Background: Dental crowding, a common orthodontic issue, arises due to a mismatch between tooth size and jaw dimensions, significantly affecting dentofacial aesthetics. This study focused on maxillary anterior crowding (M x AC) to investigate its relationship with the tooth size and jaw dimensions.
Materials and Methods: This retrospective cross-sectional study included 80 participants divided into two groups: 40 with normal occlusion (control) and 40 with MxAC occlusion. Dental casts were prepared using alginate impressions and dental stones, and measurements were taken for mesiodistal dimensions, arch width, arch depth, overbite, overjet, and arch length discrepancy using a modified sliding caliper gauge. Differences between the two groups were compared using an independent t-test. Statistical significance was set at P < 0.05.
Results: Significant differences were observed in tooth dimensions and arch measurements between the M × AC and control groups (P< 0.001). The M × AC group had larger dental crowns (except for the first molar), smaller overjet, and greater arch length discrepancy. The control group exhibited larger arch widths in the first premolar, second premolar, and first molar positions, but not in the canine position (P=0.420). Additionally, the M x AC group had significantly smaller arch depths at the canine, first, and second premolar positions (P< 0.001). However, no significant difference was observed between the groups in dental arch depth at the first molar position (P=0.120).
Conclusion: The study found significant differences in tooth dimensions and dental arch measurements between the M × AC and control groups. The M × AC group had larger dental crowns (except for the first molar), less overjet, and greater arch length discrepancy. Arch widths for the premolars and the first molar were larger in the control group, while the M x AC group had smaller arch depths at the canine and premolar positions. These findings underscore the need for customized orthodontic treatment.

Published: January 2025

Cyanide solutions used in industry are harmful not only to humans but also to other living organisms. The development of low cost and simple in preparation electrodes for cyanide electrochemical destruction is an important requirement. Ti electrodes galvanostatically covered with a Pt layer of 120, 300 and 600 nm average thickness were chosen as the anodes for electrochemical oxidation of high concentration (0.1 M) cyanide solutions. The morphology and microstructure of Pt coatings were observed by using scanning electron microscopy (SEM) and X-ray diffraction (XRD) methods. It was found from XRD data that the average Pt crystallite size is equal to 9.3 ± 0.5 nm regardless of whether the electrode has been exploited for cyanide electrochemical destruction. Electrocatalytic activity of platinized Ti electrodes was tested by determining the current efficiencies of cyanide electrooxidation that were found to be equal to 60% thus showing high effectiveness of the process. The obtained results indicate that electrocatalytic properties of the electrodes change over time as the oxidation of cyanide is carried out. Nevertheless, a Ti electrode galvanostatically covered with a Pt layer of 600 nm average thickness shows higher stability, making it applicable for effective anodic utilization of cyanide ions.

Insertion of industrial waste into the ceramic matrix is one of the heavy metal binding technologies, allowing to obtain products fit for use or to reduce the volume of waste before final disposal at the same time. The properties of phosphating process waste and opportunities for its stabilization in the ceramic matrix are investigated in this study.Before investigation of stabilization a thermogravimetric analysis of phosphating sludge has been performed. The sludge was heated at 400, 600 and 1000 °C, and SEM images of sludge were made. The SEM images show that re-crystallization processes occur during the heating of the sludge.Ceramic samples for leaching tests were formed by adding 5 and 10% of phosphating sludge to the clay mass and by burning them at 900–1050 °C for 1–4 hours. The results of the leaching tests showed that the concentration of heavy metals from the burned ceramic samples containing 5 and 10% of phosphating sludge is less than the detection limit of the instrument, and at the same time it is below the allowable limits set out in the Wastewater Management Regulation. In this way, phosphating sludge stabilization in the ceramic proved as effective heavy metals immobilization and hazardous waste decontamination.

