Molecular epidemiology of seborrheic dermatitis/dandruff associated Malassezia species from northern India.

Malassezia is a commensal that sometimes become pathogenic under the influence of diverse factors. Several species of Malassezia are difficult to culture, making traditional methods of identification challenging. The problem with molecular typing of Malassezia in association with seborrheic dermatitis/dandruff (SD/D) arises due to the unavailability of these fastidious yeast cultures. The aim of the study was to investigate the association between fluorescent amplified fragment length polymorphism (FAFLP) genotypes, disease state (SD/D), and the geographic distribution of M. globosa, M. restricta and M. arunalokei. In total 154 isolates representing M. globosa (n=85), M. restricta (n=55), and M. arunalokei (n=14) from lesional/non-lesional areas of SD/D patients and healthy controls residing in the rural (n=77) and urban (n=77) areas of northern India were included. A strategy based on the FAFLP methodology was developed using two endonuclease enzymes (EcoRI and HindIII). M. globosa, M. restricta, and M. arunalokei formed eleven, three, and two FAFLP clusters respectively. Disease-specific strains of M. restricta and M. arunalokei preferentially tend to cause SD/D. M. restricta and M. arunalokei showed less genetic variation. M. globosa showed higher genetic diversity. FAFLP clusters revealed the existence of geographically specific strains in M. restricta, M. arunalokei, and M. globosa. Our findings suggest that certain Malassezia strains are not only disease-specific but also geographically distinct.

Modeling habitat suitability to predict the potential distribution of the Sri Lankan Green Pit Viper

Snake distribution and habitat modeling serve multiple valuable purposes, one of which involves establishing a systematic approach for collecting and assessing data related to the presence and influence of diverse factors on snake distribution patterns. The main objective of this study is to explore the habitat association of the Sri Lankan Green Pit Viper (Peltopelor trigonocephalus) and develop models to assess the suitability of different habitats within the island Sri Lanka. We modeled the suitable habitat for this species using the maximum entropy algorithm, combining presence data collected over two years (from April 2021 to April 2023) with a set of seven environmental variables (annual precipitation, annual mean temperature, precipitation of coldest quarter, elevation, land use, isothermality, Euclidean distance to water). We assessed the importance of different environmental variables through jackknife tests. We evaluated the predictive ability of the models using the area under the receiver operating characteristic curve. We discovered that the primary explanatory variables influencing the distribution of the species were annual mean temperature, annual precipitation, and elevation, contributing significantly at 35%, 31.6%, and 20%, respectively. The Sri Lankan Green pit viper inhabited riparian, forest, and open habitats, with the highest number of individuals recorded in riparian areas. We presented the first habitat suitability models for the Sri Lankan Green Pit Viper, offering valuable insights for conservation biologists and land managers involved in preserving this species.

Heat transfer in a wet porous moving inclined longitudinal fin exposed to convection and radiation in the presence of shape-dependent hybrid nanofluid: Adomian decomposition Sumudu transformation approach

This research paper investigates the thermal examination of a non-integer-ordered mobile fin situation with a hybrid nanofluid flowing past it at an unceasing speed U. The combination approach is utilized to evaluate the physical and thermal characteristics of the hybrid nanofluid, excluding the thermal conductivity and dynamic viscosity. This governing equation is transformed into a dimensionless form and the Adomian Decomposition Sumudu Transform method is employed to solve the conundrum of a moving fin immersed in a hybrid nanofluid. The reliability of this research has been confirmed by verifying the results through a comparison with numerical simulations. The influence of diverse factors on the thermal overview for varying noninteger values alpha is analyzed and presented in graphical representations. Moreover, the analysis reveals that the highest heat flux occurs in the scenario where nanoparticles with spherical-platelet shapes are combined. This is succeeded by the spherical-cylindrical combination, and finally, the spherical-spherical pairing, in terms of heat flux magnitude. Here, we discovered that the temperature at the fin tip decreases by 11.19141 % for s-s shaped nanoparticles, 10.45649 % for s-c shaped nanoparticles and 10.21162 % for s-p shaped nanoparticles as the wet parameter (m2) increases by a factor of 400, and also when the radiation parameter is increased by 400 %, the temperature of the fin tip drops by 13.11313 % for s-s shape nanoparticles, 11.97076 for s-c shape nanoparticles and 11.653899 % for s-p shape nanoparticles.

Effects of disclosing inspection scores of health facilities

Health services are highly regulated and targeted for in-depth inspections by government officials in major part of the countries, aiming at the protection of patients from malpractice. In Brazil, the inspection of regulated professions costs approximately 3.3 billion reais (630 million US dollars) annually. Despite the substantial costs, there is lack of evidence on the quality of the public expenditures on regulation of health services. The Brazilian legal framework poses additional challenges to account for policy effectiveness, since professional regulatory bodies may adopt its own inspection strategy. A methodological alternative to deal with the complexity of public policies refers to the adoption of complex systems approach, considering the interaction between agents, the influence of diverse factors, and the possibility of emergence of patterns from bottom-up. Thus, the objective of the study was to present an agent-based model to investigate two inspection strategies applied to health services: one strategy omits inspection scores from patients, whilst the other discloses the inspection scores. The results of the interactions between patients and clinics under different inspection strategies through computational simulation showed that transparency in inspection scores had no significant impact neither on patients' health nor on clinics’ compliance rate. Conclusions drawn in the light of public policy effectiveness indicate the possibility of adaptation of the model to other regulatory environments.

