    Civilization has been analyzed mostly with urbanization which coincides with the usage of stone and later concrete and steel in constructions. Nowadays we have been realized that construction materials used for houses, apartments, roads and pavements surrounding us create local microclimate which influences our living comfort. Local temperature increases due to asphalt roads and concrete pavements have recently been determined and they are remarkably effective in our everyday life. Usage of different types of aggregates in concrete mixtures to cast concrete pavement blocks might effective to decrease air temperature on the pavements. Therefore heat-resistant rocks were used to produce different sized aggregates where different plasters were produced from them to coat standard concrete pavement blocks. Pavement blocks plastered were then put under sun to test their surface temperatures. It was observed that heat-resistive materials used in plaster concretes influence heat distribution in the blocks and surface temperature of the concrete pavement blocks.

    Objectives: To evaluate the rates of pain and mass recurrence of the patients over 40 years old with endometriosis who underwent ovarian cystectomy or uni/bilateral oophorectomy. Material and methods: A retrospective study was conducted with 98 patients undergoing laparoscopic surgery for endometriosis in a tertiary referral center between the time period July 2015 and July 2019. All the patients followed every 3 months and requested to fill the Visual Analogue Scale (VAS) for evaluation of pelvic pain and an ultrasound scan was performed. The inclusion criteria for this study were as follows, patients with ages over 40, with regular menstrual periods, and who denied hysterectomy and any postoperative hormonal medical treatments. Results: When the groups were compared in terms of age, body mass index, cyst diameter, CA-125 serum concentrations, preoperative and after surgical pelvic pain scores, mean follow up periods, postoperative hospital stay. However, each of the mean numbers of gravidity and parity were significantly higher than bilateral salpingo-oophorectomy (BSO) groups compared to the other groups (p = 0.04 and p = 0.03, respectively). The laterality, the recurrence rates, and the type of recurrence did not have a significant effect in the group comparison. Conclusions: The ovarian tissue preserving procedures could be offered for the women over 40 years old suffering from endometriosis with no significant increase in pain symptom or mass recurrence rates considering beneficial effects of estrogen on cardiovascular system, vasomotor symptoms, and bone mineral density

    Objective: Turner syndrome (TS) is a chromosomal disorder caused by complete or partial X chromosome monosomy that manifests various clinical features depending on the karyotype and on the genetic background of affected girls. This study aimed to systematically investigate the key clinical features of TS in relationship to karyotype in a large pediatric Turkish patient population.Methods: Our retrospective study included 842 karyotype-proven TS patients aged 0-18 years who were evaluated in 35 different centers in Turkey in the years 2013-2014.Results: The most common karyotype was 45,X (50.7%), followed by 45,X/46,XX (10.8%), 46,X,i(Xq) (10.1%) and 45,X/46,X,i(Xq) (9.5%). Mean age at diagnosis was 10.2±4.4 years. The most common presenting complaints were short stature and delayed puberty. Among patients diagnosed before age one year, the ratio of karyotype 45,X was significantly higher than that of other karyotype groups. Cardiac defects (bicuspid aortic valve, coarctation of the aorta and aortic stenosis) were the most common congenital anomalies, occurring in 25% of the TS cases. This was followed by urinary system anomalies (horseshoe kidney, double collector duct system and renal rotation) detected in 16.3%. Hashimoto's thyroiditis was found in 11.1% of patients, gastrointestinal abnormalities in 8.9%, ear nose and throat problems in 22.6%, dermatologic problems in 21.8% and osteoporosis in 15.3%. Learning difficulties and/or psychosocial problems were encountered in 39.1%. Insulin resistance and impaired fasting glucose were detected in 3.4% and 2.2%, respectively. Dyslipidemia prevalence was 11.4%.Conclusion: This comprehensive study systematically evaluated the largest group of karyotype-proven TS girls to date. The karyotype distribution, congenital anomaly and comorbidity profile closely parallel that from other countries and support the need for close medical surveillance of these complex patients throughout their lifespa

    Fingu - Is there a relationship between finger counting, finger numbers, and use of Fingu

    Get PDF
    Syfte Syftet med den här uppsatsen är att kontrollera om det finns något samband mellan deltagarnas olika handkonstellationer vid fingerräkning eller fingertal och deras handkonstellationer vid spelandet av datorspelet Fingu. Detta görs för att kunna knyta eller avfärda olika kroppsliga effekter till utvecklandet av den aritmetiska förmågan och spelandet av enkla datorspel i stil med Fingu. Huvudfrågor Finns det likheter mellan fingertal och hur man använder sina fingrar i Fingu? Finns det likheter mellan fingerräkning och hur man använder sina fingrar i Fingu? Är användningen av fingrar i Fingu stabil? Metod och material Tio kvalitativa videoobservationer ligger till grund för uppsatsen, där vi kategoriserat deltagarnas svar och analyserat deras fingerkonstellationer. Resultat Resultatet av den här studien visar att det inte finns några direkta samband mellan spelandet av Fingu och personens fingertal eller fingerräkning. Det visar sig snarare som att fingertal och fingerräkning är en liten del av en större helhet som utvecklar den aritmetiska förmågan. Betydelse för läraryrket Med hjälp av IT kan man på ett sätt möta elever som traditionellt anses vara deras planhalva. Med hjälp av enklare datorspel tror vi att man kan skapa och utveckla ett lärofyllt, utvecklande och lustfyllt sätt att lära sig, exempelvis räkning. Som pedagoger är det av stor vikt att göra undervisningen just sådan och att införa digitala hjälpmedel tror vi är ett steg i den riktningen. Uppsatsen visar att man inom matematikundervisningen inte skall använda sig av Fingu för att utveckla fingertal och fingerräkning. Då vårt resultat strikt visa att det ej finns något samband mellan de och själva spelandet av Fingu

    Background: Accurate and rapid detection of methicillin-resistant Staphylococcus aureus is very important in a clinical laboratory setting to avoid treatment failure. Conventional methods were compared against the gold standard polymerase chain reaction (PCR) technique to determine the best combination of the routine procedures. Methodology: Methicillin resistance was investigated in 416 clinical Staphylococcus aureus isolates by PCR, oxacillin agar screening (OAS), oxacillin disk diffusion (ODD) and cefoxitin disk diffusion (CDD) methods. Results: Two hundred and ten (51%) out of 416 S. aureus strains were found to be mecA-positive by PCR. Sensitivity and specificity of the ODD, CDD and OAS methods were detected as follows: 100% and 89%, 99.50% and 100%, and 99.50% and 100%, respectively . Conclusion: Combining the ODD and CDD methods could be a good choice for detecting methicillin resistance in S. aureus strains where mecA PCR cannot be performed. Key Words : Methicillin-resistant Staphylococcus aureus (MRSA), polymerase chain reaction (PCR), oxacillin disk diffusion, cefoxitin disk diffusion, oxacillin agar screening
