Research On The Subject Of Nutrition In Physical Effort Determination
Authors: Martinescu Fabiana 
Published: May 2018

Abstract
Living organisms are in close dependence with the environment.
There is also a permanent exchange of substance, energy and information between the human body and the environment, an exchange that underlies the development of all biological processes. In the normal biological processes, the essential environmental factors compete, among which we mention the air, water and food. The importance of food (lat. alimentum - aliment)consists of the intake of nutrients necessary for all life processes.
The substances from food are generically described by the term “nutrient principles” or “food principles”, often being used the term “nutrients”. Among nutrients, depending on their amount in the food products and the physiological and biochemical role, there are the macronutrients (carbohydrates, lipids and protides), micronutrients (mineral compounds of biological interest and vitamins) as well as other nutrients (water, fibres, biologically-active substances).
Building A Nutritional Plan To Support Prolonged Exercise
Authors: Martinescu Fabiana 
Published: May 2018

Abstract
Over the years, we have heard numerous discussions and views on the nutritional plans for the bodybuilding and fitness practitioner. The most controversial meal of the day is with no doubt the dinner. Supporters of the principle according to which dinner should be eliminated and the last meal of the day should be taken in the afternoon, support their theory with solid arguments, at least theoretically. The others, more tolerant, recommend that dinner is taken at least one hour before going to bed and the latter bring relevant counterarguments to support their opinion. It is no less true that what, how much and when you are eating in the evening is essential in achieving the set goals. For example, for someone interested in increasing body weight and muscle, dinner and its caloric intake is particularly important. On the opposite end are those who want to lose weight and even more, want to keep their muscle. They will definitely not try to get more calories, but will be interested in where these calories come from.

Authors: Křivý V. , Kreislová K. , Urban V. , Vavrušová K. 
Published: May 2018

Abstract
This article presents the program of experimental atmospheric
corrosion test of weathering steels. This program
is designed as a long-term project. Attention is paid to study
of corrosion processes at different structural elements of
supporting structures of bridges. Measurements of corrosion
losses and average thicknesses of corrosion products are carried
out within this experimental program. Protective ability
of corrosion products is evaluated using X-ray diffraction
analysis. The article presents results of corrosion tests after
one year of exposure of corrosion specimens. It results from the
tests that corrosion losses of weathering steels are signifi cantly
conditioned by position and location of exposed surface within
the structure.
Flexible binders, their degradation and impact on cement substrate
Authors: Knotek V. , Kučerová I. , Horáková T. , Peterová A. 
Published: May 2018

Abstract
Compared to the traditional inorganic binders based on
mortar or plaster, cementing clefts and cracks with polymer
fl exible binders is effective in terms of better adhesion and fl exibility.
Nevertheless, in order to be applicable in restoration
practice they must comply with the condition of a minimum impact
on the substrate, which frequently is a porous material.
Silicon-based binders, synthetic rubber and hybrid binders based
on silicone modifi ed with polyurethane and polyether were
tested in this study. The binders were artifi cially aged under
various conditions. At the same time, the study also focused on
the extent of infl uencing of the porous cement substrate by the
application of binders. The silicone binders showed the best
resistance to artifi cial aging, however, the originally hydrophilic
substrate became hydrophobic. Hybrid binders showed better
resistance to moist rather than dry atmosphere. Testing in
the QUV panel caused cracking and incoherence of all hybrid
bonders. Various categories of binders showed similar properties
in terms of resistance to aging and the extent of infl uencing
of the porous substrate. The porous cement substrate was
reported to be substantially infl uenced by all tested binders.
Therefore, none of the tested binders can be unambiguously
recommended for application in restoration practice.
Shakespeare Re-Read, Re-Written, Re-Contextualised Or... Re-Placed in Opera and Musical
Authors: Bottez Alina 
Published: May 2018

