The Influence of Silica Fly Ash and Wood Bottom Ash on Cement Hydration and Durability of Concrete.

This research addresses a notable gap in understanding the synergistic effects of high carbon wood bottom ash (BA) and silica fly ash (FA) on cement hydration and concrete durability by using them as a supplementary material to reduce the amount of cement in concrete and CO emissions during cement production. This study analyses the synergistic effect of FA and BA on cement hydration through X-ray diffraction (XRD), thermal analysis (TG, DTG), scanning electron microscopy (SEM), density, ultrasonic pulse velocity (UPV), compressive strength, and temperature monitoring tests. In addition, it evaluates concrete properties, including compressive strength, UPV, density, water absorption kinetics, porosity parameters, predicted resistance to freezing and thawing cycles, and results of freeze-thawing resistance.

Experimental and theoretical investigation of aortic wall tissue in tensile tests.

Background: Understanding the mechanical properties of aortic tissue is essential for developing numerical computation tools and assessing the risk of aortic aneurysm fractures. Tensile tests using aortic wall specimens allow for the determination of stress and strain depending on the location and direction of the sample.

Objective: The aim of this study was to perform a mechanical tensile test using canine aorta samples and create a numerical model of aortic tissue tension from the processed data.

The Impact of Milled Wood Waste Bottom Ash (WWBA) on the Properties of Conventional Concrete and Cement Hydration.

Wood waste bottom ash (WWBA) is a waste generated in power plants during the burning of forest residues to produce energy and heat. In 2019, approximately 19,800 tons of WWBA was generated only in Lithuania. WWBA is rarely recycled or reused and is mostly landfilled, which is both costly for the industry and unsustainable.

Ring-Shaped Piezoelectric 5-DOF Robot for Angular-Planar Motion.

This paper provides numerical and experimental investigations of a ring-shaped piezoelectric 5-DOF robot that performs planar and angular motions of spherical payload. The robot consists of a piezoelectric ring glued on a special stainless-steel ring with three spikes oriented in the radial direction of the ring. The spherical payload is placed on top of the piezoelectric ring and is moved or rotated when a particular excitation regime is used.

The Effect of Municipal Solid Waste Incineration Ash on the Properties and Durability of Cement Concrete.

The aim of this study is to investigate the effect of municipal solid waste incineration bottom ash from a cogeneration plant on the physical and mechanical properties and durability of cement concrete. Part of the cement in concrete mixtures tested was replaced with 0%, 3%, 6%, 9%, and 12% by weight of municipal solid waste incineration bottom ash. Concrete modified with 6% of bottom ash had a higher density (2323 kg/m), compressive strength at 28 days (36.

Monopolar electrocautery use in minimally invasive urosurgery: Case report of ectopic ureter management in a bitch.

Background: Ureteral ectopy is a congenital anomaly, affecting young dogs, predominantly bitches. The main complication of the disease is urinary incontinence, which leads to low life quality for both animals and their owners. However, only two less invasive surgical management options are reported.

Expression Levels of the Uridine-Cytidine Kinase Like-1 Protein As a Novel Prognostic Factor for Hepatitis C Virus-Associated Hepatocellular Carcinomas.

The expression levels of the two novel oncoproteins uridine-cytidine kinase like-1 (UCKL-1) and mitochondrial ribosomal protein S18-2 (MRPS18-2) were assessed in samples of hepatitis C virus (HCV)-associated hepatocellular carcinoma (HCC) using immunohistochemistry. Tissue microarray (TMA) paraffin blocks were prepared from 42 HCC tumor samples with the corresponding peri-tumor tissues and from 11 tissues of a liver with HCV-induced cirrhosis. We found that the UCKL-1 signal in the liver tissues of the peri-tumor zone in the HCC samples was stronger than that in cirrhosis (50 ± 49.

[Professional socialization of nurses ensuring practice activity].

Unlabelled: The aim of this study was to evaluate professional socialization of nurses and its association with assurance of practice activity.

Material And Methods: The study was carried out in randomly selected Lithuanian health care institutions from January to June 2007. A total of 1300 nurses, enrolled in the study, were divided into three groups according to the position held by participants: general practice nurses, 77.

Use of the HoNOSCA scale in the teamwork of inpatient child psychiatry unit.

The aims of this study were to introduce the Health of the Nation Outcome Scales for Children and Adolescents (HoNOSCA) into the clinical practice, to assess the possibilities to use HoNOSCA in the interdisciplinary teamwork of child psychiatric inpatient unit and to analyse differences in evaluation of HoNOSCA among team members scoring different diagnostic groups of children. HoNOSCA was translated into Lithuanian and team members were trained to use the scale. Inter-rater reliabilities between various pairs of specialists and between all members of the team were calculated using intraclass correlations calculated for each item of the scale and total score.
