Laceability properties in the image graph of Prism graphs

A connected graph G is termed Hamiltonian-t-laceable if there exists in it a Hamiltonian path between every pair of vertices u and v with the property d(u, v) = t, 1 ≤ t ≤ diam(G), where t is a positive integer. In this paper, we establish laceability properties in the image graph of Prism graph Im(Yn).Publisher's Versio

Assessment of Peri-Implant Marginal Bone Level in Single Crowns Supported by Short Dental Implants: A Cone Beam Computed Tomography (CBCT) study

BACKGROUND AND OBJECTIVES: The purpose of this study is to clinically assess and compare the peri-implant marginal bone level in single crowns supported by short dental implants for a period of 1 year at regular 3 months time interval. MATERIALS AND METHODS: 14 subjects in age range of 18-55 years, with at least one missing maxillary/ mandibular posterior tooth were selected and received 14 short dental implants. Clinical parameters namely the modified plaque index, gingival index, probing depth, implant mobility scale were recorded. The radiographic parameter, bone loss was measured at 4 sites namely mesial horizontal, mesial vertical, distal horizontal, distal vertical by using CBCT. All the parameters were recorded before and after implant placement and at 3 months interval till one year. CBCT analysis will be done at baseline, 3 months (the time of crown placement), 9 months (after crown placement) to assess the peri-implant marginal bone level changes around implants. RESULTS: The mean bone loss at the mesial horizontal site was 1.86 ± 0.32 mm, mesial vertical site was 1.73 ± 0.34 mm, distal horizontal site was 1.09 ± 0.45 mm, and distal vertical site was 0.81 ± 0.38 mm at 3 months. The mean bone loss at the mesial horizontal site was 1.81 ± 0.19 mm, mesial vertical site was 1.69 ± 0.27 mm, distal horizontal site was 1.06 ± 0.33 mm, and distal vertical site was 0.76 ± 0.29 mm at 12 months. The comparison of bone loss between 3 and 12 months at various sites (mesial horizontal, mesial vertical, distal horizontal, distal vertical) was done. The results showed significant differences (p≤ 0.05) for modified plaque index, gingival index, probing depth. The overall mean bone loss at 3 months was found to be 1.37 ± 0.57 mm. The overall mean bone loss at 12 months was found to be 1.33 ± 0.51 mm. The comparison of the overall mean bone loss at 3 months and 12 months was 1.37 ± 0.57 mm and 1.33 ± 0.51 mm respectively. CONCLUSION: With the limitation of the study, it was concluded that the characteristics of the implant surface may influence the survival rate of short dental implants with minimal peri- implant marginal bone loss

Stoichiometry control of sputtered CuCl thin films: Influence on ultraviolet emission properties

We demonstrate that the chemical composition of the sputtered CuCl thin films could be finely controlled by adjusting the bias to the substrate. The films deposited without any intentional bias were Cl rich (CuCl1+x), a bias of −22 V yielded stoichiometric CuCl, and a further increase in the negative bias resulted in Cl deficient films (CuCl1−x). The crystalline and optical properties were found to be associated with the chemical composition. Cl rich films showed a deep level green emission at around 515 nm in addition to ultraviolet (UV) excitonic emission. The stoichiometric films have higher optical quality, exhibiting a sharp UV emission at around 385 nm at room temperature, compared to nonstoichiometric samples. Visible luminescence related to deep level defects was not observed in the stoichiometric films. Changes in energy of the flux from the target and the subsequent ion bombardment on the substrate surface are correlated with the variations in chemical composition and their impact on the film microstructure and UV emission

Intuitionistic Hesitant Fuzzy UP (BCC)-Filters of UP (BCC)-Algebras

The concepts of intuitionistic hesitant fuzzy UP (BCC)-subalgebras, UP (BCC)-ideals, and UP (BCC)-filters of UP (BCC)-algebras are presented, some of their features are explained, and their extensions are demonstrated using the theory of hesitant fuzzy sets as a foundation. The necessary conditions for those intuitionistic hesitant fuzzy sets are provided and include their relation to their complement. The concept of prime and weakly prime of intuitionistic hesitant fuzzy sets was also introduced and studied. We also talk about the connections between intuitionistic hesitant fuzzy UP (BCC)-subalgebras (UP (BCC)-ideals, UP (BCC)-filters) and their level subsets. The homomorphic pre-images of intuitionistic hesitant fuzzy UP (BCC)-filters in UP (BCC)-algebras are also studied and some related properties are investigated

Derivations of Hilbert Algebras

In this paper, we introduce the notions of (l, r)-derivations, (r, l)-derivations, and derivations of Hilbert algebras and investigate some related properties. In addition, we define two subsets for a derivation d of a Hilbert algebra X, Ker d(X) and Fix d(X), and we also take a look at some of their characteristics

Synthesis, characterization, biological and catalytic activity of carboxymethyl chitosan schiff base metal complexes

The Schiff base of carboxymethyl chitosan/p-dimethylaminobenzaldehyde (CMC-SB), as well as its complexes with cobalt (CMC-SB-Co), nickel (CMC-SB-Ni), and zinc (CMC-SB-Zn), were synthesised and studied using FTIR, XRD, TGA, DSC, and SEM. Schiff base metal complex production has been verified by the FTIR and XRD data. According to the thermal studies, the CMC-SB Zinc combination has better thermal stability than other complexes. The material is porous and rough, and the SEM results show that it has several potential uses in the biological field. The zinc complexes have increased activity when it comes to catalysis. It has been determined by the MTT test and ALP activity that the synthesised sample is non-toxic, compatible, and has good antioxidant activity

Sorption studies of divalent ions onto ternary beads of alginate, chitosan and carboxymethyl cellulose

The potential of sodium alginate (AL)/ chitosan (CS)/ carboxymethyl cellulose (CMC) beads as an adsorbent for removing the divalent metal ions such as Cu (II) and Ni (II) ions from aqueous solution was assessed in the current work using a batch adsorption technique. FT-IR and XRD measurements were used to investigate the formation of the ternary beads. The percentage removal of metal ions was investigated in batch mode as a function of metal ion solution pH, initial metal ion concentration, adsorbent dosage, and contact time. The observed outcome shows that the best pH for removing both metal ions was reported to be 5.0. The incorporation of experimental data in theoretical modelling exhibits that the adsorption would be multilayer through pseudo-second order (R2 > 0.9) kinetics. The removal efficiency of ternary beads reveals that copper ions (Cmax = 203.69 mg/g) were removed better than nickel ions (Cmax = 194.05 mg/g)

Sorption studies on the removal of copper onto biopolymer derivative: chitosan-g-maliec anhydride-g-ethylene dimethacrylate

The current work suggests employing an unique Chitosan-g-Maleic anhydride-g-ethylene dimethacrylate copolymer to remove the harmful heavy element copper. By adjusting variables like the concentration of the monomer, the concentration of the initiator, and the temperature during the chain polymerization reaction, the graft copolymer was developed. The copolymer obtained at the optimum condition was picked out to study its adsorption property towards Cu2+ ions. The adsorption factors, such as the amount of adsorbent, contact time, pH, and initial concentration of the metal solution, which affect the adsorption process, were looked at using the batch adsorption mode. Freundlich and Langmuir isotherm models were applied to analyse the equilibrium adsorption
