In this paper we investigate the impact of delayed tax revenues on the fiscal policy outcomes. Choosing the delay as a bi-furcation parameter we study the direction and the stability of the bifurcating periodic solutions. With respect to the delay we show when the system is stable. Some numerical examples are finally given for justifying the theoretical results.

In two-parameter systems two symmetry breaking bi-furcation points of diierent types coalesce generically within one point. This causes secondary bifurcation points to exist. The aim of this paper is to understand this phenomenon with group theory and the innerconnectivity of irreducible representations of super-group and subgroups. Colored pictures of examples are included.

AIM The purpose of this study was to compare the clinical and subjective oral health indicators of type 2 diabetic patients (T2DM) with age and gender matched non-diabetic controls. A second aim was to identify clinical and subjective oral health indicators that discriminate between well-controlled and poorly controlled T2DM patients as well as between patients with long and short duration of t...

OBJECTIVES To explore the diagnostic values of digital intraoral radiography and cone beam CT (CBCT) in the determination of periodontal bone loss, infrabony craters and furcation involvements. METHODS Accuracy assessment of the imaging modalities was conducted through bone level measurements, infrabony crater and furcation involvement classifications. For CBCT, images were obtained at 120 kV...

Introduction. The aim of this work was to check the average thickness dentinal wall mesio-buccal root first lower molar using CBCT axial sections intact teeth. Material and method. In cross-sectional study, 100 images mandibular molars from Promax 3Dent radiology center in Banja Luka, Bosnia Herzegovina were evaluated. A Planmeca Promax3D Max apparatus (Planmeca, Helsinki, Finland) used, with a...

One of"the main conditions for the development of successful NLP applications is the usability of the syntactic formalisms adopted and the degree to which they facilitate syntax-semantics integration. TAG+ formalisms show a real potential for NLP applications, due to their linguistic descriptive capabilities. However, both the standard formalisms and parsing strategies are often quite complex a...

This case report presents an uncommon case of maxillary molar with two palatal root canals and an enamel pearl in the furcation area. The article discusses root canal complexities of maxillary second molars as well as possibility of coexisting anomalies in the region that makes radiographic interpretation difficult and compromises the success of endodontic treatment.

OBJECTIVE The aim of this controlled clinical trial was to evaluate the effect of topically applied povidone-iodine (PVP-I) used as an adjunct to non-surgical treatment of interproximal class II furcation involvements. MATERIAL AND METHODS Thirty-two patients presenting at least one interproximal class II furcation involvement that bled on probing with probing pocket depth (PPD) ≥ 5 mm were r...

The aim of this study was to evaluate the remaining dentine/cementum thickness using Gates-Glidden burs in serial and crown-down sequences and to observe which of the two sequences is the safest for preparing mesial roots of molars. Thirty-six left and right human mandibular first molars were selected. Standard access cavities were made and initially explored with Flexofiles sizes 10 and 15 unt...
