Long-time monitoring studies recently indicated that newts are in decline in many regions. Motivated by the above-mentioned, in the year 2019, we started monitoring the newt populations from the Jiu Gorge National Park (JGNP) in the Romanian Carpathians, 10 years after the previous study on the same topic. Compared with other areas where newts are in decline, we identified new distribution locations of the two newt species which are present in the park. Also, the previously known populations have greatly increased. Thus, the Lissotriton vulgaris population increased 2.58 times in 10 years, and the Triturus cristatus increased 1.80 times in 10 years. At the same time, in areas from JGNP affected by human activities in the past (abandoned quarry and areas adjacent to the railway), the newts extended their range in the last years and occupied artificial aquatic habitats. In the case of the populations from the natural habitat, the temporal dynamics and the ratio between sexes and species followed the same evolution as in the case of other populations from Romania. The increase of newt populations from JGNP in the last 10 years was most probably a consequence of the reduced human pressure, corroborated with the large surface occupied by native forests in the park. Thus, in natural areas, probably the best management measures for both newt species are not represented by direct (invasive) human interventions but by the conservation of the natural habitats used by the newts. A protected area should maintain the conservation status at least at the present level, and if the region is natural, this fact will maintain and also increase the newt and probably other amphibian populations.

The aim of the study is to describe sirri marriage as one of the factors in the problems that occur in voter data and the implications of the impact of sirri marriage on voter data in Palu City. The issues raised are how the implications of the impact of sirri marriages on voter data in Palu City and how the legal analysis of the results of sirri marriages on voter data in Palu City. The research method used is  qualitative method  and the data was gathered through field observation, in-depth interview, and documentation. The  methodologyy was  reinforced by the Maqashid Asy-Syariah approach. The results of the study indicate that sirri marriage is one of the problems with voter data, namely in the process of updating voter data. The impact is that it has a negative impact on the election process, namely the loss of voting rights, the occurrence of multiple voter list problems, and for children if there is no data recording, they also cannot be registered on the voter list. With the Minister of Home Affairs No. 8 of 2019, children from sirri marriages can record their identities, it's just that many other children's rights will be lost, it is better for the perpetrators of this sirri marriage and their children to be advised to do isbat marriage so that their marriage is recorded.

Non-dental study of the ‘functional matrix’ hypothesis
Authors: Mollenbauer Danielle I.
Published: January 2024

An exploratory study was undertaken to obtain data on arm measurements of competitive female tennis players (n = 30) at three age levels — prepubertal (10-12years), post-pubertal (16-18years) and mature (45-70years). They were matched with persons who did not play with racquets but who had generally played sport (non-racquet sports persons, n = 30). Comparisons were to be made between the arms they preferred for playing tennis with their other (non-preferred) arms, and with the arms of non-racquet sports persons. The results suggest that competitive female tennis players differ from non-racquet sports persons, in that these tennis players have ignificantly shorter preferred forearm bone length and greater preferred forearm girth measurements than the non-racquet persons, because their preferred forearrn length was longer. These findings were most prominent in the post-pubertal group, which indicates a study to explore the Epigenetic hypothesis using arms is justified. The fact that it was less prominent in the older age group could be explained by the observation that the older players did not stroke the ball as aggressively. The results of this study also indicated that there were no significant differences between tennis players and non-tennis players in ponderal indices, preferred grip strength or preferred elbow and wrist widths. Therefore the results suggest that the phenomenon should be studied in, rather than extrapolated to, the maxillo-facial region.

The Bond Strength of Orthodontic Resins to Porcelain
Authors: White Gregory J. , Tyas Martin J.
Published: January 2024

Orthodontic brackets were bonded to one of two porcelain surfaces using a self-cured or one of two light-activated orthodontic bonding resins. The porcelain surfaces were either glazed (control) or de-glazed (experimental) by being subjected to either 1.23% APF for 4 minutes or roughened with a Busch silent wheel. The bonds were tested to failure in shear mode on a universal mechanical testing machine. For one porcelain, there was no significant difference in the mean bond strengths between the control and the APF-treated surface, but for the second porcelain the mean bond strength was significantly greater when the surface was de-glazed by abrasion. It is considered that the mean bond strengths may be inadequate to withstand manipulations associated with routine orthodontic therapy.