Abstract
Shakespeare thrives not only in the theatre, but also through what Bolter and Grusin call remediation. This article analyses how opera and musical reread Elizabethan drama shifting from spoken to sung discourse and travelling transnationally, temporally and across genres. Its main approach is comparative and relies on the history of mentalities. Rereading is dictated by cultural context, the conventions of the lyrical theatre, social and political factors and reception. Gender is reread in Bellini‘s I Capuleti e i Montecchi and in Britten‘s A Midsummer Night‟s Dream, and religion - in Gounod‘s Roméo et Juliette and Bernstein‘s West Side Story. Cultural and historical barriers enjoin recontextualisation: the English, French and Welsh verbal fun in The Merry Wives is metamorphosed into Germ-Italian in Salieri‘s Vienna, while prayer is bowdlerised in Bentoiu‘s Hamlet written in communist Romania. Porter‘s Kiss Me, Kate rewrites The Taming of the Shrew in a post-modern musical avant la lettre featuring the cast of a theatre company on- and off-stage. However, operas such as Rossini‘s Otello or Thomas‘s Hamlet are shown to have almost replaced Shakespeare‘s initial message. The article emphasises the idea that operations of rereading and rewriting, in a musical context, significantly enrich the ample panoply of Shakespearean adaptations.

Effects of Using Channelling Devices to Increase Efficiency of Hydrokinetic Devices
Authors: Kalnacs A. , Kalnacs J. , Mutule A. , Entins V. 
Published: May 2018

Abstract
In the rivers of Latvia and of many other countries the flow velocity in the places that are most suitable for installation of hydrokinetic devices is 0.4 to 0.9 m/s. In a stream or a river the hydrokinetic devices can reach full efficiency starting from about twice higher flow velocities. It is advisable to at least double this velocity thus increasing the efficiency and power output of the hydrokinetic devices installed in such places. Since Latvia has abundance of slow rivers and almost none are fast, research in this field is of high importance. Diversified technical methods are known that allow increasing substantially the efficiency of hydrokinetic devices. These methods include the use of diffusers, concentrators, different types of other channelling devices and means of flow control. Desirable effects are achieved through changing the cross-section and/or direction of a flow, its pressure, minimizing the turbulence, etc. This work substantiates the use of such devices for increasing the efficiency of hydrokinetic devices. A method is proposed for evaluation of the effects on power output gained owing to the use of channelling devices. Results show that the efficiency of hydrokinetic devices can be increased by at least 110%.
Numerical 2D And 3D Simulations of a Spherical Fabry–Pérot Resonator for Application as a Reference Cavity for Laser Frequency Stabilisation
Authors: Nitiss E. , Bluss K. , Alnis J. 
Published: May 2018

Abstract
We report on the results of a numerical study of deformations of a spherical Fabry-Pérot cavity that can be used for laser frequency stabilisation. It is demonstrated that for a precise simulation of the cavity deformations a 3D model has to be used instead of a simpler 2D model, which employs simulation on the symmetry plane of the cavity. To lower the sensitivity to environmental perturbations, it is suggested to use a material with a low density and a high Young’s modulus. We also show that the mechanical resonance frequencies of the cavity are mainly determined by the size of the cavity.

Authors: Ozoliņš A. , Jakovičs A. , Gendelis S. 
Published: May 2018

Abstract
The aim of the current paper is to analyse thermal comfort and overheating risks in the low-energy buildings in a summer season under Latvian climate conditions both experimentally and numerically. An interior temperature and relative humidity are analysed under free-floating conditions. Two cases are analysed: in one case, the solar influence through the window is taken into account; in the other this influence is omitted. Three different building solutions are observed: two building structures which mainly consist of the mineral wool and wooden materials and one structure from aerated clay bricks and mineral wool. The experiments have been implemented in test stands in Riga, Latvia. The numerical simulations based on measurements obtained from test stands have been performed using software WUFI Plus. The results show that the wooden constructions have high overheating risks.
Time and Frequency Synchronization on the Virac Radio Telescope RT-32
Authors: Bezrukovs V. 
Published: May 2018

