The Situation of Investment Projects for Modernization of Agricultural Holdings in Moldova Before and After Romania’s Accession to the European Union
The purpose of this article is to present the situation of EU funds absorption for modernization the agricultural holdings in Moldova, geographical region considered to be among the poorest in Romania. After 1989, the essential changes in the land structures ownership on the replacement the old structures land ownership of socialist economy with private property, have profoundly marked the Romanian rural space and the food trade balance of Romania suffered a continuing deterioration. The funding based on projects implemented once the SAPARD pre-accession funds, has provided many perspectives Romanian farmers, especially by increasing the budget for investments in the field. This approach shows that the economic performance of representative agricultural holdings in Moldova has evolved positively, but differently across the region
Plăcii bacteriene evaluarea rolului în evoluția leziunii gingivale
Background. Recent reserch designates the bacterial plaque as a well organized system of
microorganisms, which can be considered biofilm. Favoring factors cause the accumulation of bacterial
plaque which that triggers the development of gingivitis. Removal of bacterial plaque is a crucial step
for treatment. Objective of the study. Evaluation the stages of bacterial plaque formation, analysis of
the microflora in the plaque and determination of hers role in the development of gingival
inflammation. Material and Methods. The study included 25 patients. 17 patients (68%) with chronic
gingivitis and 8 healthy patients (32%) were examined, including 16 men (64%) and 9 (36%) women.
To perform the work, the clinical examination of the patients was performed (the indices OHI-S, PMA,
PBI were used), paraclinical and laboratory methods ( gram staining, cultivation on the culture of blood
agar). Results. In the study of the intensity of the inflammatory process of gingivitis, the PMA index
was used and a grade I gingivitis was determined in 18 % of patients, grade II 70% and grade III in 11%
of patients. In the smears taken from healthy patients, practically no microorganisms were detected. In
smears of patients affected with gingivitis were found gram-positive cocci, bacillus and leptotrichia. In
patients with moderate chronic gingivitis, gram-positive cocci predominated in a smaller number and
inflammatory elements. And in the smears collected from patients with severe chronic gingivitis were
gram-negative cocci, spirillum and inflammatory elements. Conclusion. Chronic gingivitis is an
inflammation of microbial cause, prevalent gram-negative. Depending on the amount and
aggressiveness of the bacteria in the plaque, gingival inflammation of different degrees can be installed:
mild,medium or severe.
Introducere. Cercetările recente desemnează placa bacteriană drept un sistem organizat de
microorganisme ce poate fi considerat biofilm. Factorii favorizanți determină acumularea plăcii
bacteriene care declașează dezvoltarea gingivitelor. Îndepărtarea plăcii constituie o etapă primordială
pentru tratament. Scopul lucrării. Evaluarea etapelor de formare a plăcii bacteriene, analiza microflorei
din componența plăcii și determinarea rolului ei în dezvoltarea inflamației gingivale. Material și
Metode. În studiul dat au fost incluși 25 de pacienți. Au fost examinați 17 pacienți (68%) cu gingivită
cronică și 8 pacienți (32%) sănătoși, dintre care 16 bărbați (64%) și 9 femei (36%). Pentru realizarea
lucrării s-a efectuat examenul clinic al pacienților (s-au utilizat indicii OHI-S, PMA, PBI), paraclinic și
metode de laborator (colorația gram, cultivarea pe mediul de cultură geloză-sânge). Rezultate. În cadrul
studiului intensității procesului inflamator al gingivitei s-a folosit indicele PMA și s-a determinat o
gingivită de gradul I-la 18% din pacienți, de gradul II-70% și de gradul III-la 11% pacienți. În frotiurile
prelevate de la pacienții sănătoși, practic nu au fost depistate microorganisme. În frotiurile colectate de
la pacienții afectați de gingivită cronică ușoară s-au depistat coci gram pozitivi, bacili, leptotrihii. În
cazul pacienților cu gingivită cronică medie predominau coci gram pozitivi într-un număr mai mic și
elemente inflamatorii. Iar în frotiurile colectate de la pacienții cu gingivită cronică gravă erau coci gram
negativi, spirili și elemente inflamatorii. Concluzii. Gingivita cronică este o inflamație de cauză
microbiană, prevalent gram-negativă. În dependență de cantitatea și agresivitatea bacteriilor din placă
poate fi instalată inflamația gingivală de diferit grad: ușor, mediu sau grav
Multi-Task Hypergraphs for Semi-supervised Learning using Earth Observations
There are many ways of interpreting the world and they are highly
interdependent. We exploit such complex dependencies and introduce a powerful
multi-task hypergraph, in which every node is a task and different paths
through the hypergraph reaching a given task become unsupervised teachers, by
forming ensembles that learn to generate reliable pseudolabels for that task.
Each hyperedge is part of an ensemble teacher for a given task and it is also a
student of the self-supervised hypergraph system. We apply our model to one of
the most important problems of our times, that of Earth Observation, which is
highly multi-task and it often suffers from missing ground-truth data. By
performing extensive experiments on the NASA NEO Dataset, spanning a period of
22 years, we demonstrate the value of our multi-task semi-supervised approach,
by consistent improvements over strong baselines and recent work. We also show
that the hypergraph can adapt unsupervised to gradual data distribution shifts
and reliably recover, through its multi-task self-supervision process, the
missing data for several observational layers for up to seven years.Comment: Accepted in ICCV 2023 Workshop
