TESTING AND PERFORMANCE EVALUATION OF A NUT-CRACKING MACHINE PROTOTYPE
Abstract: This study presents the design, construction and experimental testing nut-cracking machine prototype intended for household and small-scale farm applications (with emphasis on walnut, Juglans regia). The mechanical solution consists of a rotating cylindrical shaft and an adjustable reaction plate mounted inside a cracking chamber. A representative sample of one hundred walnuts was measured (dimensional statistics) and nine experimental trials were conducted with cracking gap settings between 26 mm and 41 mm; each test processed 1 000 g of nuts and categorized in fully cracked, partially cracked and intact kernels. Experimental analysis identified a narrow optimal gap range (≈30–31 mm) that maximizes intact-kernel yield. The prototype is suitable for household and small-scale farm use and can be further developed toward automation and higher productivity.

OF THE PLANE WHEEL TOOTH
ABSTRACT: In preceding research, the concept of Computer
Manufacturing Simulation (CMS) was developed by authors as a novel and
intuitive interface of 3D Computer Aided Design (CAD) systems used in
Virtual Reality (VR) engineering. Current research focuses on numerical
investigation of worm-face gear drives geometry and applicability of the CMS
method in simulation of face gear tooth kinematical generation. Firstly, a
novel program IGD (Interactive Graphic Design), for calculus and verification
of worm-face gear drives has been developed in a MathCAD environment.
Secondly, the paper concentrates on the virtual simulation of the face gear
tooth generation by CMS method. Numerical examples illustrate and validate
the developed approach.

STUDDY OF THE RESONANCE PHENOMENON
IN ALTERNATIVE CURRENT CIRCUITS
In general, the sources of electrical energy that supply electrical
circuits provide them with both active power, necessary for various uses, and
reactive power, corresponding to the variation of the energy stored in the
electric and magnetic fields of the network. In certain particular cases, it is
possible that while energy is accumulated in some of these fields, in the other
fields the energy decreases by an equal amount, the electric and magnetic
fields mutually supplying the necessary energy, so that the energy exchange
between the source and the fields in the circuit is zero at any time and –
correspondingly – the reactive power supplied by the source is also zero.
Although the circuit has reactive elements, it will absorb only active
power from the source. In this case, it is said that resonance phenomena occur
in the circuit

Abstract:This work was possible whit the results of engineering studies so far
where we found the solution and its application in a practical situation inherent in
the most diverse sphere of human activities. With the passage of time, even the
most successful and efficient mechanical constructions will be surpassed by the
dynamism of human progress. In this situation, man intervenes whit modern
solutions for modern challenges. In this case we applied practical solution of gear
reduction. We sought to use the existing space left over from the previous version
of the machine builder by combining as much as possible of the reducer elements
without affecting the aesthetic and resistance characteristics of the designed
reducer.
The new reducer makes a speed reduction from 400/RPM to 200/RPM
whit its operation even in overload mode through a correct dimensioning resulting
rom the strength calculation of the gear gears and by assigning a module of 5mm
to the wheels in the cassette.

EXPERIMENTAL STUDY ON THE INFLUENCE OF HEAT
TREATMENT REGIMES ON THE MICROSTRUCTURE AND
TOUGHNESS OF C45 STEEL
The present paper investigates the correlation between the heat
treatment parameters (normalization, quenching in various media,
return), the microstructural evolution and the shock fracture behavior of
C45 grade carbon steel. The study involved the application of heating
cycles at 900oC, followed by cooling in water, oil and air, as well as
successive tempering at 220oC and 600oC. The experimental results
demonstrated a reduced penetration of the quenching of C45 steel into
oil, where a heterogeneous structure of troostite and martensite 43 HRC
was obtained, compared to the fully martensitic structure obtained in
water 58 HRC. The analysis of fibrosity and crystallity of the fracture
surfaces highlighted the transition from brittle cleavage rupture (specific
to the hardened state) to tenacious, fibrous rupture (specific to the
improvement state), reaching a maximum value of KCU resilience of 112
J/cm2 after high recovery. The paper validates the importance of

35-3 MARIE CURIE, O ADEVĂRATĂ LUPTĂTOARE, O URIAȘĂ PERSONALITATE A ȘTIINȚEI

Această intrare a fost publicată în 2019 Volumul 35 și etichetată Mircea BEJAN la de

Maria Salomea Skłodowska (future Marie Curie) was born on November 7, 1867, in Warsaw. His father, Wladyslaw (1832-1902), was a professor of mathematics and physics, and his mother, Bronislawa (1836-1878), was a teacher, a family lacking financial resources. Physicist Marie Curie was the pioneer of radioactivity science – the study of penetrating rays emitted by rare materials. His work has revolutionized physics and chemistry, forming the basis for further research into nuclear physics. He discovered two elements unknown until then, and he also laid the foundations for an important research institute. In 1903, she shared the Nobel Prize for Physics with her husband, Pierre, with whom she worked, and with French scientist Henri Becquerel. In 1911, Marie was awarded the Nobel Prize for Chemistry. He died in France in 1934, after a long suffering, because of a radiation-related illness. In a survey conducted among the readers of the British BBC History Magazine, Marie Curie was voted the woman with the most significant impact on the history of the world. „She (Curie) was the first woman to win a Nobel Prize in Physics, the first female professor at the University of Paris and the first person to notice the use of the word person, not a woman, who won the second Nobel Prize, said Patricia Fara, president of the British Society for the History of Science, who nominated Marie Curie.

INTERNAL AND EXTERNAL JAMS, PROPOSED SOLUTIONS CONCERNING THE IMPROVEMENT OF THE ABSORPTION CAPACITY OF THE EUROPEAN STRUCTURAL FUNDS OF ROMANIA AS A MEMBER OF THE EUROPEAN UNION. INTRODUCTION

The European Union represents a regional policy framework associated with traditional interstate and geopolitical relations. There are many institutions within the European Union, including the European Commission, which carry out economic policies regarding the financial management of European funds together with EU member countries. The absorption capacity of the structural funds was acceptable until 1.01.2019 compared to the previous years, but was marked by internal and external bottlenecks, bureaucracy and inefficiency of the institutional structures. Following the evaluation of these problems, proposals were made in this study to improve the absorption capacity of the European structural funds. The implementation of European funds has led to the spread of democratic values, the rule of law, economic and social concepts among EU member states in the context of the globalization phenomenon. Through the extension, intensification and impact of these institutional relations at the level of all the EU members in economic, social and political aspect, flows and networks are developed in the EU region of activity, interaction centers and execution of power.

TEACHING TOOL – FACILITATOR TOOL OF COMPREHENSION

It is interesting to note that English use two different terms for the game: „game” and „game”, which designate two different practices. „Game” refers to free games without constraints whose end is unknown, while „game” refers to situations that have a clear end (a winner, a certain achievement). The history of the game in education is complex and has its roots deep in the wings of time. Renaissance humanism has always been associated, in an innovative way, with play and learning. Gargantua, the hero of Rabelais, plays cards to learn math. In the eighteenth century, Rousseau proposes a ludic approach to learning. Subsequently, the development of sciences allowed, at the end of the nineteenth century and the beginning of the twentieth century, the development of several theories that justify the use of the game in the process of learning. The play of children will be the support of psychoanalytic activity and the therapeutic valencies will be recognized. It can only be considered an unnecessary or just recreational activity ” [1].