Abstract
One of the main research directions of Ventspils International Radio Astronomy Centre (VIRAC) is radio astronomy and astrophysics. The instrumental base for the centre comprised two fully steerable parabolic antennas, RT-16 and RT-32 (i.e. with the mirror diameter of 16 m and 32 m). After long reconstruction, radio telescope RT-32 is currently equipped with the receiving and data acquisition systems that allow observing in a wide frequency range from 327 MHz to 9 GHz. New Antenna Control Unit (ACU) allows stable, fast and precise pointing of antenna. Time and frequency distribution service provide 5, 10 and 100 MHz reference frequency, 1PPS signals and precise time stamps by NTP protocol and in the IRIG-B format by coaxial cable.
For the radio astronomical observations, main requirement of spatially Very Long Base Line Interferometric (VLBI) observations for the observatory is precise synchronization of the received and sampled data and linking to the exact time stamps. During October 2015, radio telescope RT-32 performance was tested in several successful VLBI experiments. The obtained results confirm the efficiency of the chosen methods of synchronization and the ability to reproduce them on similar antennas.

Dynamic Models of a Home Refrigerator
Authors: Schné Tamás , Jaskó Szilárd , Simon Gyula 
Published: May 2018

Abstract
Home refrigerators produce a substantial part of the annual power consumption in an average household. To further improve the efficiency of these devices, new intelligent control solutions are required. These solutions necessitate the behaviour modeling of the refrigerators.
We seek models with as simple structure as possible, since future intelligent controllers may use such models in real time, thus their evaluation must be feasible even on simple microcontrollers. We investigate various dynamic models to describe the behavior of the refrigerator, i.e. the cool-down and warm-up phases.
For model parameter identification real data was collected from a real home refrigerator. Data processing, modeling and the parameter identification were performed in MATLAB environment.

Published: May 2018

Abstract
The project of a canal connecting the three major Central European Rivers: the Danube, Oder and Elbe, is incorporated into a planned trans-European transport network system. Geographically, the course of the planned canal stretches into the territory of four Central European countries, predominantly that of the Czech Republic. The environmental impacts of the potential construction and operation of the Danube–Oder–Elbe (DOE) Canal is currently widely discussed by experts from various fields. This paper aims to assess some potential impacts of the canal on the alluvial landscapes in the Czech Republic. The method of geo-ecological assessment presented here applies GIS analyses at the larger landscape scale. The results of the geo-ecological assessment of potential impacts of the DOE Canal on the land-use of river floodplains, the fluvial dynamics of streams and the extent of their alluvial plains, and the quantified DOE Canal impact on protected areas and groundwater sources, are presented. The hydrological impact of the DOE Canal will affect a total of 1,975.4 km2 of river basins in the Czech Republic. The DOE Canal will affect 157 sites significant from the perspective of landscape and nature conservation, 7 nature parks and 113 existing water points which are used as groundwater sources. The results show that the most significant disruption of fluvial dynamics of the stream sediment regime would occur in the Protected Landscape Area of Litovelské Pomoraví. In general, the geo-ecological impact of the DOE Canal on the landscape will be very important.

Authors: Filip-Vacarescu Norin , Vulcu Cristian , Dubina Dan 
Published: May 2018

Abstract
This paper discusses the concept of a hybrid damper made from a combination of two dissipative devices. A passive hysteretic device like steel Buckling Restrained Brace (BRB) can be combined with a magneto-rheological (MR) Fluid Damper in order to obtain a hybrid dissipative system. This system can work either as a semi-active system, if the control unit is available, or as a passive system, tuned for working according to performance based seismic engineering (PBSE) scale of reference parameters (i.e. interstory drift).

