A REVIEW OF COLOR MEASURMENTS IN THE TEXTILE INDUSTRY
2016
Color is an important factor in the evaluation of aesthetic appearance and functionality of many products, but especially of textile industry ones. In textiles production process, color can be assessed in different stages: the selection of raw materials, the incoming item tests, the preparation of dyeing ingredients, the crocking resistance testing, the color fastness and in all stages, the quality control. Color evaluation can be done visually or using specialized test instruments such as colorimeters or spectrometers, therefore a high accuracy of measurements must be achieved. Standards describe different procedures and testing techniques depending on the product type and the quality leve…

Gaining or losing PhDs: What are the effects on firms' linkages with universities?
2023
PhD graduates can help companies transfer knowledge from universities to firms. Scholars have analysed the determinants of PhD recruitment by firms and its effects on their innovation activities. However, little is known about what happens when a firm loses employees with PhDs. The aim of this paper is to compare the effects on the relationships of firms with universities when these firms lose PhDs versus when they hire PhDs to work in R&D. These effects may be symmetrical or non-symmetrical depending on the abilities of firms to retain the connections and knowledge acquired by hiring PhDs. We consider four types of relationships: collaboration with universities, universities as a source of…
Centrālo venozo katetru aprūpes protokola izstrāde un ieviešana stacionārā
2015
Maģistra darba „Centrālo venozo katetru aprūpes protokola izstrāde un ieviešana stacionārā” mērķis ir izanalizēt literatūru par centrālajiem venozajiem katetriem, ar tiem saistītajām infekcijām un centrālo venozo katetru aprūpes protokolus citur pasaulē. Praktiskajā daļā apzināta un izvērtēta līdzšinējā aprūpes prakse, izstrādāts stacionāram piemērots centrālo venozo katetru aprūpes protokols un novērtēti sākotnējie ieguvumi. Pētījuma jautājumi ir: Kādas ir nepilnības centrālo venozo katetru aprūpes līdzšinējā praksē? Kādi ir ieguvumi, lietojot centrālo venozo katetru aprūpes protokolu? Praktiskajā daļā izmantota kvantitatīvā un kvalitatīvā pētniecības metode. Maģistra darbs sastāv no 9 nod…
Data from: Ocean acidification affects fish spawning but not paternity at CO2 seeps
2016
Fish exhibit impaired sensory function and altered behaviour at levels of ocean acidification expected to occur owing to anthropogenic carbon dioxide emissions during this century. We provide the first evidence of the effects of ocean acidification on reproductive behaviour of fish in the wild. Satellite and sneaker male ocellated wrasse (Symphodus ocellatus) compete to fertilize eggs guarded by dominant nesting males. Key mating behaviours such as dominant male courtship and nest defence did not differ between sites with ambient versus elevated CO2 concentrations. Dominant males did, however, experience significantly lower rates of pair spawning at elevated CO2 levels. Despite the higher r…

Inclusive Search for Standard Model Higgs Boson Production in the WW Decay Channel using the CDF II Detector
2010
We present a search for standard model (SM) Higgs boson production using p (p) over bar collision data at root s = 1. 96 TeV, collected with the CDF II detector and corresponding to an integrated luminosity of 4. 8 fb(-1). We search for Higgs bosons produced in all processes with a significant production rate and decaying to two W bosons. We find no evidence for SM Higgs boson production and place upper limits at the 95% confidence level on the SM production cross section (sigma(H)) for values of the Higgs boson mass (m(H)) in the range from 110 to 200 GeV. These limits are the most stringent for m(H) > 130 GeV and are 1.29 above the predicted value of sigma(H) for m(H) 165 GeV.

Dual compensation control-system for offshore logistic equipment
2012
In offshore applications and moreover in transports from ship-to-ship, the needs of highly sophisticated motion compensation solution are increasing. They consist of sensors, actuators and control units. To design the best mechatronic solution, it is necessary modeling the mechanical system in order to identify the transfer function and the dynamic behaviour of the system. Currently Active Heave Compensation system are widely used in order to compensate for heave vessel motion. between a vessel moving under sea state and a fixed base or viceversa. Several research project are ongoing in order to develop solution able to compensate undesired movements also in ship to ship offloading operatio…
