THE TRIAL OF GALILEO GALILEI BY THE ROMAN INQUISITION: A COMPREHENSIVE OVERVIEW
Full text linkOne of the most famous trials in world history is that of the Florentine scientist Galileo Galilei in front of the Roman Inquisition. Based on historical sources, this article presents a comprehensive overview of the 1633 trial, the roots of which dated to Galileo’s 1613 publication on sunspots. It culminated with his publication of the Dialogue concerning the two chief world systems, Ptolemaic and Copernican. Although condemned by the Inquisition to imprisonment for an indefinite period, his sentence was commuted to house arrest until death
IMPLEMENTATION OF PLASTIC RECYCLING STRATEGIES IN THE REPUBLIC OF MOLDOVA. CASE STUDY
Full text linkThe present study examines the implementation of national sustainability strategies derived from European policies and global environmental concerns, focusing on ensuring a sustainable future for future generations. Given the environmental impact of plastic, as well as its non-biodegradability, the research analyzes the national and European legal framework that recommends a series of strategies and measures aimed at mitigating environmental impact while fostering a culture of sustainability from an early age at the national level. To conduct the study, multiple research methods were employed, including direct observation, systemic analysis, case studies, circular document analysis, data collection methods, and comparative analysis. The study’s findings indicate that, at the national level, the first companies dedicated to recycling specific types of plastic and reintegrating them into the economic cycle as equally necessary and widely used products have been established. Additionally, various awareness and promotional campaigns highlight the importance of recycling used plastic packaging, a culture of environmental responsibility is gradually emerging among users of all age groups. The novelty of this study lies in its exploration of the interconnection between the legal, academic, and economic spheres in addressing sustainability and environmental protection. This integration positions the national approach within the broader framework of global sustainability strategies

COMPONENȚA TAXONOMICĂ A COMUNITĂȚILOR PROCARIOTE DIN CERNOZIOMUL TIPIC ȘI ABUNDENȚA LOR LA NIVEL DE FILUM
Full text linkIn the present study, the changes in the taxonomic composition of prokaryotes at the phylum level in the typical chernozem of the Republic of Moldova during the years 2020-2022 were determined, using the polymerase chain reaction (PCR). The group of microorganisms studied is characterized by a genetic diversity, whose spectrum comprises 15 phyla with a different prevalence in the prokaryotic community. The majority (14) belong to the Bacteria domain: Bacteria: Proteobacteria, Actinobacteriota, Bacteroidota, Firmicutes, Verrucomicrobiota, Acidobacteriota, Planctomycetota, Myxococcota, Nitrospirota, Gemmatimonadota, Cyanobacteria, Patescibacteria, Fibrobacterota, Chloroflexi and one to the Archaea domain – Thaumarchaeota. The pool of the representatives of the Bacteria domain (82,16-88,32%) was also differentiated by the highest indices in relation to the representatives of the Archaea domain. At the same time, the representatives of the Archaea domain, registering a share of 11,6-17,84% in the years of study, were among the phyla with the highest abundance and yielded only to the phyla Proteobacteria (25,11-31,21%) and Actinobacteriota (24,01-26,46%), which held the lead according to this indicator. The study demonstrated that the prokaryotic composition of the studied chernozems varied from yeat to year, so their taxonomic structure can serve as an important indicator of previous changes in the diversity and composition of prokaryotic communities as a result of agricultural land use.