Computers and the Orthodontist
Authors: Weekes William T.
Published: January 2024

Dentofacial Planner Plus (DFP) is a computerised cephalometric program that enables rapid and accurate analysis of a cephalogram to aid in treatment planning. In addition, a video image of a patient’s profile can be linked to the digitised cephalogram. Manipulation of the tracing will produce corresponding changes in the video image. Simulations of orthodontic treatment or orthognathic surgery changes are therefore possible. This becomes a valuable aid in treatment planning, communication with the oral surgeon and patient education.
Feasibility Study of New Geothermal System for Heating Premises and Thermal Complexes: Experimental Investigation of Water-Air Heat Exchanger in the East of Algeria
Authors: Chettir Abderrahmane , Labed Adnane , Moummi Noureddine , Sayad Achraf
Published: January 2024

This paper constitutes a new technological solution for the exploitation of one of the most important geothermal deposits located in the locality of Biskra (South-east Algeria). This is the Albian aquifer whose hot waters from boreholes, hot springs and spas are poorly exploited while ambient temperatures during winter periods reach very low levels, especially at night. The principle of this geothermal system is to immerse a PVC tubular water-air exchanger in a pool permanently supplied with hot water from a low-energy geothermal borehole with a high flow rate. The choice of PVC material is attributed to the fact that hot geothermal waters are generally of an aggressive composition to steels and metals in general. The geothermal air heater allows the heating of the ambient cold air which is introduced into the exchanger and then extracted hot using an extraction fan. The hot air is then diffused into premises for heating during the winter season. The improvement in the performance of this type of exchanger is highlighted, in particular by acting on the number of pipes of the exchanger and the air flow rate using geothermal energy (low energy) as a source of renewable and clean energy. The experimental results obtained showed that the energy gain is a function of the length of the exchanger and the air flow rate. This gain can be up to 20°C between the inlet and outlet of the miniature exchanger model, which means that the proposed solution could be technically feasible.

Published: January 2024

Background: Taurodonsia is a dental anomaly that undergoes vertical dilation of the pulp chamber and has a short root. Teeth with taurodonsia affected by caries to the pulp must be treated endodontically first before restoration.  Case Report: a 4-year-old girl came in complaining of cavities in her lower jaw. After clinical examination, 84 teeth experienced deep dentin caries and from the results of radiographic photos, it was found that caries was almost close to the pulp horn with a large pulp chamber and short roots. The endodontic treatment carried out is pulpotomy and after that the final restoration uses a stainless steel crown. Conclusion: Taurodontia is a rare occurrence that requires a thorough clinical and radiographic examination to aid diagnosis and appropriate treatment planning. Pulpotomy can be an endodontic treatment option for primary teeth experiencing taurodontia based on objective and subjective considerations of the patient's condition

Analysis of factors affecting the excess profitability of mutual funds in Russia for 2015-2022
Authors: Arshakian Roza Araikovna , Mironenkova Marina Vladimirovna
Published: January 2024

The relevance of the study of financial market instruments is undeniable and well aligned with the achievement of Russia's national development goals until 2030. The subject of this article is the excess return of Russian mutual funds (MF) in the period from 2015 to 2022. The authors analyzed in detail the scientific literature and took as a basis the conclusions and results obtained in previous studies on similar topics. The aim of the study was to find the factors determining the excess return of mutual funds, which is the difference between the return of the funds and the return of the selected benchmark. The study was based on data from Investfunds Internet portal, which provides information on investment assets for a wide range of people. Econometric analysis was conducted based on an unbalanced panel consisting of an average of 185 funds per year. To achieve the objective, we studied already existing econometric models for analyzing excess fund returns and used them to construct a pass-through regression model and a fixed-effects model. Analyzing the performance of mutual funds depending on their parameters will allow investors to get relevant recommendations about which fund should be preferred to buy a share in its portfolio, which corresponds to the scientific novelty of the study. The main conclusion of the study is that using econometric criteria, the fixed-effects model was selected as the best of the constructed models. A notable contribution of the authors to the study of the topic is the identification of the main aspects that investors should pay attention to when choosing a mutual fund, namely funds with a high net asset value, the object of investment of which are stocks and money, and the direction of investment - precious metals.
Optimization of Lift-Plus-Cruise Vertical Take-Off and Landing Aircraft with Electrified Propulsion
Authors: Bhandari Rajan , Aman Mishra Aashutosh , Chakraborty Imon
Published: January 2024