Published: May 2018

Abstract
Introduction. Heart function in pregnancy is a subject of many debates and studies. A large number of epidemiologic studies have found association between preeclampsia and cardiovascular morbidity/mortality. About 5-8% of deliveries are complicated with preeclampsia. Until recently, heart damage associated with preeclampsia has not been studied. A number of heart difficulties only appear long after the reproduction period has ended. Preeclampsia increases the risk for B stage (asymptomatic) of heart failure.
Case report. A 37-year-old pregnant patient, G2P1 27 weeks of gestation, paid her first visit to the Gynecology Outpatient Clinic. She complained on heavy breathing, difficulty with movement and hypertension. She was referred for further evaluation to the Cardiology Outpatient Clinic with a suspicion of gestational hypertension and heart abnormalities.
The pregnancy was evaluated several times at the Out-patient Clinics of Gynecology and Cardiology with the diagnosis of gestational hypertension. Echocardiography showed abnormal heart remodeling. In the 36 g.w laboratory findings showed urine dip stick ++,ТА160/110. The diagnosis was changed to preeclampsia. The patient was delivered with a re-caesarean section because of previous S.C and preeclampsia. Postpartum echocardiography confirmed left chamber hypertrophy with persistent hypertension.
Results. Clinical cardiovascular complications in preeclampsia continue long after the pregnancy has ended. Studies show that pregnancies with both early and late preeclampsia have an increased risk for asymptomatic left chamber dysfunction/hypertrophy and essential hypertension in the next 2 years after delivery. If the damages are caught early prevention can be started sooner rather than later before patients become symptomatic (C stage of heart failure).

Authors: Poposka Simonida Kotlarova , Jovanoski Afrodita Stomnaroska 
Published: May 2018

Abstract
The aim of this paper is to present the new laser technology using erbium laser JAG various minimally invasive, non-surgical procedures in gynecology. The laserhas its effect through photothermal action, leading to reconstructtion and stimulation of new collagen synthesis in the vaginal walls and fascia of the pelvic floor muscles. This results into hardening and tightening of the vaginal walls, which contributes to better leverage of the bladder and urine retention. In gynecology this laser treatment is used for treatment of vaginal walls failure, stress urinary incontinence, pelvic organ prolapse and vaginal atrophy. From 2010 to 2014 several clinical studies were conducted, all of them about the use of laser in the treatment of these 4 conditions and the aim was to confirm the efficacy and safety of this technology. The results showed that SMOOTH mode erbium laser is an effective and safe method for treatment of vaginal walls weakness, stress urinary incontinence, pelvic organ prolapse and vaginal atrophy.

Published: May 2018

Abstract
Introduction. Being a default transradial access center we have encountered the need for alternative to the right radial artery. Determining the most frequent alternative access strategy for PCI in STEMI patientswasthe focus of our study. We sought to analyze whether the wrist access strategy impacts procedure time and success rate particularly for the STEMI interventions where time is of paramount importance.
Methods. During four years, in our Center 2624 consecutive all-comers STEMI patients underwent urgent coronary intervention. TRA was used as the first-choice access strategy. We sought to assess crossover rate and safety of preferable access strategy. Crossover occurred according to the operator's decision. Primary outcomes were: access site crossover rate and In Lab time, secondary outcomes were PCI time, X-ray time, mortality and MACE at 30 days and at 6 months.
Results. Overall crossover rate from default radial was 5.4% (144 out of 2624 patients). We treated 98.7% (2589) patients by wrist access and only 1.3% (35) patients with TFA. Crossover towards left radial occurred in 47.9% (69 out of 144 patients), towards ulnar 27.8% (40 patients) and towards TFA only 24.3% (35 patients). The meanIn-Lab time 40.4±17.7 minutes, PCI time was 21.4±7.4 min, X-ray time 9.2±4.7 minutes. Survival outcomes at 30 days were: MACE rate of 6.6% (174 patients), mortality rate of 5.0% (131 patients). At six months MACE rate was 8.6% and mortality rate was 5.6%.
Conclusions. Default radial access is associated with alow crossover rate. Crossover towards femoral occurred less frequent than ulnar artery access.Complete wrist access strategy is safe and feasible for STEMI interventions with low mortality and MACE rate in unselected all-comers cohort.
