Authors: POPESCU Catalin Viorel , BORA Constantin , URECHIAN Viorica , ONCICA Fraga 
Published: December 2021

In the paper, there are presented the research results aiming the promotion of the conservative agriculture concept in variants/schemes adapted to:
- the soil’s properties (medium to heavy texture - 30-42 % clay in the arable layer)
- the main field crops cultivated in the sothern area of Romania,
in order to obtain competitive, qualitative and quantitative yields (similar to the ones obtained in the conventional agriculture), with lower costs and higher profit for the farmers by improving the soil’s properties and protecting the environment.
The highest yields were obtained in the first trial – seeding after ploughing. There are significant differences between these results and the results obtained in the trials with direct seeding, due to the fact that the luvosoil at Simnic Research and Development Station is a „cold” soil, with a higher clay content, a lower aeration porosity – it needs a better mobilisation.

This paper presents experimental data conducted for this purpose, during 2009 – 2010 in ARDS Turda. Species of Lepidoptera present in field crops, studied in ARDS Turda are: Agrotis segetum (Den. & Schiff.), Autographa gamma L., Amathes c-nigrum L., Mamestra brassicae L., Ostrinia nubilalis Hbn., Plutella xylostella L..
The research were performed at ARDS Turda, during 2009 - 2010 in crops: maize, sugar beet and soybean; were used F1 traps type) with synthetic sex pheromones of the Romanian Institute of Chemistry Cluj - Napoca. Traps were placed in 3 repetitions, at the 50 m distance between, during June-September. The adhesive used was based on polyisobutylene, produced by the same institute. Pheromones baits and sticky plates were changed at 10 days, when were recorded the number of captured Lepidoptera. To compare data obtained, was performed percentage distribution of species of Lepidoptera, and observations on the abundance of Lepidoptera pests, highlighting the appeal and sex pheromones specific for the most common Lepidoptera.
At ARDS Turda, in maize, sugar beet and soybean, under normal climate of the years 2009- 2010, were registered, in sex pheromones traps, more than 1.400 adults of the mentioned Lepidoptera species. These species showed a well defined allocation percentage as follows: Ostrina nubilalis represented a very significant percentage between 39.0 - 68.0% of the total of Lepidoptera pests, Autographa gamma 12,0-25,0%, Amathes c-nigrum 14,0-16,0% and other species (Mamestra brassicae, Plutella Xylostella, Agrotis segetum) between 2,0-11,0%.
The results have resulted in flight curves of the most common Lepidoptera pest crops, which shows the evolution of species according to specific climatic conditions, thus knowing the best time for applying treatments.

Published: December 2021

Seeded lawns is one of the most important links in the process of improving the forage base, ensure feed quality with high productivity. Mixtures of red clover crops (Trifolium pratense) with perennial grasses (Lolium multiflorum, Phleum pratense and Poa pratensis) has high productivity due to better utilization of ecological niches of the biotope (ROTAR I.et al.). These crops has advantages like high content of protein because of the red clover, economy-based fertilizer nitrogen from atmospheric nitrogen fixation by bacteria Rhizobium spp. located in the root of legumes. These seeded pastures get a balanced feed nutrients (proteins, carbohydrates, lipids), have a high palatability. The species Trifolium pratense has a greater capacity to restore the soil structure and also the enrichment of the macro-elements, like phosphorus and potassium (CARLIER L., et. al).
Our experience took place in the village Simonesti, Cobătesti village of the Harghita county. The experimental field was located respecting the experimental technique rules in randomized blocks with a technique that includes three variants based on red clover plus a perennial grass (Lolium multiflorum, Poa pratensis and Phleum pratense). Every version was fertilized with two types of fertilizer: one liquid (gull) and one solid (stable manure) in four different doses in all three variants. The doses were: V1 = 0 gull; V2 = 5 t / ha gull; V3 = 10 t / ha gull; V4 = 20 t / ha gulle and V1 = 0 stable manure; V2 = 10 t / ha stable manure; V3 = 30 t / ha stable manure and V4 = 50 t / ha stable manure.
In our studies we present the influence of fertilization with gull and stable manure on yield of green mass of all three variants. In general, both gull fertilization with manure favors grasses at the expense of installing legumes. The higher doses of fertilizer increase, the share of participant of grasses increases.

