    V diplomski nalogi je predstavljena izdelava računske energetske izkaznice s poudarkom na priporočilih za energetsko sanacijo dvostanovanjske stavbe, locirane v Medvodah. Stavba je bila zgrajena leta 1985. V tem obdobju se je začela uporabljati toplotna izolacija, saj so se že pojavljala vprašanja o energetski učinkovitosti stavb. Energetska izkaznica stavb je potrebna pri prodaji in najemu stavbe, če je obdobje najema daljše od enega leta. Obvezna je tudi pri novogradnji kot del projekta izvedenih del. V uvodnem delu sem predstavil veljavno zakonodajo, ki ureja področje učinkovite rabe energije v stavbah. Potem sem s pomočjo programa TEDI in TOST izdelal računsko energetsko izkaznico za obravnavani objekt v obstoječem stanju, nato pa sem se osredotočil na učinkovitost posameznega ukrepa energetske sanacije. Pri vsakem ukrepu sem komentiral dobljene rezultate in se odločil o smiselnosti njegove izvedbe v odvisnosti od tehnične zahtevnosti in posledičnega prihranka energije. Pri obravnavani stavbi se največ energije, potrebne za ogrevanje z menjavo transparentnega dela in mehanskim prezračevanjem, prihrani z vračanjem toplote odpadnega zraka, in sicer blizu 50 %. Z izborom vseh ukrepov, za katere menim, da so smiselni, pa se prihrani preko 80 % potrebne letne toplote za ogrevanje stavbe. Tudi koeficient specifičnih transmisijskih izgub se zmanjša za 60 %. Poveča pa se potreba po hlajenju, kar je tipična stranska škoda zelo dobro toplotno izoliranih stavb. V zaključnem delu so predstavljene ugotovitve, nastale tekom diplomske naloge.In the undergraduate thesis, the production of the calculated energy performance certificate for the specific building is undertaken. This is done with the emphasis on recommendations for energy renovation of the duplex residential building, which is located in Medvode, Slovenia and was built in 1985. When the building was constructed, energy efficiency was already gaining importance. Consequently many buildings constructed in this period were moderately thermally insulated. An energy performance certificate is legally required when a building is offered for purchase and when it is leased for a period longer than one year. Furthermore the certificate is mandatory for newly built properties, as a basic requirement for the project plan. The thesis initially examines the current legislation, which regulates the area of energy efficiency in buildings. Next the energy performance for the considered building will be produced. This will be done with TEDI and TOST computer software. After that, individual technical measures will be analysed. The viability of these measures will be assessed in consideration of technical complexity and estimated energy savings potential. For the considered building, the greatest energy savings can be realised with exterior joinery renovation and installation of heat recovery ventilation. The implementation of booth measures accounts for about 50% of energy savings. With the comprehensive renovation, more than 80% of the annual heat required for the building would be preserved. In this case the specific heat transfer coefficient would decrease by about 60 %. On the contrary the requirements for cooling would increase, which is the common downside of a well-insulated building

    Introduction: Leucocyte telomere length (LTL) has been described as a marker of biological age, endothelial dysfunction and atherosclerosis. The association between LTL and clinical characteristics of Asian patients, and their outcomes following acute myocardial infarction (AMI) have been inconclusive. Objective: To investigate the relationship between LTL and developing AMI, the association of LTL with inpatient and 30-day mortality, and the comparison to LTL with established AMI risk scores in predicting these outcomes. Methodology: 100 patients aged 30-70 years admitted with an AMI to a tertiary referral center between May-Oct 2017 were enrolled; these were matched with 100 non-AMI ('healthy') controls for gender and age (+/- 1 year). Clinical data was obtained prospectively; inpatient and 30-day outcomes documented. LTL was reflected by a well described variable called a tis ratio (TSR). The TSR was measured at enrolment using a quantitative PCR-based methods (qPCR) and results blinded to the clinician

    This is the author accepted manuscript. The final version is available from Nature Publishing Group via http://dx.doi.org/10.1038/ng.3448Advanced age-related macular degeneration (AMD) is the leading cause of blindness in the elderly, with limited therapeutic options. Here we report on a study of >12 million variants, including 163,714 directly genotyped, mostly rare, protein-altering variants. Analyzing 16,144 patients and 17,832 controls, we identify 52 independently associated common and rare variants (P < 5 × 10(-8)) distributed across 34 loci. Although wet and dry AMD subtypes exhibit predominantly shared genetics, we identify the first genetic association signal specific to wet AMD, near MMP9 (difference P value = 4.1 × 10(-10)). Very rare coding variants (frequency <0.1%) in CFH, CFI and TIMP3 suggest causal roles for these genes, as does a splice variant in SLC16A8. Our results support the hypothesis that rare coding variants can pinpoint causal genes within known genetic loci and illustrate that applying the approach systematically to detect new loci requires extremely large sample sizes.We thank all participants of all the studies included for enabling this research by their participation in these studies.

