Strengths and Failure Characteristics of Self-Compacting Concrete Containing Recycled Waste Glass Aggregate

The effects of different proportions of green-colored waste glass (WG) cullet on the mechanical and fracture properties of self-compacting concrete (SCC) were experimentally investigated. Waste bottles were collected, washed, crushed, and sieved to prepare the cullet used in this study. Cullet was incorporated at different percentages (0%, 20%, 40%, 60%, 80%, and 100% by weight) instead of natural fine aggregate (NFA) and/or natural coarse aggregate (NCA). Three SCC series were designed with a constant slump flow of 700±30 mm, total binder content of 570 kg/m3 and at water-to-binder (w/b) ratio of 0.35. Moreover, fly ash (FA) was used in concrete mixtures at 20% of total binder content. Mechanical aspects such as compressive, splitting tensile, and net flexural strengths and modulus of elasticity of SCC were investigated and experimentally computed at 28 days of age. Moreover, failure characteristics of the concretes were also monitored via three-point bending test on the notched beams. The findings revealed that the mechanical properties as well as fracture parameters were adversely influenced by incorporating of WG cullet. However, highest reduction of compressive strength did not exceed 43% recorded at 100% WG replacement level. Concretes containing WG showed less brittle behavior than reference concrete at any content

Have COVID-19 pandemic restrictions impacted the functioning of the hematology clinic?

Amaç: Çalışmamızın amacı, kısıtlamaların uygulandığı COVID-19 pandemi sürecinde hematoloji klinik işleyişinin değerlendirilmesidir. Hastalar ve Yöntem: Pandeminin ilk döneminde sokağa çıkma kısıtlamalarının uygulandığı 13.03.2020-15.05.2020 ile bu tarih aralığına karşılık gelen 2019 döneminde Necmettin Erbakan Üniversitesi Meram Tıp Fakültesi ve İstanbul Medipol Üniversitesi Tıp Fakültesi Erişkin Hematoloji kliniklerine yatışı yapılan hastalar retrospektif olarak değerlendirildi. Bulgular: Her iki dönemde de yatan hasta sayısı 266 idi. 65 yaş üstü hasta oranı anlamlı olmamakla birlikte 2020’de daha düşük saptandı (%33.1’e kaşın %40.6, p= 0.72). Pandemi döneminde 2019’a göre tanısal amaçlı yatışı yapılan hasta sayısı anlamlı olarak yüksek (OR: 2,1, %95 GA: 1.35-3.26, p< 0.001); herhangi bir enfeksiyon nedeniyle yatış oranı ise düşük (OR: 0,44, %95 GA: 0.27-0.71, p< 0.001) bulundu. Tanısal amaçlı yatış yapılan hastalarda 2020 yılında hem erkek hasta oranı yüksek (OR: 0.4, %95 GA: 0.18-0.92, p= 0.031) hem de yatış süresi daha uzun (medyan 7’ye 14 gün, p= 0.007) bulundu. Kemoterapi, destek ve mobilizasyon amaçlı yatışlar arasında fark saptanmadı. Replasman ihtiyacı nedeniyle yatışı yapılan hasta oranı yine pandemic döneminde yüksek iken (OR: 4.7, %95 GA: 1.7-12.6, p< 0.001), tüm hastalar değerlendirildiğinde kan ürünü kullanımı sıklığı iki yıl arasında farklı değildi. Sonuç: Çalışmamız, kısıtlamalar sürecinde hematoloji hasta yönetiminin önemini ve işlevselliğinin değişmediğini vurgulamaktadır.Objective: The aim of our study is to assess the clinical functioning of hematology during the COVID-19 pandemic when lockdown restrictions are enforced. Patients and Methods: Patients who were admitted to Necmettin Erbakan University Meram Medical Faculty and Istanbul Medipol University Medical Faculty Adult Hematology clinics between March 13, 2020, and May 15, 2020, when lockdown restrictions were enforced in the first phase of the pandemic were evaluated retrospectively by comparing them with those who were admitted to same clinics between March 13, 2019, and May 15, 2019. Results: The number of inpatients during both periods was 266. It was determined that during the period of the pandemic, the number of patients hospitalized for diagnostic purposes was significantly higher compared to 2019 (OR: 2.1, 95% CI: 1.35-3.26, p< 0.001), whereas the rate of hospitalization due to any infection was significantly lower (OR: 0.44, 95% CI: 0.27-0.71, p<0.001). Of the patients who were hospitalized for diagnostic purposes in 2020, both the rate of male patients was higher (OR: 0.4, 95% CI: 0.18-0.92, p= 0.031) and the duration of hospitalization was longer (7 vs. 14 days; p= 0.007) found. While the rate of patients hospitalized due to the need for replacement was also higher during the period of pandemic (OR: 4.7, 95% CI; 1.7-12.6, p< 0.001), when all patients were assessed, the frequency of blood product use was not different between two years. Conclusion: Our study highlights the cruciality and functionality of hematology patient management during the period of lockdown restrictions

