The aim of the paper is to compare the employers' and employees' insights on human capital quality defining and human capital development at organisational level, based on a survey carried out in the county of Satu Mare, Romania. Our findings show that as human capital buyers, employers understand by human capital quality professional background and skills, professional behaviour and efficiency and productivity for the organisation. As human capital sellers, for employees human capital quality means health and the ability to learn and to be suitable to the job requirements. Regarding the opportunities to develop the organisational human capital, the views of employers and employees are very different when the level of discussion is international (macro-level). Employees consider that the international environment has a greater impact on human capital development in their organisation as the employers.
The contact resistance of two interlacing electro-conductive yarns embedded in a hybrid woven fabric will constitute a problem for electro-conductive textiles under certain circumstances. A high contact resistance can induce hotspots, while a variable contact resistance may cause malfunctioning of the components that are interconnected by the electro-conductive yarns. Moreover, the contact robustness should be preserved over time and various treatments such as washing or abrading should not alter the functioning of the electro-conductive textiles. The electrical resistance developed in the contact point of two interlacing electro-conductive yarns is the result of various factors. The influence of diameter of the electro-conductive stainless steel yarns, the weave pattern, the weft density, and the abrasion on the contact resistance was investigated. Hybrid polyester fabrics were produced according to the design of experiments (DoE) and statistical models were found that describe the variation of the contact resistance with the selected input parameters. It was concluded that the diameter of the stainless steel warp and weft yarns has a statistically significant influence on the contact resistance regardless of the weave. Weft density had a significant influence on the contact resistance but only in case of the twill fabrics. Abrasion led to an increase in contact resistance regardless of the weave pattern and the type of stainless steel yarn that was used. Finally, a combination of parameters that leads to plain and twill fabrics with low contact resistance and robust contacts is recommended.
Flooding remains the most widely distributed natural hazard in Europe, leading to significant economic and social impact. Earth observation data is presently capable of making fundamental contributions towards reducing the detrimental effects of extreme floods. Technological advance makes development of online services able to process high volumes of satellite data without the need of dedicated desktop software licenses possible. The main objective of the case study is to present and evaluate a methodology for mapping of flooded areas based on MODIS satellite images derived indices and using state-of-the-art geospatial web services. The methodology and the developed platform were tested with data for the historical flood event that affected the Danube floodplain in 2006 in Romania. The results proved that, despite the relative coarse resolution, MODIS data is very useful for mapping the development flooded area in large plain floods. Moreover it was shown, that the possibility to adapt and combine the existing global algorithms for flood detection to fit the local conditions is extremely important to obtain accurate results.
This paper presents innovative usage of knowledge system into Failure Mode and Effects Analysis (FMEA) process using the ontology to represent the knowledge. Knowledge system is built to serve multi-projects work that nowadays are in place in any manufacturing or services provider, and knowledge must be retained and reused at the company level and not only at project level. The system is following the FMEA methodology and the validation of the concept is compliant with the automotive industry standards published by Automotive Industry Action Group, and not only. Collaboration is assured trough web-based GUI that supports multiple users access at any time
Electro-conductive (EC) yarns can be woven into a hybrid fabric to enable electrical current to flow through the fabric from one component A to another component B. These hybrid fabrics form the bases of woven e-textiles. However, at the crossing point of an EC yarn in warp and in weft direction, there is a contact resistance and thus generation of heat may occur in this area. Both phenomena are inseparable: if the contact resistance in the EC contact increases, the generated heat will increase as well. Predicting this electrical and thermal behavior of EC contacts in hybrid woven fabrics with stainless steel yarns is possible with a mathematical model based on the behavior of a metal oxide varistor (MOV). This paper will discuss in detail how this can be achieved.
Fabric Touch Tester (FTT) is a relatively new device from SDL Atlas to determine touch properties of fabrics. It simultaneously measures 13 touch-related fabric physical properties in four modules that include bending and thickness measurements. This study aims to comparatively analyze the thickness and bending measurements made by the FTT and the common standard methods used in the textile industry. The results obtained with the FTT for 11 different fabrics were compared with that of standard methods. Despite the different measurement principle, a good correlation was found between the two methods used for the assessment of thickness and bending. As FTT is a new tool for textile comfort measurement and no standard yet exists, these findings are essential to determine the reliability of the measurements and how they relate to the well-established standard methods.
The research was conducted on a number of 24 sexually mature male rabbits of common breed, divided into two numerically equal groups. The subjects from the experimental group were given 20 mg/kg nandrolone decanoate, intramuscularly, twice a week for four consecutive weeks. The control group did not receive any treatment. At the end of the experiment the testes were harvested through bilateral orchiectomy and processed for carrying out histopathological investigations. Testicular fragments were fixated in Stieve’s mixture for 24 hours, dehydrated with alcohol, clarified with butyl alcohol and included in paraffin. Serial sections of 5 μ thickness were stained by Masson's trichrome method modified by Goldner. The testes taken from the control animals showed no detectable changes in optical microscopy. In the case of the animals belonging to experimental lots, there were alterations revealed evidenced by vacuolar dystrophy in the spermatocytes and spermatids, apoptosis, the edema of sperm head, spermatids syncytialization and cell necrosis followed by the disintegration of the seminal cell line with the formation of cellular debris in the seminiferous tubules lumen. These changes have affected part of the seminal cell line from the adluminal compartment (primary and secondary spermatocytes, spermatids and spermatozoids), but not those from the basal compartment (type A1 and B spermatogonia), which proved to be resistant in the conditions of 30 days exposure, at a dose of 20 mg/kg. In this context spermatogenesis is affected only for the period of drug action, but the risk of nandrolone decanoate transmission to humans through animal origin food consumption remains, with negative consequences on the spermatogenesis.
The fiscal analysis is an important research topic, aiming at identifying/creating fair fiscal systems, which can respond to requests coming from both the state (which needs revenue to finance various public projects) and from taxpayers. The economic agents, but also the taxpayers will always want a reduction of the taxes, and the public decider aims to increase the revenues attracted to the budget through (higher) taxes. An optimal tax system could be characterized by taxes that produce minimal effects of distorting the behavior of taxpayers, as well as a positive impact on the development of society.
