Types of words in the Serbian language occuring only in the plural form ; Склоняемые части речи сербского языка употребляющиеся только во множественном числе

Предмет овог истраживања јесу именске речи које се јављају само у множини у српском језику. То су све оне лексеме којима је основни облик множински и које тим обликом означавају и једнину и множину. Будући да им недостаје једна реализација категорије броја, сматрају се за дефективне облике. У литератури се за овакве речи најчешће употребљава термин плуралија тантум (pluralia tantum), али се он углавном односи на именице...The subject of this research are the types of nouns which only occur in plural form. These are all those lexemes whose fundamental form is plural and as such denotes both the singularity and the plural form of said noun. Since they lack the realisation of a number category, they are considered defective. In literature these words are most commonly referred to as pluralia tantum. From the dictionaries of contemporary Serbian language (Dictionary of Serbo-Croatian Literary Language and Vernaculars of the Serbian Academy of Sciences and Arts, Dictionary of Serbo-Croatian Literary Language in six volumes published by Matica srpska, Dictionary of the Serbian Language, Reverse Dictionary of the Serbian Language) all lexemes designated with a qualifier mn. or a lexicographic constant which refers to dominant plural use of the lexeme (obično(u) mn., često(u) mn., najčešće(u) mn., and others) were excerpted. In an effort to fully describe this category of words, words from the electronic corpus of the Serbian language, examples from the internet, as well as various foreign words were used to build the corpus group..

Peripheral giant cell granuloma: Case report

Peripheral giant cell granuloma (PGCG) or 'epulis gigantocelularis' is the most common oral lesion that originates from giant cells. It typically manifests in the form of soft tissue tumor purple-red or red-watery color consisting of multinuclear giant cells in the mononuclear stroma and extravascular erythrocytes. This lesion is not considered true neoplasm, rather reactive lesion stimulated by local irritation and trauma. However, the cause is not known with certainty. This paper presents a 13-year-old boy with a large lesion in the region of right maxillary canine that was retained in jaw despite favorable vertical position and available space to accommodate in the dental arch. The lesion was completely removed under local anesthesia and histopathological findings confirmed the diagnosis of PGCG. Postoperative period went without complications. After four months additional surgical procedure was needed due to the recurrence, which after tooth naturally erupted and positioned in the dental arch

Redefinisanje prostora savremenog konteksta grada - kretanje i percepcija kao vidovi dostupnosti

The aim of this paper is research of the potential and redefining of space of the contemporary urban context, by recognizing movement and senses as principles of accessibility and affirmation of the neglected values of the city in regard to design aspects. A global context of networking transforms a modern city into processes of busy lifestyle, which neglect diversity and senses. Flows and networking, as the carriers of this context, despite their goal to create a connection between the global and the local and establish equality of all users, generate local separation and segregation, eliminating specific local traits and individual needs, thus neglecting individual units of space, social groups and subjects. The consequences of the city developing in this way are spatial fragments not connected to a network and not defined, and on the other hand neglected in a way that leads to specific environmental and sensory values, which under contemporary conditions propagate subjectivity, different impressions and effects. This spatial potential becomes recognized, distinguished and accessible through design methods and principles of inclusive design. The paper uses the methodology of the subject Access to All, a part of the Master studies programme at the Faculty of Architecture, as well as students' research on the topic of inclusion and equal accessibility of the city's potential through projects and design.Cilj rada je istraživanje potencijala i redefinisanje prostora savremenog urbanog konteksta, prepoznajući kretanje i čulnost kao principe dostupnosti i afirmacije zapostavljenih vrednosti grada kroz projektantske aspekte. Globalni kontekst umreženosti savremeni grad transformiše u procese ubrzanog načina života, kojima se zapostavljaju raznovrsnost i čulnost. Tokovi i umrežavanje, kao nosioci takvog konteksta, nasuprot cilju da ostvare vezu globalnog i lokalnog i uspostave jednakost svih korisnika, sa druge strane stvaraju lokalne separacije i segregacije, eliminišući lokalne specifičnosti, pojedinačne potrebe i tako zapostavljajući pojedine prostore, društvene grupe i subjekte. Posledica ovakvog razvoja grada su neumreženi i nedefinisani prostorni fragmenti, čija je zapostavljenost sa druge strane nosilac specifičnih ambijentalnih i čulnih vrednosti, koje u savremenim okolnostima afirmišu subjektivnost, drugačije doživljaje i efekte. Ovi prostorni potencijali postaju prepoznati, naglašeni i dostupni putem projektantskih metoda i principa inkluzivnog dizajna. Rad se oslanja na metodologiju predmeta Dostupnost za sve na programu Master studija Arhitektonskog fakulteta, kao i na studentska istraživanja na temu inkluzije i jednake dostupnosti potencijala grada kroz projektovanje i dizajn