Design and implementation of irrigation prototype system based GSM

Smart farming is one of the keys for future agriculture because it is a management to use modern technology for increasing the quality and quantity of the agriculture. And because of the planet quality depend on the amount of water and the characteristics of soil, it is necessary to study the soil using the soil moisture sensor to investigate whether the soil is dry or wet, also to consider the challenges that could be faced in agricultural environment by maintain the soil and the planets irrigated without extra usage of water. In this paper, a prototype irrigation system uses Arduino Uno microcontroller which is programmed in C++ language to sense the degree of moisture by using soil moisture sensor. According to moisture sensor readings, when the moisture sensor above 1000, Arduino triggers to supply the water by using 5V mini water pump and stop when the soil moisture sensor reading reaches below 400. GSM technology enables the user to be notified in any changes happening in agricultural area by sending SMS (Short Message Service). Whenever the soil become wet or dry and the mini water pump switched on or off, a message delivered to user’s cellular phone indicating the condition of the soil and the action of water pump. In that capacity, this prototype will reduce the time for the user by monitoring remotely without going to his land, and also to reduce the usage of water by allow the water pump to flow the water for limited time until the moisture degree raise again

Failure characteristics of self-compacting concretes made with recycled aggregates

WOS: 000363069800036This study addresses the properties of self-compacting concretes (SCCs) produced with recycled coarse aggregates (RCAs) and/or recycled fine aggregates (RFAs) compared to SCCs with natural aggregates (NAs). The SCC mixtures were designed with a constant slump flow of 680 +/- 30 mm and two water/binder (w/b) ratios of 0.3 and 0.43. Silica fume (SF) was also used at two replacement levels of 0% and 10%. Hardened properties of the SCCs were evaluated in terms of compressive strength, splitting tensile strength, static modulus of elasticity, and net flexural strength after 56 days of water curing. Failure mechanism of the concretes was also monitored via three-point bending test on the notched beams. The results indicated that failure occurred throughout the recycled aggregates (RAs) which in-turn decreased the mechanical properties of SCCs. However, SCCs with both fine and coarse RAs (RCAs + RFAs) had relatively worse performance than those with only RCAs or RFAs such that the reduction in strength was about 30% as compared to the corresponding reference mixes. Moreover, incorporating SF and decreasing w/b ratio improved the mechanical properties of SCCs. (C) 2015 Elsevier Ltd. All rights reserved

Rare malignancies of the bladder: Case series and review of the literature

Patients who operated the diagnosis with bladder cancer were evaluated retrospectively. Patients with a rare pathology was determined. Rare tumors of the bladder was investigated by examining the literature. Our clinic diagnosis and treatment algorithms were compared with the literature. A rare tumor of the bladder cannot be recognized by most urologists and pathologists. Therefore, it can cause difficulties during diagnosis and treatment

Durability and Shrinkage Characteristics of Self-Compacting Concretes Containing Recycled Coarse and/or Fine Aggregates

This paper addresses durability and shrinkage performance of the self-compacting concretes (SCCs) in which natural coarse aggregate (NCA) and/or natural fine aggregate (NFA) were replaced by recycled coarse aggregate (RCA) and/or recycled fine aggregate (RFA), respectively. A total of 16 SCCs were produced and classified into four series, each of which included four mixes designed with two water to binder (w/b) ratios of 0.3 and 0.43 and two silica fume replacement levels of 0 and 10%. Durability properties of SCCs were tested for rapid chloride penetration, water sorptivity, gas permeability, and water permeability at 56 days. Also, drying shrinkage accompanied by the water loss and restrained shrinkage of SCCs were monitored over 56 days of drying period. Test results revealed that incorporating recycled coarse and/or fine aggregates aggravated the durability properties of SCCs tested in this study. The drying shrinkage and restrained shrinkage cracking of recycled aggregate (RA) concretes had significantly poorer performance than natural aggregate (NA) concretes. The time of cracking greatly prolonged as the RAs were used along with the increase in water/binder ratio

A Rare Case Mimicking Ureteral Stone or Tumor: Intraureteral Organized Debris

Intraluminal ureteral debris, hematomas or foreign body, which may mimic ureteral stones and tumors, are extremely rare cases. While renal colic and macroscopic hematuria are generally the causes for presenting, establishing the correct diagnosis with radiologic imaging is not always possible. In particular, urinary tract interventions such as previous intraabdominal operations, extracorporeal shock wave lithotripsy or percutaneous nephrolithotomy or usage of anticoagulant, the presence of ureteral hematoma, debris or foreign bodies in patient records should be considered in the definitive diagnosis. In this study we presented a 54-year-old female patient, who had right flank pain and macroscopic hematuria complaint for a month and had, grade 3 pelvicalyceal dilatation on the right side, filling defect in the right ureterovesical junction according to their intravenous pyelography. In our patient, we initially thought the cause as non-opaque ureteral stone or ureteral tumors, however we understood that the correct diagnosis was an organized intraureteral debris in 3 cm diameter after the diagnostic ureterorenoscopy
