Individuālo aizsardzības līdzekļu izvēles kritēriji un to nozīme darba vides risku mazināšanā UPB holdinga iekļautajos uzņēmumos
2017
Kvalifikācijas darba tēma “Individuālo aizsardzības līdzekļu izvēles kritēriji SIA „Stiklu centrs”, darba autors, Emīls Beitiņš, darba vadītājs pasniedzējs Mg.da., Daina Pužule. Tēma ir aktuāla, jo uzņēmumā 2016. un 2017.gadā darbinieki ir guvuši traumas, lietojot individuālos aizsardzības līdzekļus, iespējamie riski nesamazinās. Līdz ar to tiek meklēti atbilstoši aizsardzības līdzekļi, kuri palīdzētu novērst turpmākos nelaimes gadījumus. Darba mērķis: izpētīt un atrast piemērotāko individuālo aizsardzības līdzekļu izvēles kritērijus, kā arī izpētīt individuālo aizsardzības līdzekļu veidus: Darba uzdevumi: • izpētīt ražošanas nodaļu uzņēmumā; • apkopot normatīvos aktus un dokumentus, kas re…
Le leverage buy-out
1998
Les acquisitions de sociétés à l'aide d'un holding endetté, ou leverage buy-outs (LBO), ont connu un essor remarquable aux Etats-Unis (depuis les années 1970) et en Europe (à partir des années 1980). Ces opérations permettent aux acquéreurs (capital-investisseurs, personnes physiques...), de conserver ou d'acquérir le contrôle de la société visée tout en minimisant leurs apports en fonds propres. La première partie de cet article est consacrée aux montages de ces opérations et à la mobilisation des effets de leviers juridiques et financiers. Après une présentation du marché français des LBO, la seconde partie étudie l'évolution de la performance de la cible et la longévité de ces opérations.

A fully automatic 2D segmentation method for uterine fibroid in MRgFUS treatment evaluation
2015
PurposeMagnetic Resonance guided Focused UltraSound (MRgFUS) represents a non-invasive surgical approach that uses thermal ablation to treat uterine fibroids. After the MRgFUS treatment, an operator must manually segment the treated fibroid areas to evaluate the NonPerfused Volume (NPV). This manual approach is operator-dependent, introducing issues of result reproducibility, which could lead to errors in the subsequent follow-up phase. Moreover, manual segmentation is time-consuming, and can have a negative impact on the optimization of both machine-time and operator-time. MethodTo address these issues, in this paper a novel fully automatic method based on the unsupervised Fuzzy C-Means cl…
Trainability of underwater breath-holding-time
1982
From diving practice we know that breath-holding time (BHT) can be increased by training. This examination was set up to illuminate whether BHT underwater can be trained decisively in a short period of time. The authors investigated whether physiologic or psychological aspects are the main constituents of the above-mentioned BHT phenomenon. BHT and the "onset point" of involuntary respiratory movements of 64 subjects were registered after deep inspiration and immersion in ca. 1 m. Two different tests were set up: (I) 2 breath-holds per day on 5 consecutive days, (II) 5 repeated breath-holds with pauses of 3 min in between. BHT of the first test was shorter underwater than in similar experim…
Checklist of the Mammal Collection Preserved at the University of Palermo under the Framework of the National Biodiversity Future Center
2023
The latest reorganization of the Vertebrate collections preserved at the “Pietro Doderlein” Museum of Zoology of the University of Palermo (Italy) has made it possible to draw up a check-list of the Mammal taxa present in the stuffed (M), fluid-preserved (ML) and anatomical (AN) collections. The intervention was planned under the National Biodiversity Future Center (NBFC) agenda, focused on the enhancement of Italian natural history museums. The growing interest in museum collections strongly demands databases available to the academic and policy world. In this paper, we record 679 specimens belonging to 157 specific taxa arranged in 58 families and 16 orders. Most of the species (75.1%) co…

Enabling Energy Savings in Offshore Mechatronic Systems by using Self-Contained Cylinders
2019
This paper proposes a novel actuation system for an offshore drilling application. It consists of three self-contained electro-hydraulic cylinders that can share and store regenerated energy. The energy saving potential of the proposed solution is analyzed through a multibody system simulation. The self-contained system demonstrates superior energy efficiency compared to the benchmark system representing the state-of-the-art approach used today (i.e., valve-controlled cylinders by means of pressure-compensated directional control valves and counter-balance valves, supplied by a centralized hydraulic power unit). Due to the power on demand capability, the cancellation of the throttling losse…
Numerical and Experimental Study of a Novel Concept for Hydraulically Controlled Negative Loads
2016
This paper presents a numerical and experimental investigation of a novel concept that eliminates oscillations in hydraulic systems containing a counterbalance valve in series with a pressure compensated flow supply. The concept utilizes a secondary circuit where a low-pass filtered value of the load pressure is generated and fed back to the compensator of the flow supply valve. The novel concept has been implemented on a single boom actuated by a cylinder. A nonlinear model of the system has been developed and an experimental verification shows good correspondence between the model and the real system. The model is used for a parameter study on the novel concept. From the study it is found…
