Signs Are Taken for Wonders

Solomon Marcus was a Romanian scientist, whose fields of research span mathematical analysis, theoretical computer science, measure theory and general topology, linguistics, history and philosophy of mathematics, poetics, semiotics and applications of mathematics social science etc. From the very beginning of his career, Marcus showed a deep interest in analyzing the complex relationships between literature and science (mathematics), trying to identify those arguments which plead for what might be called “the unity of knowledge”. In his book on mathematical poetics the scientist has demonstrated that poetry and mathematics are both routes towards self-knowledge (as well as modalities of creating ideal objects). Moreover, his work as a whole underscores the increasing importance of aesthetics in the field of “hard” sciences. This article will focus on those strategies used by Marcus in his essays as neutralisers of the tensions between self-reading and world-reading.     &nbsp

Ion Vianu’s Autobiographical Account.

Ion Vianu (b.1934, Bucarest), Romanian psychiatrist and writer, son of a famous professor of comparative literature (Tudor Vianu), becomes recognized also for his positions against the communist authorities’ attempt of using psychiatry as a political weapon. In 1977 he chooses the path of exile, continuing his psychiatric research and practice in the Western world (Switzerland). Starting from the assumption that our scholar represents a paradigmatic example of what may be called an “in-between” identity, this paper intends to analyse the image(s) that the narrator gives of himself through a discourse which continuously tries to harmonize memory and forgetfulness, testimony and evidence, authenticity and rhetorical devices

The Conservation Measures of NATURA 2000 "Someșul Rece" Site Management Plan

Natura 2000 is a European network of protected natural areas including a significant number of natural habitats and wild species for the interest of comunnity. Natura 2000 ROSCI 0233 "Someșul Rece"  Site is situated in the south-western county of Cluj, on the administrative territory of Măguri-Răcătău and Ierii Valley. It has an area of 8529 ha and is a framed area of the Apuseni Mountains Alpine bioregions. The site preserves the following natural habitats: Rough mountain beech forests Asperulo-Fagetum, beech forests of Luzulo-Fagetum, forests acidophilous Picea Abies mountain region and protect important species and active fish fauna, flora and fauna of the Apuseni Mountains. It is also home for several species (mammals, amphibians, fish and beetles) like: lynx, wolf or otter. The conservation measures of Natura 2000 Somesul Rece Site, elaborated in order to protect the habitats and the species are part of the management plan. These measures were developed in close connection with the conservation status of habitats and species, but also taking into account the needs of local communities. These measures include: maintaining habitats in favorable conservation status; maintain the current habitat areas; preventing and combating poaching and overfishing;ensuring peace in areas of rock (for large mammals)

Uvjeti pridobivanja drva, osobitosti tržišta ili tržišno natjecanje: Rumunjska studija slučaja o kretanju ugovornih stopa za drvo na panju

A survey of timber harvesting operations and tendering prices was conducted in a representative forest region of Romania aiming to see to what extent the harvesting parameters of the sold harvesting stacks affect the tendering prices. Based on a sample of 1192 contracts, accounting for more than 20,000 harvested hectares and for more than 600,000 harvested cubic meters, descriptive statistics of harvesting conditions and tendering prices were computed and prediction models of tendering prices as a function of harvesting conditions were estimated. Harvesting factors such as the felling type, sold volume, removal intensity, tree size and pruning condition, slope and extraction distance had rather a low effect on the initial (adj. R2 = 0.20) and final tendering prices (adj. R2 = 0.17) showing that the remaining variability could be related to other factors. No obvious relations were found between the variation of harvesting factors and the variation of the difference in price paid by the contractors to buy the wood. As a consequence, a more detailed price analysis was conducted to see to what extent prices can be explained by the demand and supply evolution. Although the evolution of the prices and negotiated quantities may be considered confusing in the context of a normal market supply and demand, the analysis revealed that the stumpage market demand increase during analyzed years and there was a bigger demand for conifers species. The results of this study could be of help for both, the forest management and harvesting contractors in shaping and conducting their businesses. In addition, the study gives detailed statistics on the forest operations practices and conditions under the Romanian forestry, being of help for comparisons with other regions.U radu se istražuje povezanost postupaka pridobivanja drva i kretanja natječajnih cijena drva na panju. Istraživanje je provedeno na uzorku koji obuhvaća jednu šumsku regiju u Rumunjskoj, a cilj je bio utvrditi u kojoj mjeri pokazatelji pridobivanja prodanog drva utječu na natječajne cijene. Korišteni podaci Regionalne uprave šuma Baia Mare (RFA Baia Mare), Maramureş (slika 1), koja se sastoji od 13 šumarija, čine ugovore o sječi kroz tri godine gospodarenja (2012–2014). Autori smatraju da se navedeni podaci mogu smatrati reprezentativnim za rumunjske uvjete te mogu poslužiti kao ogledni primjer za svrhu istraživanja u ovoj studiji. Na temelju uzorka od 1192 potpisana ugovora, koji su obuhvaćali više od 20.000 ha sječne površine i više od 600.000 m3 užite drvne zalihe, na temelju deskriptivne statistike, dobiveni su modeli predviđanja budućih natječajnih cijena, ovisno o raznovrsnosti uvjeta pri pridobivanju drva. Značajke sustava pridobivanja drva kao što su: 1. vrsta sječe, 2. veličina sječine, 3. sječna gustoća, 4. dimenzije stabla, 5. nagib terena i 6. srednja udaljenost privlačenja drva, imali su prilično slab učinak na iznose natječajnih (početnih) (R2 = 0,20) i prodajnih (ostvarenih) cijena (R2 = 0,17), što pokazuje da se preostala varijabilnost cijena može odnositi i na druge čimbenike. Nije bilo jasno izraženih odnosa između odstupanja pokazatelja u sustavu pridobivanja drva i razlika u cijeni koju su ponuđači plaćali za kupnju drva na panju. Stoga je provedena detaljnija analiza cijena kako bi se vidjelo do koje se mjere cijene mogu objasniti promjenama u odnosu na ponudu i potražnju. Analiza je pokazala da je u razdoblju istraživanja došlo do povećanja potražnje drva na panju, istodobno i uz veću potražnju za vrstama četinjača. Rezultati ove studije mogli bi pomoći šumovlasnicima/šumoposjednicima pri gospodarenju šumama, ali i privatnim poduzetnicima u šumarstvu prilikom planiranja i vođenja njihovog poslovanja