    Background: Short-term treatment for people with type 2 diabetes using a low dose of the selective endothelin A receptor antagonist atrasentan reduces albuminuria without causing significant sodium retention. We report the long-term effects of treatment with atrasentan on major renal outcomes. Methods: We did this double-blind, randomised, placebo-controlled trial at 689 sites in 41 countries. We enrolled adults aged 18–85 years with type 2 diabetes, estimated glomerular filtration rate (eGFR)25–75 mL/min per 1·73 m 2 of body surface area, and a urine albumin-to-creatinine ratio (UACR)of 300–5000 mg/g who had received maximum labelled or tolerated renin–angiotensin system inhibition for at least 4 weeks. Participants were given atrasentan 0·75 mg orally daily during an enrichment period before random group assignment. Those with a UACR decrease of at least 30% with no substantial fluid retention during the enrichment period (responders)were included in the double-blind treatment period. Responders were randomly assigned to receive either atrasentan 0·75 mg orally daily or placebo. All patients and investigators were masked to treatment assignment. The primary endpoint was a composite of doubling of serum creatinine (sustained for ≥30 days)or end-stage kidney disease (eGFR <15 mL/min per 1·73 m 2 sustained for ≥90 days, chronic dialysis for ≥90 days, kidney transplantation, or death from kidney failure)in the intention-to-treat population of all responders. Safety was assessed in all patients who received at least one dose of their assigned study treatment. The study is registered with ClinicalTrials.gov, number NCT01858532. Findings: Between May 17, 2013, and July 13, 2017, 11 087 patients were screened; 5117 entered the enrichment period, and 4711 completed the enrichment period. Of these, 2648 patients were responders and were randomly assigned to the atrasentan group (n=1325)or placebo group (n=1323). Median follow-up was 2·2 years (IQR 1·4–2·9). 79 (6·0%)of 1325 patients in the atrasentan group and 105 (7·9%)of 1323 in the placebo group had a primary composite renal endpoint event (hazard ratio [HR]0·65 [95% CI 0·49–0·88]; p=0·0047). Fluid retention and anaemia adverse events, which have been previously attributed to endothelin receptor antagonists, were more frequent in the atrasentan group than in the placebo group. Hospital admission for heart failure occurred in 47 (3·5%)of 1325 patients in the atrasentan group and 34 (2·6%)of 1323 patients in the placebo group (HR 1·33 [95% CI 0·85–2·07]; p=0·208). 58 (4·4%)patients in the atrasentan group and 52 (3·9%)in the placebo group died (HR 1·09 [95% CI 0·75–1·59]; p=0·65). Interpretation: Atrasentan reduced the risk of renal events in patients with diabetes and chronic kidney disease who were selected to optimise efficacy and safety. These data support a potential role for selective endothelin receptor antagonists in protecting renal function in patients with type 2 diabetes at high risk of developing end-stage kidney disease.

    Tears evoke the intention to offer social support: A systematic investigation of the interpersonal effects of emotional crying across 41 countries

    Get PDF
    Tearful crying is a ubiquitous and likely uniquely human phenomenon. Scholars have argued that emotional tears serve an attachment function: Tears are thought to act as a social glue by evoking social support intentions. Initial experimental studies supported this proposition across several methodologies, but these were conducted almost exclusively on participants from North America and Europe, resulting in limited generalizability. This project examined the tears-social support intentions effect and possible mediating and moderating variables in a fully pre-registered study across 7007 participants (24,886 ratings) and 41 countries spanning all populated continents. Participants were presented with four pictures out of 100 possible targets with or without digitally-added tears. We confirmed the main prediction that seeing a tearful individual elicits the intention to support, d = 0.49 [0.43, 0.55]. Our data suggest that this effect could be mediated by perceiving the crying target as warmer and more helpless, feeling more connected, as well as feeling more empathic concern for the crier, but not by an increase in personal distress of the observer. The effect was moderated by the situational valence, identifying the target as part of one's group, and trait empathic concern. A neutral situation, high trait empathic concern, and low identification increased the effect. We observed high heterogeneity across countries that was, via split-half validation, best explained by country-level GDP per capita and subjective well-being with stronger effects for higher-scoring countries. These findings suggest that tears can function as social glue, providing one possible explanation why emotional crying persists into adulthood.</p

    A multi-country test of brief reappraisal interventions on emotions during the COVID-19 pandemic.

    The COVID-19 pandemic has increased negative emotions and decreased positive emotions globally. Left unchecked, these emotional changes might have a wide array of adverse impacts. To reduce negative emotions and increase positive emotions, we tested the effectiveness of reappraisal, an emotion-regulation strategy that modifies how one thinks about a situation. Participants from 87 countries and regions (n = 21,644) were randomly assigned to one of two brief reappraisal interventions (reconstrual or repurposing) or one of two control conditions (active or passive). Results revealed that both reappraisal interventions (vesus both control conditions) consistently reduced negative emotions and increased positive emotions across different measures. Reconstrual and repurposing interventions had similar effects. Importantly, planned exploratory analyses indicated that reappraisal interventions did not reduce intentions to practice preventive health behaviours. The findings demonstrate the viability of creating scalable, low-cost interventions for use around the world