Published: January 2025

The gel weak base anion exchanger Purolite A847 has been proofed and compared with the macroporous strong base anion exchanger Purolite A500PS as a suitable adsorbent for the simultaneous removal of free cyanide and Ag-CN complex from an alkaline aqueous mixture under batch and fixed bed conditions. The determined capacities of Purolite A847 are apparently lower than those of Purolite A500PS and depend on the concentration of free cyanide in a solution: at higher concentrations of free cyanide the total capacity of an anion exchanger is lower. The experimental adsorption data obtained in batch were interpreted in terms of the pseudo-second-order reaction rate (qe, initial sorption rate h, rate constant k2) and intraparticle diffusion kinetic models. The values of qe, h and k2 for free cyanide on Purolite A847 were lower than those of the Ag-CN complex. Sorption of free cyanide and the Ag-CN complex from the alkaline mixture on Purolite A847 corresponds to the general selectivity order for weak base anion exchangers. Column dynamic behaviour peculiarities were studied with the selected breakthrough concentration in an effluent of 0.1 mg/L of silver or free cyanide. The experimental data were analyzed using the Yoon and Nelson empirical model parameters (rate constant K, time required for 50% breakthrough τ,removal capacity Q). The increase in free cyanide influent concentration parameters τAg(I) and QAg(I) for Ag-CN complex sorption on Purolite A847 decreases markedly when KAg(I) increases, while on Purolite A500PS τAg(I) and QAg(I) increase with slight changes in KAg(I). The regeneration of both the anion exchangers Purolite A847 and Purolite A500PS using 5% NaOH is sufficiently effective, with a higher recovered amount of free cyanide and a lower amount of the Ag-CN complex from Purolite A500PS.

Flavocytochrome b2 (fcb2) (EC 1.1.2.3) is a 4 × 58 kD homotetrameric FMN and heme containing enzyme localized in the intermembrane space of yeast mitochondria. During the catalysis, FMN oxidizes L-lactate to pyruvate. Subsequently, the reduced FMN transfers electrons to the heme cofactor, which subsequently reduces cytochrome c. The kinetic properties and thermostability of the enzyme depend on its source, and these factors may be important in the construction of biosensors for L-lactate based on fcb2. In this work, we have investigated the kinetic properties of fcb2 from the thermotolerant methanotrophic strain Hansenula polymorpha. Like in our previous studies of Saccharomyces cerevisiae fcb2 [1], H. polymorpha fcb2 exhibited biphasic Lineweaver–Burk plots at fixed L-lactate concentrations using varied ferricyanide concentrations. It reflects the accep­tance of electrons from both the reduced FMN and heme after the slower intramolecular FMN-to-heme electron transfer. At the infinite L-lactate concentration, the maximal rate of ferricyanide reduction is close to 120 s–1. The maximal rate of cytochrome c reduction is close to the second (slower) phase of ferricyanide reduction, because cytochrome c accepts electrons only from heme. The reaction product pyruvate inhibits H. polymorpha fcb2 in a mixed way at the millimolar concentration, and decreases the maximal rates of both fast and slow phases of ferricyanide reduction.

Interior Design of Organic Restaurant From Farm To Table in Pandaan
Authors: Citra Aurellia , Ambar Mulyono  
Published: January 2025

The development and competition of the food industry are currently skyrocketing in tandem with the progress of the times and the growth of the world population. To swiftly expand the food supply, a variety of physical and chemical techniques are created and put to use. Indirectly or directly, this lowers the value of healthy food, which has detrimental effects including the widespread availability of processed fast food, which encourages unhealthy eating habits and lifestyles. One of the reasons consumers choose fast food is lifestyle change, which makes quick food that has a savory flavor and small servings a suitable choice. Unfortunately, ready-to-eat food does not provide enough nutrition and nutrients needed. Thus, a common attempt to ensure that the body gets all the nutrients it requires is to lead a healthy lifestyle and consume organic food.

Pandaan's organic restaurants' design still falls short of raising people's understanding of the value of eating healthfully. Given this, the field of interior design must play a part in interior design, which includes educating the public about the significance of maintaining consumption that enters the body through restaurant design. This restaurant design plan aims to sell food and beverages, provide comfort, arrange, shop, receive, and process commodities, and entice customers to visit. It is believed that this farm-to-table organic restaurant's design would address the issues faced by the restaurant.