Published: December 2021

.Colloidal features [foaming capacity (FC); foam stability (FS) and foam density (FD)] of conditioning auxiliaries (additives) of plant protection active principles constitute, together with toxicity, a decisive technical index in forming administering receipts in modern ecological agriculture and foodstuff processing all during the agroalimentary processing and consumption chain.
In this paper we show the results of a study on a new class of superficial active compounds salefied polyether ( = 3 – 20) primary amides.
As diderived glymes, they have a guided regulation capacity of the HLB balance through the change of the medium degree of oligomerisation ( ) of the polyoxyethylene chain (PEO). Can thus obtain a wide range of structures such as micellar solute, dispersion, emulsion, and foaming agents, etc., through the cyanoethylation of polyethoxylated nonylphenols with a medium degree of oligomerisation ( ) between 3 and 20 structural oxyethylene units (EO) in alkaline catalysis with monomer acrylonitrile, followed by a classical hydrogenation in heterogeneous catalysis of intermediary nitrile thus obtained, and finally partial hysrolysis and salefied with HCOOH; CH3COOH.
These are biodegradable in water plants, which ensure special ecologlcal features and high compatibility within the restrictive legal ensemble of a foodstuff processing integrated in an extremely polluted environment. Structures have real bacteriostatical abilities compared to a wide spectrum of microrganisms (tested in studies related to this paper). Low toxicity of polyoxyethylene chains (PEO) together with that of other structural units in this polyether primary amides provide the studied glymes with a high compatibility in relation to environment and to plant and animal organisms of the food chain.

Published: December 2021

Agricultural sector faces several challenges, such as the increased need for management of production risks, fighting climate change, more efficient management of water, making the most of the opportunities offered by bio-energy and the preservation of biodiversity. One the best way of adjusting the CAP in order to meet these challenges is through Rural Development Pillar. Common argument is that using rural development measures can avoid some unintended consequences of agricultural policy, especially the increasing inequality within agricultural sector.
The farms’ capability of income generation and its competitiveness could be therefore increased,while strengthening rural economy. This paper is trying to highlight the choice made by EU farmers in order to take the advantages of different EU support actions. We will proceed to a comparative analysis of the content of the programmes and of their implementation at the level of some member states. Based on the existing databases and reports as of 30 September 2009 (Eurostat databases, European Environmental Agency databases and reports, DG AGRI statistical, monitoring and financial reports) we will try to assess the possible advantages of Romanian farmers

Published: December 2021

The goal of this study is to evaluate the possibilities to use the municipal sluge as a fertilizer in agriculture, especially upon alfalfa crop, with a very complex and precise methodology, in the conditions of assuring environment protection and human health integrity. The aim of this study is to determine the quality of alfalfa fourage derived from the application of city sludge from cleaning station Tetarom III ClujÂ - Napoca. Neutralizing city mud with the help of soil, considered a biological treatment station for water is one of the most important perspectives to protect the environment together with an increase of agricol production. In the new socio economical structures of Romania, the natural fertilizer is to be found less and less due to the decrease of the animal number, and also due to the way of their breeding, and the replacement of natural fertilizer with city sludge from the used water treatment, it is an alternative to use due to the sure advantages of the fertilized mud appliance.

Aim. Establishing of the ability to synthesize surface-active compounds by Pseudomonas aeruginosa bacteria isolated from the surface of Black Sea mussels. Methods. During the research several marine Pseudomonas spp strains isolated from petroleum hydrocarbon contaminated areas of Black Sea wereused: P. aeruginosa M1, P. aeruginosa M4 and P. aeruginosa PA01 as reference strain in suspension and biofilm cultures (LB and Giss media). Cultivation of Pseudomonas aeruginosa strains was performed at 37 °C for 120 and 168 hours. Planktonic culture growth was determined spectrophotometrically on the wave length 600 nm. Biofilm mass was determined spectrophotometrically on the wave length 592 nm by CV-test. The presence of surface-active compounds was determined in a drop test. The quantitative content of rhamnolipids was evaluated by the color reaction of rhamnose with orcin. Results. P. aeruginosa strains M1 and M4 isolated from Black Sea mussel’s surfaces synthesize 25% and 66% more surfactants than the reference strain PA01. All strains in Giss medium synthesized 10–20 times less rhamnolipids than in LB medium. In biofilm cultures the same biosurfactant synthesis dependence on the composition of the nutrient medium is observed as in suspension cultures. According to the intensity of rhamnolipid production in biofilm cultures, the studied strains can be arranged in the following row: P. aeruginosa M4 > P. aeruginosa M1 >> P. aeruginosa PA01.Conclusions. The strains of P. aeruginosa isolated from the Black Sea are more efficient producers of rhamnolipids than the reference strain of P. aeruginosa PA01; the intensity of biosynthesis of surfactants significantly depends on the composition of the nutrient medium and the method of cultivation.

Study of the Ferromagnetic Magnetite Resonance (Fe3O4) Forms of Thin Films Using Micromagnetic Simulation
Authors: Salsabila Syefira , Rohman Lutfi , Purwandari Endhah 
Published: December 2021