User-centered Design of Business Communities. The Influence of Diversity Factors on Motives to use Communities in Professional Settings

The professional use and implementation of social media or social media related applications are booming. Solutions like business internal communities promise to connect employees in a more flexible way than old-fashioned mailing lists or static network drives ever could. New solutions are perceived to support communication independent from time and space and in allow a more flexible way of communicating direct as well as indirect through the offer of different communication media (chat, voice over IP, mail, blog, etc.). But in contrast to remarkably good application scenarios, reality is not keeping up. Therefore more investigations of usage conditions and acceptance parameters are needed to find out which showstoppers interfere with a successful implementation. Due to the fact that acceptance by future users is one core condition for a successful implementation of software within operational structures and processes, this paper presents a study with focus on motivational issues to use business communities depending on diversity factors. In this study the focus is set on the diversity factors age, gender, social media expertise, achievement motivation, and perceived locus of control over technology (ploc). First results revealed that the classical user diversity variables age and gender do not influence the motives to use business communities. In contrast technology related diversity factors and achievement motivation revealed correlations with usage motives (r > .3). The most important motives were the need for information and autonomy. Achievement motivation showed the strongest correlation with the need for social interaction (r = .51), indicating that highly motivated people can be motivated to use a SNS if it facilitates social interaction.

Environmentally benign supercritical CO2 extraction of galanthamine from floricultural crop waste of Narcissus pseudonarcissus

The influence of diverse factors on the supercritical fluid extraction (SFE) with supercritical CO2 (scCO2) of galanthamine from bulbs of Narcissus pseudonarcissus cv. Carlton was investigated. The parameters that were studied were CO2 density (temperature and pressure), flow rate and plant material particle size and pre-treatment. The highest yield (303μg/g) was achieved by extracting 53–1000μm particle-size powdered dried bulb material moistened with NH4OH (25%, v/v) at 70°C, 220bar (690kg/m3) for 3h. Other N. pseudonarcissus alkaloids such as O-methyllycorenine and haemanthamine were also obtained. N. pseudonarcissus alkaloids as free bases are highly soluble in CO2 at a high pH as opposed to the slightly soluble salt form in which they are generally found in plants. Therefore, plant material pre-treatment with a base is an essential step for galanthamine extraction. Scanning electron microscope (SEM) results also revealed that the desorption of N. pseudonarcissus alkaloids from the plant material rather than the solubility of the alkaloids in the scCO2 plays a major role in this scCO2 extraction. This extraction method has a good potential for industrial application.

Eu geochemistry in magmatic rocks of continental marginal volcanic belts

The example of eastern Russia is employed to analyze the influence of diverse factors on the development of negative Eu anomalies in magmatic rocks at continental marginal volcanic belts. A strong correlation is identified between the relative value of Eu minima and the degree of Fe oxidation, Fe/(Fe+Mg) of mafic minerals, and an increase in the Eu minimum from basic to acid rocks. It is demonstrated that the value of the Eu minimum hardly depends on either the crystallization depth of the rocks and/or their alkalinity. Within individual tectono-stratigraphic zones, the value of Eu anomalies is independent of the age of the rocks, their affiliation with certain associations, and the basement structure of the volcanic zone. Rocks with clearly pronounced negative Eu anomalies belong exclusively to the ilmenite series that are formed under reduced conditions. The rocks of the magnetite series, which are formed under oxidized conditions, contain trivalent Eu, which behaves analogously to other REE.

Technological practicability of the numericalmodeling of induction heating process in steel pieces

This paper presents the numerical modeling (using the Finite Difference Method-FDM, and Finite Element Method- FEM) of the electromagnetic and thermal fields in a steel piece heated up inside an induction crucible furnace, and the experimental validations. Both modelings have been validated experimentally, so they can be used in designing the equipments and in the numerical control of induction heating process. The program based on FDM can be used in the first stage of designing due to the reduced CPU time. In this stage the inductor parameters and heating time can be estimated, and a study of the influence of diverse factors upon the heating process can be achieved. The FLUX 2D program can be used in the optimization stage, because it allows a more thorough analysis of the phenomena.

Influence of diverse factors on the variability in auxin and gibberellin contents in helianthus annuus L.

A mono- and bifactorial dispersional analysis has been applied to determine the rate of influence of different factors on variability in the contents of auxins (AIA) and gibberellins (GA3) in sunflower leaves and inflorescences. It was found that environmental conditions influenced very little the contents of the studied phytohormones, the greatest influence being manifested in line MB 514 which was treated with gibberellins. Diverse affinity of organs to GA3 was established in this line, as well as different functional roles of auxins and gibberellins, correlated with spatial isolation mechanisms. The ontogenetic phase had an important role in the variability of auxin content in leaves. The genotypes´ rate is mainly significant in the gibberellins contents` variability on the inflorescence level.
