Diagnostic tools for female urethral diverticulum: Current perspectives

2019

Although once considered quite a rare condition in the past, female urethral diverticulum (UD) would now appear to have a higher frequency, perhaps due to greater attention from physicians. To date, there is no agreement on which is the best method for diagnosis of female UD. Traditionally, the approach was based on quite invasive techniques, such as voiding cystourethrography, and double-balloon urethrography, with satisfactory results but relevant limitations. More recent high-resolution imaging techniques, such as 2D-3D ultrasonography (US) and magnetic resonance imaging (MRI) have also been applied in the study of the abnormalities of the female urethra. US had the advantage of the outp…

Integrated marketing communication as a business management tool in the context of sustainable development

2018

AbstractThe problem of nowadays is that consumers lack information on food products, their composition and quality, nutritional value, packaging, its impact on the human health and environment, reuse and recycling possibilities, etc. Integrated marketing communications (IMC) as a business management tool may not only draw the consumers’ attention and incite a purchase, but also provide information and serve as a facilitator of consumers’ knowledge and competence on products, their nutritional value, use and utilisation. The goal of the research is to assess the impact of IMC for sustainability upon demand at Latvian food retail chains and the impact of the use of IMC for sustainability upon…

INTEGRATED MARKETING COMMUNICATIONS IN SUSTAINABLE BUSINESS

2018

Business sustainability hinges on authorities’ action, cooperation and willingness to protect nature and natural resources, but they also have to meet the economic needs and cultivate the economic opportunities, whilst also satisfying the social needs and building a fair relationship among the different social groups. One of the ways to develop a sustainable business is integrated marketing communications. When using integrated marketing communications, businesses – notably food producers and retailers – need to focus on the education of consumers, the ecological performance and impact of products on the environment and human health, thus contributing to a sustainable development of Latvia’…

Environmental modelling of aluminium based components manufacturing routes: Additive manufacturing versus machining versus forming

2018

Abstract Additive Manufacturing represents, by now, a viable alternative for metal-based components production. Therefore the designer, often, has to select among three options at process design stage: subtractive, mass conserving, and additive approaches. The selection of a given process, besides affecting the manufacturing step impact, influences significantly the impact related to the material production step. If the process enables a part weight reduction (as the Additive Manufacturing approaches do) even the use phase is affected by the manufacturing approach selection. The present research provides a comprehensive environmental manufacturing approaches comparison for components made o…

Focal DNA Copy Number Changes in Neuroblastoma Target MYCN Regulated Genes

2013

Neuroblastoma is an embryonic tumor arising from immature sympathetic nervous system cells. Recurrent genomic alterations include MYCN and ALK amplification as well as recurrent patterns of gains and losses of whole or large partial chromosome segments. A recent whole genome sequencing effort yielded no frequently recurring mutations in genes other than those affecting ALK. However, the study further stresses the importance of DNA copy number alterations in this disease, in particular for genes implicated in neuritogenesis. Here we provide additional evidence for the importance of focal DNA copy number gains and losses, which are predominantly observed in MYCN amplified tumors. A focal 5 kb…

The future of assessment in Higher Education

2020

The pending challenge of assessment in higher education, although also at other educational levels, continues to be its effective link with student learning. Students' strategic learning could and should be achieved by the assessment. This paper arises from the attempt to answer the question about what would be the future of assessment in higher education and it is presented under the form of a collaborative text that was elaborated by all the authors who sign it. This contribution offers a joint reflection by various authors from different contexts and regions on three essential aspects. First, the need for reflection and a change in assessment based on current trends that are demonstratin…

Subsistence strategies throughout the African Middle Pleistocene: Faunal evidence for behavioral change and continuity across the Earlier to Middle S…

2018

Abstract The African Middle Pleistocene (781–126 ka) is a key period for human evolution, witnessing both the origin of the modern human lineage and the lithic turnover from Earlier Stone Age (ESA) Acheulean bifacial tools to Middle Stone Age (MSA) prepared core and point technologies. This ESA/MSA transition is interpreted as representing changing landscape use with greater foraging distances and more active hunting strategies. So far, these behavioral inferences are mainly based on the extensive stone tool record, with only a minor role for site-based and regional faunal studies. To provide additional insights into these behavioral changes, this paper details a pan-African metastudy of 63…

Improving the Performance of Steel Machining Processes through Cutting by Vibration Control

2021

Machining processes through cutting are accompanied by dynamic phenomena that influence the quality of the processed surfaces. Thus, this research aimed to design, make, and use a tool with optimal functional geometry, which allowed a reduction of the dynamic phenomena that occur in the cutting process. In order to carry out the research, the process of cutting by front turning with transversal advance was taken into account. Additionally, semi-finished products with a diameter of Ø = 150 mm made of C45 steel were chosen for processing (1.0503). The manufacturing processes were performed with the help of two tools: a cutting tool, the classic construction version, and another that was the i…

Unintended Effects of Energy Efficiency Policy: Lessons Learned in the Residential Sector

2021

The European Union has set an ambitious goal to tackle climate change, and energy efficiency in the residential sector is among the measures required to close the gap between targeted and actual greenhouse gas emissions. While different policy tools have been applied, the diffusion rate of these measures remains low. A system dynamics simulation model of the residential sector was developed to assess the advantages and drawbacks of energy efficiency policy in the multi-family building sector based on experience accumulated over the last twelve years in Latvia. The model was validated in expert group model building sessions and with historical trends. Simulating the model, a hypothesis was t…