USE OF SEXUAL PHEROMONES FOR MONITORING THE POPULATION OF THE PEST DELIA ANTIQUA (onion fly)

There were synthesized and tested: 2 variants for the Delia antiqua pheromone. The attack produced by the onion fly larvae in the onion culture was below 2%. In the climatic conditions of the year 2019, adults from generation 1 were captured in June, decades 1 and 2. The pheromonal variant V1 V1 - D (dipropyl disulfide) captured a greater number of adults, 57, 1%, compared to the control V2 - E (2 ø ethanol). - 42.9% of the total captured. Comparative study of the experiments carried out, setting up, experiments and testing of variants

Rolul potenţialului evocat, obţinut prin stimulare magnetică, în explorarea măduvei spinării

Analiza stării funcţionale a căilor motorii de la nivelul măduvei spinării este foarte importantă pentru neurologia clinică. Datorită poziţiei sale anatomice, măduva este difi cil de investigat prin metode neurofi ziologice uzuale. Metodele actuale de neurovizualizare nu permit întotdeauna obţinerea unei corelaţii clare între leziunile aparente imagistic și cauza dezvoltării simptomatologiei neurologice. Obiectivarea unei disfuncţii, ca și diferenţierea între afectarea măduvei sau a structurilor periferice (ca rezultat al iritaţiei, traumatizării sau compresiunii), poate fi importantă în diagnostic și în alegerea terapiei. Informaţiile structurale furnizate de metodele imagistice nu sunt sufi ciente pentru aprecierea impactului funcţional. Stimularea magnetică transcraniană este o metodă neinvazivă și nedureroasă, care asigură investigarea tractului corticospinal la orice nivel, aducând informaţii privind statusul funcţional al acestuia. Printre bolile sistemului nervos pentru care metoda stimulării magnetice este utilă se numără modifi cările degenerative (mielopatii), bolile reumatologice infl amatorii (de ex., spondilartrita anchilozantă), traumatismele coloanei vertebrale sau măduvei, demielinizările etc