Assessment of deciduous dentition in 6-10 year old school children

Introduction. The emergence of deciduous teeth in the mouth of a child usually brings a joy to every parent. However, after ”short-time euphoria” deciduous teeth, in most cases, become the cause of pain, swelling, infection and further complications. The aim of this study was to assess the status of deciduous teeth in school children. Material and Methods. The study included children age 6-10 years from four cities in Republika Srpska. All respondents were divided in two groups: Group I included those who voluntarily came to be examined at the dental clinic and the Group II-those who were randomly chosen in schools. The examination was performed using dental mirror and probe. Caries verification was carried out by Klein-Palmer system, dmft (d - decay; m - missing; f - filling), and its related indices: Person caries index (pci) and Average caries index (aci). In addition, a survey was conducted. Results. A total number of 228 respondents were examined. Total pci was 96.1%. On average, each child had aci= 4.17 while 10.52% of the children had fillings in primary teeth. None of the children had sealed fissures on deciduous teeth. Physical examination revealed that 12.2% of the children had submucous abscess in oral cavity. The survey revealed that 3% of children did not have a tooth brush. Conclusion. The prevalence of caries in primary teeth is high, despite the fact that the Health Insurance Fund in Republika Srpska covers full cost for complete restoration of teeth in children up to 15 years old. Responsibility for the low percentage of healthy and filled teeth is relying mostly on parents as well as the entire community that should provide development and availability of public health dental care in all areas

Sliding spin-density waves: studies of conduction noise, magnetic field dependence and Hall resistivity

We have studied the current-voltage characteristics of the (TMTSF)_2PF_6 in the spin density state (SDW), and in zero and finite external magnetic field. For the oscillating part of the nonlinear voltage response to the applied DC electric field, the fundamental frequency distribution (as a function of this field) and a nonlinear relation between the frequency and the SDW current reveal the growth of parallel conduction channels characterized by lower velocities and larger cross-sections. The number of fundamental frequencies, their amplitude and the level of low-frequency noise as well as the depinning behaviour provide a consistent indication of the sample inhomogeneities and associated local field variations, and might be well understood within the framework of the phase slippage model. The increase of the threshold electric field with the applied magnetic filed can be explained by the Bjeli-Maki theory, if the imperfect nesting is taken into account. Finally, the electric-field dependence of the Hall resistivity is consistent with the sliding mechanism of the SDW conduction

Sensitivity of OHCA recognition in the emergency dispatch center of Subotica

Introduction: Dispatch centre plays the key role, as the first link in the survival chain by recognizing an out-of-hospital cardiac arrest (OHCA), good triage and accordingly, by the adequate response time of the emergency medical team. The aim of the work: analysis of the sensitivity of sudden cardiac arrest calls received at dispatch centre by the dispatcher of the Emergency Medical Service Subotica. Method: Retrospective analysis of the call receiving protocols and comparison with the medical protocols of the Emergency Medical Service (EMS) Subotica, for the period from January 1st, 2016 till December 31st, 2016. Results: The total number of calls received for medical teams was 10,172,during 2016 in the EMS Subotica. In the observed period, 116 OHCA (1.14% of total calls) were confirmed by medical teams, on the field, while CPR was initiated in 110 cases (1,08% ). 68 cases of OHCA were recognized at receiving the calls by the dispatcher, that were issued as the first order of emergency, 48 OHCA were not recognized at calls, however, 16 (16/48) of the calls were issued as the first order of emergency, while the other 32 (32/48) were the second order of emergency. The Sensitivity of calls of recognizing OHCA was 58,62 - 71,41%. No results were obtained for specificity, due to the lack of data in the records. Conclusion : Dispatch centre is the most important link in the chain of care for critically ill patients. There is a need for a unique way of documenting data. Recognition of OHCA by the dispatcher should become a parameter of the measure for the quality of emergency medical assistance work