Fe3O4 is the strongest magnet among other iron oxides. Magnetite Fe3O4 is applied as a permanent magnet. The hysteresis curve of the permanent magnet Fe3O4 has a coercivity field that is not too large so that the material has a good chance to be applied as an absorbent material for RADAR waves. Micromagnetic simulations were carried out on Fe3O4 material in the form of thin film against hysteresis curves and ferromagnetic resonances at various thickness variations and side length variations, and the relationship was seen with changes in the bandwidth of the radar wave absorption frequency if the thickness variation of the simulated material had the same multiple as the experimental material. The thickness variations in this study were 60 nm, 90 nm, and 120 nm, where the variations in the experiment were 0.6 mm, 0.9 mm, and 1.2 mm. Micromagnetic simulation runs were performed to obtain the hysteresis curve and resonance frequency of the Fe3O4 material. The simulation results show that the resonant frequency increases with increasing thickness (fixed side length). Meanwhile, the relationship between the resonant frequency and the side length of the thin film is inversely related. Changes in the resonant frequency of Fe3O4 material are closely related to changes in the absorption frequency band of Fe3O4 material. The hysteresis curve obtained shows that the Fe3O4 material is a hard magnetic material. Changes in the resonant frequency of Fe3O4 material are closely related to changes in the absorption frequency band of Fe3O4 material. The hysteresis curve obtained shows that the Fe3O4 material is a hard magnetic material. Changes in the resonant frequency of Fe3O4 material are closely related to changes in the absorption frequency band of Fe3O4 material. The hysteresis curve obtained shows that the Fe3O4 material is a hard magnetic material.

Проаналізовано діяльність школи русофільського товариства «Львівський ставропігійський інститут» у міжвоєнний період. Показано, що основним завданням цього освітнього закладу було прищеплення русофільських поглядів молоді й те, що вона вивчала греко-католицький обряд, церковний спів, що давало випускникам змогу працювати дяками. В державній системі шкільництва ця установа виконувала допоміжну функцію. Утримуваний коштом Ставропігії при школі гуртожиток, який надавали або безкоштовно, або за невелику плату, уможливлював навчання дітей із бідних селянських родин у львівських гімназіях, технічних і народних школах.

ЗАХІДНА ІСТОРІОГРАФІЯ ГОСПОДАРСЬКОЇ РЕФОРМИ У СРСР 1965 Р.
Authors: Нефьодов Д. В. 
Published: December 2021

В статті досліджуються найважливіші тенденції у вивченні господарської реформи у СРСР 1965 р. західними науковцями. Автором визначені досягнення, головні ідеї та особливості західного історіописання проблеми. Західні науковці присвятили цій реформі чимало досліджень і коментарів, що цілком зрозуміло як з точки зору завдань, що стояли перед західною радянологією в той період, так і з урахуванням тих очікувань, які породила ця реформа в нашій країні та за її межами в перші роки її здійснення. Увага зарубіжних економістів до господарської реформи 1965 р. значною мірою виправдовувалася і тим, що на її прикладі можна було вивчити фундаментальні проблеми, пов’язані з функціонуванням економіки радянського типу, дати відповідь на питання про можливість «мирного співіснування» елементів централізації і децентралізації в радянській економічній системі.

Після виведення своїх військ з Афганістану СРСР підтримував режим НДПА в афганській кризі. На противагу усталеній в радянській та російській історіографії думці ми вважаємо, що Радянський Союз надалі лишався стороною конфлікту. Головними складовими політики СРСР щодо Афганістану в нових умовах були інститут військових радників, який було збережено, та широкомасштабні поставки зброї й військової техніки. Це призвело до ескалації афганської кризи, а також подальшого виснаження економіки CРСР в останні роки його існування.

Field robotics has been undergoing rapid progress in recent years. It addresses a wide range of activities performed in outdoor environments, and its applications are being developed in areas where it was previously considered difficult to apply. This rapid progress is largely supported by AI-based improvements in computer vision systems with monocular cameras, stereo cameras, RGB-D cameras, LiDAR systems, and/or other sensors. Field robotics is impelled by an application-driven approach by its nature, and it contributes to the resolution of social problems and the creation of new innovations, including autonomous driving to reduce casualties, autonomous working machines/robots to resolve the problems of labor shortages or dangers, disaster-response robots to aid rescue parties, various kinds of aerial robots to do searches or make deliveries, underwater robots to perform search missions, etc.
In this special issue on “Field Robotics with Vision Systems,” we highlight sixteen interesting papers, including one review paper, fourteen research papers, and one development report. They cover various application areas, ranging from underwater to space environments, and they propose interesting integration methods or element technologies to use in outdoor environments where vision systems and robot systems have great difficulty performing robustly.
We thank all authors and reviewers, and we hope that this special issue contributes to future research and development in area of field robotics, which promises new innovations.

Published: December 2021

Despite a significant amount of work in the field of mechanically doped alloys and, above all, based on aluminum and copper, research aimed at creating mechanically doped alloys is extremely limited. In this regard, the following work aimed at to establishing the regularities of the formation of the phase composition, structure, and properties in the implementation of the technology for obtaining mechanically doped heat‑resistant steels, is important and relevant.The basis for the development of mechanically doped alloys were the results of long‑term research carried out at the Belarusian‑Russian University and aimed at studying mechanically and thermally activated structural phase transformations taking place at all the technological stages of obtaining mechanically doped metal alloys. In this article, in a generalized form the final research results are presented, revealing the patterns of these transformations, which are a reliable scientific basis for the creation of mechanically doped complex‑hardened heat‑resistant steels.