În studiul de față au fost stabilite modificările compoziției taxonomice ale procariotelor pe parcursul anilor 2020-2022 la nivel de filum în cernoziomul tipic al Republicii Moldova, folosind reacția în lanț a polimerazei (RLP). Grupul de microorganisme studiate se caracterizează printr-o diversitate genetică, spectrul cărora este alcătuit din 15 filumuri cu o prestanță diferită în comunitatea procariotelor. Majoritatea lor (14) aparțin domeniului Bacteria: Proteobacteria, Actinobacteriota, Bacteroidota, Firmicutes, Verrucomicrobiota, Acidobacteriota, Planctomycetota, Myxococcota, Nitrospirota, Gemmatimonadota, Cyanobacteria, Patescibacteria, Fibrobacterota, Chloroflexi și unul domeniului Archaea – Thaumarchaeota. Pool-ul reprezentanților domeniului Bacteria (82,16-88,32%), de asemenea, s-a deosebit prin cei mai înalți indici în relație cu domeniul Archaea. Totodată, reprezentanții domeniului Archaea, înregistrând o pondere de 11,6-17,84% în anii de studiu s-au plasat printre filumurile cu cea mai mare abundență cedând doar filumurilor Proteobacteria (25,11-31,21%) și Actinobacteriota (24,01-26,46%), care dețineau întâietatea după acest indicator. Studiul a demonstrat că compoziția procariotelor cernoziomului studiat variază de la an la an, astfel încât structura lor taxonomică poate servi ca un indicator important al modificărilor anterioare în diversitatea și compoziția comunităților procariote ca urmare a utilizării terenurilor agricole
CAPACITĂȚILE PRODUCTIVE A HIBRIZILOR FORMAȚI PRIN UTILIZAREA DIFERITOR TIPURI GENETICE DE SUINE
Full text linkThe paper presents the experimental results regarding the influence of the genetic types of boars on the productive qualities and the specific feed consumption of hybrids, as well as its modification in the growth and fattening process with the increase in the age of the pigs. The object of the study was different genetic boar types: purebred Pietrain and Duroc, as well as Duroc x Pietrain hybrids, imported from France and (Great White x Landrace x Pietrain) x Pietrain, imported from Romania, on the basis of which hybridization schemes were developed where the maternal form was Landrace x Great White in all variants. In all age periods, a higher specific feed consumption (3.1 kg feed/kg weight gain) was reported in the young pigs from the lot where the Duroc breed, known for its relatively higher fat accumulation in the adipose layer, was used for hybrid production. In the other hybrid types specific feed consumption ranged between 2.79 and 2.92kg. The genetic type of the boars was found to play a determining role on carcass and meat quality. According to production testing, backfat thickness in hybrids varied between 20.2 and 22.5 mm at a weight of 110-120 kg. The differences between tetraracial and triracial hybrids were 1.3 mm. Experimental data confirm the viability of using hybrid boars according to consumer requirements and the specifications of the final product delivered for processing.
Lucrarea prezintă rezultatele experimentale privind influența tipurilor genetice de vieri asupra calităților productive și consumului specific de furaje la hibrizi, precum și modificările acestuia pe parcursul procesului de creștere și îngrășare, odată cu avansarea în vârstă a suinelor. Studiul a avut ca obiect diferite tipuri genetice de vieri: rase pure Pietrain și Duroc, precum și hibrizi Duroc x Pietrain importați din Franța și (Marele Alb x Landrace x Pietrain) x Pietrain importați din România. Pe baza acestora au fost elaborate scheme de hibridare, în care forma maternă a fost Landrace x Marele Alb în toate variantele. În toate perioadele de vârstă, un consum specific de furaje mai ridicat (3,1 kg furaj/kg spor) a fost semnalat la tineretul suin din lotul, în care pentru producerea hibrizilor a fost utilizată rasa Duroc, cunoscută pentru acumulările relativ mai mari de grăsime în stratul adipos. În celelalte tipuri de hibrizi consumul specific de furaje s-a situat între 2,79 și 2,92 kg. S-a constatat că tipul genetic al vierilor are un rol determinant în formarea calității carcaselor și a producției de carne. Conform testărilor de producție, grosimea stratului de slănină la spinare la hibrizi a variat între 20,2 și 22,5 mm la o greutate de 110-120 kg. Diferențele între hibrizii tetrarasiali și trirasiali au fost de 1,3 mm. Datele experimentale confirmă viabilitatea utilizării vierilor hibrizi în funcție de cerințele consumatorilor și specificațiile produsului final destinat procesării
SURSE DE ALIMENTE NOI PE PIAŢA AUTOHTONĂ
Full text linkIn this study we aimed to determine the qualitative differences between buffalo milk and cow milk and to carry out a sociological survey to accumulate information on the consumption of buffalo milk and its derivatives. Milk obtained from cows and buffaloes, which are kept under the same conditions in a livestock unit in the Republic of Moldova, served as research material. Milk quality analyses, carried out by standard laboratory methods, revealed that buffalo milk has a much higher fat (9.50%) and protein (7.18%) content than cow milk (4.24% and 3.76% respectively). The content of lactose, mineral salts and dry matter in buffalo milk is also higher than in cow milk. Therefore, the nutritional value of buffalo milk is higher in all parameters. The sociological survey revealed that: most respondents prefer to consume cow milk; their don’t know buffalo milk products and neither do local producers. Among those who consume buffalo milk products, they mentioned Buffalo Mozzarella cheese in the first place, followed by yogurt, semi-hard cheese and drinking milk. For a successful market launch of buffalo milk products, we recommend producers to carry out promotion campaigns and tasting events. Through this, buffalo milk products will be visible to consumers, and local consumers in turn will be more receptive

Full text linkThe article presents the results of research conducted in 2022–2024 on the productivity and agroecological adaptability of new genotypes of winter soft wheat in various agro-climatic zones of Moldova. It was established that the grain yield of winter wheat varied from 7.82 t/ha in the northern zone to 3.78 t/ha in the southern zone. The most favorable conditions for winter wheat were observed in 2024 (northern zone), where the average grain yield was 8.16 t/ha, and for the central and southern zones in 2023, with yields of 8.90 t/ha and 5.28 t/ha, respectively. The highest-yielding genotypes were SBM (8.75 t/ha) and Kuyalnik (8.51 t/ha) in the northern zone; GTM (7.74 t/ha) and PIS (7.42 t/ha) in the central zone; and Kuyalnik (4.19 t/ha) and AIM (3.92 t/ha) in the southern zone. A high degree of agroecological adaptability to the conditions of the northern zone was shown by the genotypes SBM, TTM, AIM, PIM, OTM, and PZM; to the conditions of the central zone by SBM and GTM; and to the southern zone by PIM, MOM, and PZM. For the conditions of the republic, the control variety Kuyalnik and the GTM genotype demonstrated high agroecological adaptability. Half (50%) of the genotypes showed low adaptability to the conditions of Moldova.

