    Fly-ash which is being produced as a result of coal combustion provides serious environmental problem, especialy if it is hardly remediated. Kosovo powerplants since 1963 have formed huge fly-ash dumps, with over than 200,000 t of fly-ash, which provides seriou environmental problem now. Afact that fly-ash of Kosovo powerplants is alkaline, with relatively high content of CaO, recommends it as a material which can be successfuly used in melioration of acid soils.Elektrofilterski pepeo (EF) koji nastaje kao proizvod sagorevanja uglja u elektranama predstavlja ozbiljan ekološki problem, naročito ako je slabo rekultibilan. Kosovske termoelektrane su tokom vremena, od 1963. godine do danas, formirale ogromne deponije EF pepela, čija težina danas iznosi 200.000 tona i predstavljaju ozbiljan ekološki problem. Činjenica da je EF pepeo kosovskih termoelektrana alkalne reakcije, sa relativno visokim sadržajem CaO, preporuka je da se, kao material, može koristiti za uspešnu popravku kiselih zemljišta, što je i cilj ovog rada

    -VASc score with unfavourable functional outcome (defined as a 30-day modified Rankin Scale [mRS] ≥3) in patients presenting with acute ischemic stroke (AIS), and examined whether the addition of blood biomarkers (troponin I [TnI], fibrinogen, C-reactive protein [CRP]) affects the model discriminatory ability.We conducted an observational single-centre study of consecutive patients with AIS. All patients were admitted to hospital within 24 hours from the neurological symptoms onset.-VASc and TnI or TnI, fibrinogen and CRP (z statistic 0.369, p = 0.7119; integrated discrimination index 0.00801 and 0.00172, respectively, both p>0.05).-VASc score did not significantly increase the predictive ability of the model

    Empathy and affect: what can empathied bodies do?

    While there has been much interest in the apparent benefits of empathy in improving outcomes of medical care, there is continuing concern over the philosophical nature of empathy. We suggest that part of the difficulty in coming to terms with empathy is due to the modernist dichotomies that have structured Western medical discourse, such that doctor and patient, knower and known, cognitive and emotional, subject and object are situated in oppositional terms, with the result that such accounts cannot coherently encompass an emotional doctor, or a patient as knower, or empathy as other than a possession or a trait. This paper explores what, by contrast, a radical critique of the Cartesian world view, in the form of a Deleuzean theoretical framework, would open up in new perspectives on empathy. We extend the framework of emotional geography to ask what happens when people are affected by empathy. We suggest that doctors and patients might be more productively understood as embodied subjects that are configured in their capacities by how they are affected by singular ‘events’ of empathy. We sketch out how the Deleuzean framework would make sense of these contentions and identify some possible implications for medical education and practice. Keywords: Empathy, Medicine, Affect, Philosophy, Subjectivit

    Readers building fictional worlds:visual representations, poetry, and cognition

    This article explores the complex nature of the literature classroom by drawing on the cognitive linguistic framework Text World Theory to examine the teacher’s role as facilitator and mediator of reading. Specifically, the article looks at how one teacher used visual representations as a way of allowing students to engage in a more personal and less teacher-driven transaction with a poem, and to encourage them to reflect on their own roles as active makers of meaning and knowledge in the classroom. The article shows how teachers can be mindful of the various contextual factors that can privilege and legitimise certain kinds of response in the classroom and be wary of external factors and pressures that can promote the idea of preconceived knowledge. The teacher in the case study presented was able to both facilitate the experience of reading poetry in an unmediated way and also develop her students’ metacognition in relation to the reading process itself. The article shows how Text World Theory’s status as a socio-cognitive grammar may be of benefit to teachers in understanding the nature of communicative interaction and literary transaction

    A bicyclic α-iminophosphonate improves cognitive decline in 5xFAD murine model of neurodegeneration

    I2 receptors (I2-IR) are widely distributed in the central nervous system. I2-IR ligands are associated with a neuroprotective effect but, as I2-IR structure remains unknown, the discovery of better and more selective ligands is necessary to understand the pharmacological and molecular implications of I2-IR. Recently, we described a new imidazoline-structure family which showed high affinity and selectivity for I2-IR. In vivo studies in mice indicated a neuroprotective role and revealed beneficial effects in behaviour and cognition with a murine model of neurodegeneration, senescence-accelerated prone mouse (SAMP8). Herein, we report a novel non-imidazoline-structure of bicyclic α-iminophosphonates family with high affinities for I2-IR. In vivo studies in 5X-FAD mice (a transgenic representative model of AD) and SAMP8 mice (a model of neurodegeneration linked to aging) showed an improvement in behaviour and cognition, a reduction of AD hallmarks and of neuroinflammation markers for the mice treated with the lead compound B06. After evaluating several pathways associated with neurodegeneration, we demonstrated that CaN pathway plays a critical role on the neuroprotective effects of I2-IR ligands on SAMP8 mice model. To rule out warnings of the novel family, we calculated DMPK and physicochemical properties for the novel bicyclic α-iminophosphonates. As well, we carried out drug metabolism, safety studies and in vivo pharmacokinetics for lead compound B06. In summary, we present a novel family of I2-IR ligands, its effectiveness in in vivo models and the possible neuroprotective molecular mechanism mediated by them. This highlights that the modulation of I2-IR by bicyclic α-iminophosphonates may open a new therapeutic venue for unmet neurodegenerative conditions
