The protein expression of PAR2 was amplified in rats with cystitis by inducing it with systemic administration of cyclophosphamide (CYP) as compared with control rats. Blocking PAR2 by intrathecal infusion of PAR2 antagonist FSLLRY-NH2 attenuated bladder hyperactivity and pain. In addition, blocking PAR2 attenuated the transient receptor potential A1 (TRPA1) signal pathway, whereas inhibition of the TRPA1 decreased bladder hyperactivity and pain. The data revealed specific signaling pathways leading to CYP-induced bladder hyperactivity and pain, including the activation of PAR2 and TRPA1. Inhibition of these pathways alleviates cystic pain. Targeting one or more of these signaling molecules may present new opportunities for treatment and management of overactive bladder and pain often observed in cystitis.

Authors: Květoň Josef , Eliáš Jan
Published: December 2016

The contribution presents simulations on concrete specimens. The discrete meso-scale particle model with random geometry based on Voronoi tessellation is used. The model was enhanced with dynamic solver based on implicit Newmark method. Model is tested on cantilever beam loaded by a force at the free end to verify the ability of the model to simulate the dynamic behavior of a simple linear elastic material. Results computed with different time discretization and model settings are compared. The behavior of the model in nonlinear regime is investigated on concrete specimens loaded at different displacement rates. The constitutive law used within this contribution is insensitive to strain rate.