Наиболее благоприятные условия для озимой пшеницы сложились в 2024 году (северная зона), где средняя урожайность зерна составила 8,16 т/га, для центральной и южной зон 2023 году, урожай составил 8,90 т/га и 5,28 т/га. Наиболее урожайными были генотипы в северной зоне СБМ (8,75 т/га) и Куяльник (8,51 т/га); в центральной зоне – ГТМ (7,74 т/га) и ПИС (7,42 т/га) и в южной зоне Куяльник (4,19 т/га) и АИМ (3,92 т/га). Высокую степень агроэкологической адаптивности к условиям северной зоны проявили генотипы СБМ, ТТМ, АИМ, ПИМ, ОТМ и ПЗМ, к условиям центральной зоне СБМ, ГТМ и южной зоны ПИМ, МОМ и ПЗМ. Для условий республики высокую агроэкологическую адаптивность проявили контрольный сорт Куяльник и генотип ГТМ. У половины (50%) генотипов отмечается низкая адаптивность к условиям Молдовы
IMPLEMENTATION OF INDUCTIVE PROCESSES IN GENERAL-PURPOSE EQUIPMENT TO ENHANCE HEAT TRANSFER PROCEDURES
Full text linkThe paper explores the energy efficiency of general-purpose installations, particularly the equipment used in espresso coffee production, and the unique functions of hydraulic systems. By applying eco-design principles and innovative, efficient solutions, the negative impact on the environment can be significantly reduced, transforming citizens into eco-consumers. The study aimed to explore ways to decrease energy consumption in hydraulic systems of standard installations, particularly in heat transfer processes in solids and liquids, which account for up to 97% of energy consumption in such installations. An innovative solution is presented that converts electric energy into heat in liquids using inductive heat transfer. The instant heating inductive boiler, based on inductive heat transfer phenomena, eliminates the convective and conductive heat transfer losses associated with the operation of the boiler with the resistive heating element. The design methodology for dimensioning this type of equipment is provided, and the simulation model for necessary verifications in MatLab Simscape is created. With its practical benefits, the new inductive boiler reduces the preheating period to 7.5 s compared to the 90 s of systems with resistive heating elements, thereby eliminating the need to keep the coffee machine at operating temperatures during breaks and providing a reliable solution for energy efficiency
THE IMPACT OF STORAGE CONDITIONS ON THE MICROBIOLOGICAL AND ORGANOLEPTIC QUALITY OF COOKED RICE
Full text linkCooked rice, owing to its high moisture content and rich nutritional profile, is particularly prone to microbiological contamination, especially under suboptimal storage conditions. This study investigated the effects of three distinct storage regimes—room temperature, refrigeration, and freezing—on the microbiological and organoleptic quality of cooked rice, with the objective of identifying safe consumption windows and minimizing quality degradation. Microbiological assessments were carried out in accordance with relevant ISO standards, while sensory evaluation was performed using a descriptive scoring method by a trained panel. The findings revealed that rice stored at room temperature became microbiologically unsafe after 24 hours. In contrast, refrigeration maintained microbiological safety up to day five, and freezing preserved overall stability for up to three months. However, sensory quality deteriorated progressively under all conditions, with the most pronounced alterations observed in samples frozen for over 90 days. These results underscore the critical role of appropriate storage conditions in ensuring food safety and preserving sensory attributes. While the study does not propose technological innovations, it provides a practical framework by integrating microbiological and sensory evaluations into a reproducible model applicable in both educational and professional settings