Conventional aircraft sizing methods face challenges in analyzing all-electric or hybrid-electric novel aircraft configurations, such as those for urban air mobility applications. The vast design space containing both continuous and discrete design variables and competing design objectives necessitates searching for not necessarily a unique optimal design but rather an array of Pareto-optimal designs. This paper uses the Parametric Energy-Based Aircraft Configuration Evaluator, an aircraft sizing framework for novel aircraft and propulsion system architectures, to pursue multi-objective optimization of a lift-plus-cruise urban air mobility aircraft with all-electric, hybrid-electric, and turbo-electric propulsion system architectures using Nondominated Sorting Genetic Algorithm II. The optimization cases considered include multiple objective functions, such as maximum takeoff mass, mission time, energy and propulsion mass fraction, and energy used per unit distance per unit payload. Optimization was performed for trip distances of 80, 120, and 150 km and battery specific energy levels of 350 and 400 Wh/kg. Except when mission time was an objective function, Pareto-optimal designs occurred near the lower bound of the velocity range. Raising that bound had an impact on the architectural composition of the final generation. All-electric architectures appeared exclusively for lower trip distances, hybrid-electric designs appeared for longer trip distances, and turbo-electric designs only appeared for combinations of longer trip distances, a higher minimum cruise speed, and a lower battery specific energy level. The sizing results were sensitive to assumptions regarding the overload capacity of lift propulsor motors in postfailure conditions.

Diarrhea, colitis, chronic cough, asthma, tuberculosis, and improved digestive function are only a few of the conditions for which the ayurvedic formulation Babbularishta is utilized. Gallic acid is one of the active ingredients in babbularishta, a commercially available ayurvedic medicine. The purpose of this study was to develop a standard for the quality of commercially available Babbularishta by measuring its alcohol content and pH. To meet World Health Organisation (WHO) standards, an high-performance liquid chromatography (HPLC) and ultraviolet (UV) method was devised for quantifying the main component, gallic acid, in babbularishta. Gas chromatography and redox titrimetry were used to confirm the accuracy of the formulation determined during the development process. The formulation was further tested for pharmacological activity, elemental makeup, pesticide traces, and heavy metal concentration.

In recent years, the problem of the removal drug from wastewater has become one of the most important global problems due to the accumulation of large quantities of drugs on the surface of the water, which causes a lack of penetration of sunlight into water contaminated with drug, and this leads to a reduction in aquatic life forms for all living organisms and also leads to problems large environmental impacts and many dangerous diseases for humans. An attempt was made to prepare an environmentally friendly, economical and available surface that has a high absorption capacity to remove the contaminants of pharmaceuticals such as amoxicillin (AMX) drug. In this study, waste material such as white marble was used as an absorbent material, and its adsorption properties were enhanced and activated by treating it with several acids (HCL, H2SO4, and HNO3). The prepared white marble before and after adsorption were characterized by field emission scanning electron microscopy (FESEM) and transmission electron microscopy (TEM). The influence of several parameters like contact time (5–120 minutes), initial concentration of drug (10–50 mg/L), adsorbent dosage (0.02–0.2 g), solution temperature (10–40oC), and pH (2–10) was estimated for adsorption method optimization. The equilibrium adsorption result was examined utilizing the isotherm Langmuir, and isotherm Freundlich models. The attained data indicated that, sorption was found to be fast, 84.44% within 1 hour.

This study aimed to produce b-cyclodextrin (β-CD) based nanosponges (NS) loaded with nitrofurantoin (NFN) to improve oral bioavailability, solubility, and dissolution rate while concealing bitter tastes. The cross-linker diphenyl carbonate and β-CD were reacted in various ratios (1:1, 1:2, 1:4, 1:6, and 1:8) to produce NFN-loaded NS. The developed NS were evaluated for phase solubility study, particle size, drug loading, polydispersity index, scanning electron microscope (SEM), zeta potential, fourier transform infrared (FTIR), differential scanning calorimetry (DSC), a study of phosphate buffer at pH 7.2 for in-vitro release and taste masking ability in human volunteers. Pure NFN showed nearly 100 mcg/mL solubility in ditilled water while at 1:8 (β-CD: DPC) ratio the solubility was found to be 250 mcg/mL, i.e., nearly 2.5 fold enhancement in solubility was observed. The SEM of the NFN-loaded NS (1:8 β-CD: DPC ratio) showed highly spherical surface morphology. For formulation containing a 1:8 proportion of β-CD to DPC, the average particle size was measured at 324.78 ± 10.45 nm, possessing a low polydispersity index of 0.196 ± 0.054. It was found that the zeta potential’s value was -20.59 ± 0.4 mV, indicating sufficient electrostatic repulsion to maintain particle dispersion. FTIR, DSC study reveled excellent drug and excipient compatability. As compared to pure NFN, NFN-loaded NS showed faster release in pH 7.2 phosphate buffer. Research conducted in-vitro showed a gradual release of NFN from pure NFN throughout a two-hour period. The plain NFN suspension was found to have a pronounced bitterness. With 3.95 ± 0.57 as the average score, while the NFN nanosponges (1:8 ratio) had a mean bitterness score of only 0.10 ± 0.00. These findings suggest that the NFN (1:8 ratio) has the capacity to thoroughly cover up the bitter taste of NF.