Unconventional spin density wave in Bechgaard salt (TMTSF)2NO3

Among many Bechgaard salts, TMTSF2NO3 exhibits very anomalous low temperature properties. Unlike conventional spin density wave (SDW), TMTSF2NO3 undergoes the SDW transition at \T_SDW\approx 9.5 K and the low temperature quasiparticle excitations are gapless. Also, it is known that TMTSF2NO3 does not exhibit superconductivity even under pressure, while FISDW is found in TMTSF2NO3 only for P=8.5 kbar and B>20 T. Here we shall show that both the angle dependent magnetoresistance data and the nonlinear Hall resistance of TMTSF2NO3 at ambient pressure are interpreted satisfactory in terms of unconventional spin density wave (USDW). Based on these facts, we propose a new phase diagram for Bechgaards salts.Comment: 4 pages, 4 figs, RevTe

Povećana telesna masa i oralno zdravlje dece

Backgraund/Aim. Increased body weight in childhood may have negative effects on many tissues and organs in the body. The aim of this study was to determine whether the state of oral health in children with increased body mass is different from the children with normal body weight. Methods. The study included 190 children, aged 6 to 15 years. Assessment of nutritional status of subjects was performed by the use of Body Mass, and the respondents were divided into a group of increased body weight children (IWC) and a group of normal body weight children (NWC). Hard dental tissue state of health was assessed by the decayed, missing and filled teeth (DMFT) index. The gingival health was assessed using gingival index (GI). Community Periodontal Index (CPI) was used for the assessment of periodontal tissue. The oral hygiene was assessed using the Simplified Debris (Plaque) Index Greene-Vermilion. Results. Average DMFT value in the IWC group was 5.01 ± 2.4, and in the NWC 4.43 ± 2.0; (p > 0.05). GI values in the IWC group was 0.64 ± 0.37, while in the NWC group it was 0.55 ± 0.35 (the difference was not statistically significant). Average CPI index values were 1.33 ± 0.49 in the IWC group and 0.77 ± 0.61 in the NWC group and statistically significant differences were observed concerning periodontal tissue state of health. The GV index values in the IWC group were 1.01 ± 0.49, and in the NWC group 0.89 ± 0.45; it was not statistically significant. Conclusion. Results of this research do not indicate that children with increased body weight have more affected teeth. However, they have a worse condition of periodontal tissue in comparison to normal weight children.Uvod/Cilj. Povećana telesna masa u dečijem uzrastu može negativno da utiče na mnoga tkiva i organe u organizmu čoveka. Cilj ove studije bio je da se ustanovi da li se stanje oralnog zdravlja dece sa povećanom telesnom masom razlikuje u odnosu na decu koja imaju normalnu telesnu masu. Metode. U studiju je bilo uključeno190 dece, uzrasta od 6 do 15 godina. Procena stepena uhranjenosti ispitanika izvršena je pomoću Indeksa telesne mase, a ispitanici su podeljeni u grupu dece sa povećanom telesnom masom i decu sa normalnom telesnom masom. Stanje zdravlja tvrdih zubnih tkiva ocenjeno je pomoću KEP indeksa (ukupan broj karoiznih, ekstrahovanih i plombiranih zuba). Stanje zdravlja gingive procenjeno je pomoću loe Gingivalnog indeksa (GI). Za procenu parodontalnih tkiva upotrebljen je Community Periodontal Index (CPI). Stanje oralne higijene utvđeno je uz pomoć Plak indeksa po Greene-Vermilion- u. Rezultati. U grupi djece sa povećanom telesnom masom prosečna vrednost indeksa KEP bila je 5,01 ± 2,4 a kod dece sa normalnom telesnom masom 4,43 ± 2,0; ova razlika nije bila statistički značajna. Vrednost GI u grupi gojazne dece bila je 0,64 ± 0,37, a u grupi dece sa normalnom telesnom masom 0,55 ± 0,35; ni ova razlika nije bila statistički značajna. Prosečne vrednosti CPI u grupi gojazne dece bila je 1,33 ± 0,49, a u grupi dece sa normalnom telesnom masom 0,77 ± 0,61 što je bilo statistički značajno (p lt 0.05). Vrednosti plak-indeksa nisu bile statistički značajno različitie u obe ispitivane grupe dece. Zaključak. Rezultati istraživanja ne ukazuju da deca sa povećanom telesnom masom imaju više obolelih zuba. Međutim, ona imaju teži stepen obolenja parodontalnih tkiva u odnosu na decu koja imaju normalnu telesnu masu

Molecular tools for utilization of mitochondrial diversity in faba bean (vicia faba)

