PIG CARCASS CLASSIFICATION IN ROMANIA: A DISSECTION TRIAL FOR THE APPROVAL OF THE “FAT-O-MEAT’ER” AND OF THE “OPTIGRADE-PRO”EQUIPMENT
2014
The objective of this study was to obtain new regression formulas for optical equipment Fat-O-Meat’er and OptiGrade-PRO in pig carcass classification in Romania. The estimation of lean mean content in pig carcasses by means of SEUROP system and following fair payment based on the weight and composition of the carcass pigs in the main objective of classification. Dissection of four main cuts (shoulder, loin, ham, belly) of pig carcasses (n = 145) were performed. The measurement of backfat and muscle depths using probes were taken from the carcasses within 45 min. after slaughter of pigs. Lean meat content estimated using different methods and determined from dissections was equal (56,3 % ). …
Effects of Polyacrylic Acid Pre-Treatment on Bonded-Dentine Interfaces Created with a Modern Bioactive Resin-Modified Glass Ionomer Cement and Subjec…
2018
Objectives: Resin-modified glass ionomer cements (RMGIC) are considered excellent restorative materials with unique therapeutic and anti-cariogenic activity. However, concerns exist regarding the use of polyacrylic acid as a dentine conditioner as it may influence the bonding performance of RMGIC. The aim of this study was to evaluate the effect of different protocols for cycling mechanical stress on the bond durability and interfacial ultramorphology of a modern RMGIC applied to dentine pre-treated with/without polyacrylic acid conditioner (PAA). Methods: The RMGIC was applied onto human dentine specimens prepared with silicon-carbide (SiC) abrasive paper with or without the use of a PAA c…
Pro-Degradant Activity of Naturally Occurring Compounds on Polyethylene in Accelerate Weathering Conditions
2019
In this work, naturally occurring compounds, such as Vitamin E (VE) and Ferulic Acid (FA), at high concentrations, have been considered as pro-degradant agents for Low Density Polyethylene (PE). However, all obtained results using the naturally occurring molecules as pro-oxidant agents for PE have been compared with the results achieved using a classical pro-oxidant agent, such as calcium stearate (Ca stearate) and with neat PE. The preliminary characterization, through rheological, mechanical and thermal analysis, of the PE-based systems highlights that the used naturally occurring molecules are able to exert a slight plasticizing action on PE and subsequently the PE rigidity and crystalli…
Ventspils pilsētas iedzīvotāju sociāli ekonomiskais portrets 19. gadsimta beigās
2020
Maģistra darba “Ventspils pilsētas iedzīvotāju sociāli ekonomiskais portrets 19. gadsimta beigās” mērķis ir konstatēt Ventspils pilsētas iedzīvotāju sociālā portreta iezīmes 19. gadsimta beigās sākot ar 1877. gadu, kad tika ieviesti jaunie pilsētu likumi, līdz 1897. gadam, kad notika Krievijas impērijas pirmā vispārējā tautskaite. Šādā skatījumā Ventspils pilsēta vēl nav tikusi pētīta, tādēļ darbs ir būtisks pienesums 19. gadsimta vēstures historiogrāfijā. Darbā analizēti tautskaites statistiskie dati par Ventspils iedzīvotāju sociālo un etnisko struktūru, skaidroti statistikas datu cēloņi un būtība, kā arī konstatētas galvenās pilsētas iedzīvotāju sociālā portreta īpatnības. Uzmanība pievē…
Closed tank pneumatic press application to improve Sauvignon Blanc wine quality and nutraceutical properties
2019
The machines used in the winemaking process directly affect the quality of wine and its nutraceutical properties. Grapes-pressing is a very important step in winemaking as it may promote the presence and/or absence of enzymatic processes on the must, leading to the creation of different products in terms of chemical composition, starting from the same grapes. The aim of the study was to compare two different pressing systems of Sauvignon Blanc grapes using an innovative pneumatic discontinuous closed tank press in two operating modes: the traditional pressing mode in presence of oxygen and the inert pressing mode, performed through grapes pressing under inert gas with nitrogen recovery. Che…
Halogen Bonds in 2,5-Dihalopyridine-Copper(I) Halide Coordination Polymers
2019
Two series of 2,5-dihalopyridine-Cu(I)A (A = I, Br) complexes based on 2-X-5-iodopyridine and 2-X-5-bromopyridine (X = F, Cl, Br and I) are characterized by using single-crystal X-ray diffraction analysis to examine the nature of C2&minus
INTEGRATED SYSTEMS IN PLANT PROTECTION MANAGEMENT: FIRE BLIGHT OF ROSACEOUS PLANTS (Erwinia amylovora (Burrill) - Winslow) IN AN APPLE ORCHARD IN SIB…
2013
Integrated protection represents a modern approach, denoting a protection strategy of agro-ecosystems; and it represents a complex system employing all appropriate methods in a manner as consistent and smooth as possible, in order to maintain the biocenotic balance of agrosystems and to keep pathogens at a level at which they do not cause economic damage (so-called level of eco-efficiency). A biocenotic approach to issues of agrosystem protection against disease attack requires an acknowledgement of all aspects regarding the evolution of pests in time and space, so as to be able to intervene at the right time with all possible means. And such protection measures are not supposed to restrain…
Harry Francis Mallgrave. L'empatia degli spazi. Architettura e neuroscienze
2015
Le informazioni che possiamo acquisire sul molteplice aspetto della realtà passano attraverso la percezione sensoriale che il nostro corpo ha dell’esterno. La relazione fra il corpo e l’architettura è proprio il tema centrale intorno al quale si snoda il libro di Harry Francis Mallgrave che, in quanto pioniere degli studi sull'applicazione delle neuroscienze alla teoria architettonica, svela attraverso "L’empatia degli spazi" la potenza e la forza del corpo nel costruire le forme della realtà. Information we can acquire on the multiple aspect of reality passes through sensory perception that our body has of the outside. The relationship between body and architecture is the central topic of …
STUDY CONCERNING FOREST ECOLOGIC RECONSTRUCTIUON ON DEGRADED LAND IN RANGE OCOLUL SILVIC “VALEA CIBINULUI”, SALISTE, ROMANIA
2014
The study examines the stationary conditions, determine solutions to improve degraded land, assessing the cost of ecological restoration work needed in the area of improving degraded lands at Rapa - Copăcel, estimated benefits of the project and its viability. Objectives of the paper: need to introduce in the circuit of productive forest lands within the improvement of the area "La Rapa - Copăcel" danger zone where activation of the phenomena of degradation (erosion , landslides ) predominate. Out of 102.33 ha as area for improvement, the effective area of 101.6 ha is forested, representing a difference of 0.73 ha, 1.2 m wide strip that is to be the place for hedges.
