Personalities of the scientific universe: Hermann Oberth

MANOLEA, Gheorghe (Technical University of Moldova, 2016)
Teaching creativity and inventive problem solving in science

DULGHERU, Valeriu (Technical University of Moldova, 2016)
Elaboration and design of the planetary precessional transmission

BOSTAN, I.; DULGHERU, V. (Technical University of Moldova, 2016)

Some problems of mechanical transmissions can be solved with special effects by developing new types of transmissions based on planetary precessional transmissions with multiple gear, that were developed by the author. ...
Vibroacoustical diagnosis of planetary precessional kinematical transmission

MALCOCI, Iu.; BODNARIUC, I. (Technical University of Moldova, 2016)

An ideal dynamical system should not generate any vibrations, because vibrations mean a loss of energy. Vibration in planetary precessional gear box occurs at bearings, gear wheels, misaligned shafts, imbalance rotating ...
The determination of the melting time of the particle by spraying in the plasma jet

DÂNTU, Sergiu; IVANOV, Leonid; GALUŞCA, Eduard (Technical University of Moldova, 2016)

The quality of the deposited layers by spraying in the plasma jet is determined by several factors: the powder material and the surface of the base material, the thermo-physical properties of the material, the temperature ...
The impact of season on Ash content in local goat milk

BULGARU, Viorica; GUTIUM, Olga (Technical University of Moldova, 2016)

Within the same species and breeds the lactation period has a great influence on the total ash content. Milk collected in December compared with samples in August has a larger increase in ash content, this increase is more ...
Characteristics and trends in the development of local footwear industry

GHELBET, Angela (Technical University of Moldova, 2016)

Light industry of the Republic of Moldova is an important sector of the national economy. Articles of clothing, footwear and other consumer goods represent the object of business for this industry. Most businesses are SMEs, ...
The assessment of rheological behavior of a beam propped on the environment with viscoelastic properties

ȚIBICHI, Viorica (Technical University of Moldova, 2016)

Deformation of bodies changing over time until reaching the balance between internal and external forces. In the present work, for description of the rheological behaviour of the beam resting on the deformable medium, was ...
The formation and testing of the tribological layers sprayed in the plasma jet

GALUŞCA, Eduard (Technical University of Moldova, 2016)

The materials used for installations from the food industry, demand special requirements - as high resistance to wear, corrosion... To solve some of these problems, so to increase the tribological proprieties and also to ...
Quality of local goat milk depending on the season

BULGARU, Viorica (Technical University of Moldova, 2016)

Goat milk quality depends on factors such as breed, number and stage of lactation, health status, region, diet, and has a predominant influence on the quality of subsequent goat milk products. The main objective of present ...
SCADA system application in wastewater treatment plants

CIOBANU, N.; BUŢANU, V.; SECRIERU, N.; UNGUREANU, D. (Technical University of Moldova, 2016)

The modality traditional management and maintenance of WWTP plants is very inefficient or impossible, therefore it found advantageous to implement a management system, enabling the state to identify complex data acquisition, ...
Composite material test results and finite element analysis: its correlation

GUŢU, Marin (Technical University of Moldova, 2016)

In this paper are presented some aspects regarding the method of simulation of composite materials testing with finite element analysis software. There were simulated tensile and shear tests of specimens manufactured from ...
Increasing the durability of expanded clay lightweight concretes for thin-walled hydraulic engineering structures

MISHUTIN, A. V.; KROVIAKOV, S. O.; ZAVOLOKA, M. V.; BOGUTSKY, V. L.; STANCHYK, Ie. V. (Technical University of Moldova, 2016)

This article reveals that modified expanded clay lightweight concrete can be effectively used for construction of thin-walled hydraulic engineering structures. Influence of the composition of lightweight concrete on its ...
Investigation of hydration processes of nanomodified calcium sulfate hemihydrate

DEREVIANKO, V. N.; KONDRATIEVA, N. V.; SANITSKIY, N. A.; HRYSHKO, H. M. (Technical University of Moldova, 2016)

This article presents the results of the investigation of gypsum hydration processes in the presence of carbon nanomodifiers. The hemihydrate calcium sulphate molecule interaction with graphene-like surface is the chemical ...
Speckle pattern of radiation scattered of soft biological tissues. Light fields outside tissue

ABRAMOVICH, Nicolai; DICK, Serghei; SONTEA, Victor (Technical University of Moldova, 2016)

Speckle patterns observed by reflected light from a multi-layered skin tissue are theoretically studied. Biological and optical factors related with volume concentration of melanin in epidermis and of blood in dermis, which ...
Energy conversion, consumption and conservation

BOSTAN, Viorel; BOSTAN, Ion; DULGHERU, Valeriu (Technical University of Moldova, 2016)

Today, most of the energy needed for daily consumption is produced by burning fossil fuels - coal, oil and natural gas. Several million years, plants and animals decomposing led to the formation of fossil fuels, which, ...
State of the art of photovoltaics

BĂJENESCU, Titu-Marius I. (Technical University of Moldova, 2016)

The current and future trends in photovoltaic cells and systems are reviewed in this paper. Solar electricity is more expensive than that produced by traditional sources. But over the past two decades, the cost gap has ...