Neonates from multiple pregnancies – complications, outcome

Spitalul Clinic de Obstetrică şi Ginecologie ”Cuza-Vodă”, Centrul Regional de Terapie Intensivă Neonatală, Iaşi, România, Universitatea de Medicină şi Farmacie ”Grigore T. Popa”, Iaşi, RomâniaIntroducere: sarcina multiplă reprezintă una din principalele cauze de prematuritate şi complicaţii secundare, mai ales în contextul creşterii numărului de sarcini obţinute prin fertilizare in vitro (FIV) şi al progresului managementului nou-născutului cu risc crescut. Secundar se constată o rată mai mare a supravieţuirii, dar şi a morbidităţii cu potenţiale sechele pe termen lung. Obiective: evaluarea incidenţei naşterilor din sarcină multiplă, a mortalităţii şi principalelor categorii de morbiditate a acestei categorii de nou-născuţi. Material şi metodă: am efectuat un studiu retrospectiv observaţional asupra nou-născuţilor proveniţi din sarcini multiple, îngrijiţi în centrul nostru în perioada 2015-2017. Am evaluat următorii parametri: modul de obţinere a sarcinii, modul naşterii, vârsta de gestaţie, greutatea la naştere, resuscitarea la naştere, complicaţii în timpul spitalizării, modalităţile terapeutice, durata de spitalizare. Rezultate: din 19550 nou-născuţi în Maternitatea ”Cuza-Vodă”, 609 cazuri au provenit din 296 sarcini multiple, cu o incidenţă totală de 1,51% şi o vârstă gestaţională de 34,5 săptămâni. Dintre acestea, 280 sarcini au fost gemelare (94,59%), 15 sarcini triple (5,07%) şi 1 sarcină cvadruplă (0,34%). 40 sarcini au fost induse artificial prin FIV (13,51%). Nu se constată diferenţă statistică între sarcinile gemelare sau cu tripleţi în privinţa modului de concepţie – natural sau prin FIV (p = 0.861). FIV se asociază cu o vârstă gestaţională mai crescută (p = 0.0248), cu naşterea prin cezariană (p = 0.0289) şi apnee de prematuritate (p=0.034). Nu se observă diferenţe statistic semnificative în privinţa nevoii administrării de surfactant, numărului de zile de spitalizare sau nevoii de ventilaţie mecanică. Nou-născuţii de rang 3 şi 4 se asociază cu un necesar crescut de reanimare la naştere (p=0.0313), ventilaţie mecanică (p=0.013), sindrom de detresă respiratorie (p=0.014), apnee de prematuritate (p=0.0255), infecţie (p=0.0057) şi tulburări metabolice (p=0.0004). Nou-născuţii proveniţi din sarcină obţinută natural prezintă o rată mai crescută a mortalităţii (p=0.034). Concluzii: în studiul nostru, sarcinile multiple obţinute prin FIV au beneficiat de urmărire prenatală mai riguroasă, în contextul aceleiaşi îngrijiri postnatale ca şi a celor obţinute natural. Sarcinile multiple sunt sarcini cu risc neonatal crescut şi necesită o mai bună depistare şi monitorizare prenatală pentru a fi îndrumate spre centre cu posibilităţi de îngrijire adecvate pentru nou-născuţi.Background: Multiple pregnancies became one of the leading causes of prematurity and subsequent complications, mainly because of the increasing rate of in vitro fertilization (IVF) procedures and fast progress in the management of high-risk neonates. The effect is a higher rate of survival, but also of morbidity with long-term consequences. Objective: To evaluate the incidence of births from multiple pregnancies, mortality, and main morbidity categories in this category of infants. Material and methods: we performed an observational retrospective study on infants coming from multiple pregnancies, born in our hospital over three years (2015-2017). We assessed the following parameters: type of conception, mode of birth, gestational age, birth weight, resuscitation in the delivery room, therapeutic maneuvers, length of hospital stay. Results: Out of a total of 19550 newborns, 609 infants resulted from 296 multiple pregnancies, with a total incidence of 1.51% and a mean gestational age of 34.5 weeks. Among them 280 were twins (94.59%), 15 were triplets (5.07%) and 1 were quadruplets (0.34%). 40 pregnancies resulted from IVF (13.51%). There is no statistical difference between the number of twin vs triplets pregnancies regarding the type of conception: natural vs IVF (p = 0.861). IVF is associated with higher gestational age (p = 0.0248), Caesarean section (p = 0.0289) and apnea of prematurity (p=0.034) comparing with natural multiple pregnancies that presented higher mortality rate (p=0.034). No significant difference regarding surfactant administration, days of hospitalization, and need for mechanical ventilation were observed. Range 3 and 4 newborns were associated with higher need of resuscitation at birth (p=0.0313), mechanical ventilation (p=0.013), respiratory distress syndrome (p=0.014), apnea of prematurity (p=0.0255), infection (p=0.0057) and metabolic dysfunction (p=0.0004). Conclusions: neonates from in vitro fertilization have better prenatal care, despite the same postnatal care as natural multiple gestations. Multiple pregnancies are of high risk for neonates and should be better diagnosed and referred to higher levels of neonatal care

The role of rehabilitation and anabolic treatment in severe os-teoporosis associated with significant vitamin D deficiency – case report

It is well known that vitamin D deficiency increases the risk of osteoporosis and that vertebral compressions fractures are a manifestation of osteoporosis. This paper presents the case of a patient with severe osteoporosis associated with vitamin D deficiency who developed over the course of two years multiple vertebral compression fractures. Method: We present the case of a 76-year-old caucasian female diagnosed with osteoporosis and significant vitamin D deficiency who was investigated for mechanical pain and functional deficit at the level of the spine and walking disorders. The patient was hospitalized in our Rehabilitation department twice. At the first hospitalization two years ago, the deficiency of vitamin D was found and the treatment was initiated. During the sec-ond hospitalization, biochemical and radiological investigations were per-formed to establish the diagnosis. Numerous vertebral compression fractures were dis-covered which were not re-vealed in the imaging investigations performed two years earli-er. She underwent symptomatic and appropriate medical rehabilitation treatment. Results and discussion: The evolution was fa-vorable after the hospitalization period, with a decrease in pain and functional deficit, as well as walking improvement. After endocrinological consultation it was decided to initiate therapy with Teriparatide which can decrease the risk of future fractures and reduce the back pain. Con-clusions: Adequate and prompt treatment of vitamin D deficiency and osteoporosis is very im-portant to avoid vertebral compression fractures or other complications of this disease. Physical and rehabilitation medicine also plays an important role in management of these patients