We performed in silico PCR analyses utilizing complete mitochondrial (mtDNA) genome sequences of faba bean (Vicia faba) and two related species, Vigna angularis and Vigna radiata, currently available in GenBank, to infer whether 15 published universal primer pairs for amplification of all 14 cis-spliced introns in genes of NADH subunits (nad genes) are suitable for V. faba and related species. Then, we tested via PCR reactions whether seven out of 15 primer pairs would generate PCR products suitable for further manipulation in 16 genotypes of V. faba representing all botanical varieties of this species (major, minor, equina and subsp. paucijuga) of various levels of improvement (traditional and improved cultivars) originating from Europe, Africa, Asia and south America. We provide new PCR primers for amplification of nad1 intron 2/3 in V. faba, and demonstrate intraspecific variability in primary nucleotide sequences at this locus. Based on outcomes of both in silico predictions and PCR amplification, we report a set of PCR primers for amplification of five introns in nad genes that are promising molecular tools for future phylogeographic and other studies in this species for which unambiguous data on wild ancestors, centre of origin and domestication are lacking

Iron status among blood donors deferred due to low haemoglobin level

Uvod/Cilj. Određivanje nivoa hemoglobin (Hb) je rutinski deo selekcije dobrovoljnih davalaca krvi. Prethodno publikovane studije pokazale su da se nedostatak gvožđa javlja kod redovnih davalaca krvi. Cilj ove prospektivne studije je bio da se utvrdi status gvožđa kod davalaca kod kojih je pre davanja utvrđen nizak nivo Hb i da se proceni stepen korelacije kapilarnih metoda, sa referentnom metodom određivanja Hb iz venske krvi, kao i sa i nivoom feritina. Metode. U periodu od februara 2017. do decembra 2018. godine, bilo je uključeno 200 dobrovoljnih davalaca sa niskim nivoima Hb, starosne dobi 19-64 godine (medijana 39 godina). Hb je određivan primenom metode bakar sulfat, kapilarnom metodom "HemoCue", i iz venske krvi u sklopu određivanja kompletne krvne slike (KKS). Nivo feritina određivan je primenom turbodimetrijske metode. Rezultati. Nizak nivo feritina utvrđen je kod 42,7% muškaraca i 57,3% žena (p = 0,008). U odnosu na nivo feritina lt 12 mg/L, odnosno gt 50 mg/L, zabeležena je značajna razlika između polova (p = 0,023, odnosno p = 0,022). Poređenje vrednosti Hb dobijenih kapilarnim metodama u odnosu na referentne vrednosti Hb, određene iz KKS, pokazalo je da metoda s bakar sulfatom daje lažno niske vrednosti Hb kod 10,5% slučajeva (p lt 0,001). Vrednosti Hb dobijene metodom "HemoCue-a" značajno su korelirale sa vrednostima Hb iz KKS, dok korelacija između nivoa feritina i Hb, određenog pomoću obe kapilarne metode, nije uočena. Zaključak. Kod 51,5% naših davalaca krvi koji su vraćeni zbog niskih vrednosti Hb utvrđen je snižen nivo feritina. Na osnovu ovih rezultata neophodno je odrediti algoritam za detekciju nedostatka gvožđa, dok je kapilarna metoda (HemoCue) pogodnija metoda za testiranje Hb pre davanja krvi.Background/Aim. Haemoglobin (Hb) determination is a routine part of the blood donor selection process. Previously reported studies have revealed that iron deficiency is common in frequent donors. This prospective investigation was aimed at examining iron status among blood donors with low circulating Hb and evaluating correlation between Hb values determined by capillary methods and those obtained by reference method from venous blood count (BC), as well as ferritin level. Methods. Between February 2017 and December 2018, 200 consecutively recruited regular blood donors with low Hb, aged 19 to 64 years (median 39), were included. Hb level was determined using the copper sulphate method, the HemoCue capillary method, and also from venous blood within the complete blood count (CBC) test. Plasma ferritin was determined turbidimetrically. Results. In 42.7% of men and 57.3% of women, ferritin concentration was low (p = 0.008). The relative numbers of males and females, with levels lt 12 mg/L (p = 0.023) or gt 50 mg/L (p = 0.022), differed. Comparison of the values obtained with the capillary methods with reference Hb levels obtained from the CBC test showed that the copper sulphate procedure gave false fails in 10.5% of cases (p lt 0.001). Hb values from HemoCue were significantly correlated with Hb values from the CBC test, but no correlation was observed between ferritin levels and Hb levels determined by both capillary method. Conclusion. Low ferritin was observed in 51.5% of Serbian blood donors deferred due to low Hb. Based on our results, the determination of the algorithm in the iron deficiency detection is necessary, while the capillary method (HemoCue) represents a more convenient method for Hb testing prior to blood donation
