: Microbiota is considered an organ that affects the health of the human body and includes many microorganisms such as bacteria, yeast, mold, viruses, protozoa, and archaea. Microorganism such as Candida sp., a part of the microbiota, is known to cause diseases in the case of opportunistic pathogens under various conditions. Yeast loads and species in the oral mycobiota of young individuals aged 18-25 were determined in our study. Two methods, centrifugation and dilution, were used to determine the oral yeast load. Samples were taken from 31 individuals for the centrifugation method, including 29 for the dilution method and five of these individuals. The samples were inoculated on Sabouraud 2% Dextrose Agar (SDA) and SDA containing chloramphenicol (SCAF). As a result, in young individuals aged 18-25, the oral yeast load was 0.01±0.01 and 1.87±0.01 log CFU in SCAF, and it was 0.01±0.01 and >3.00±0.01 log CFU in SDA. A total of 400 isolates were taken from the counting plates, and 140 were determined to be yeast by gram staining. Germ tube test of the isolates determined to be yeasts determined that 108 were probably Candida albicans or Candida dubliniensis . 140 isolates were also identified by MALDI-TOF MS. Isolates were identified as C. albicans (38.58%), C. albicans or C. africana (3.57%), C. dubliniensis (32.86%), C. parapsilosis (20%), C. inconspicua (2.14%), Pichia manshurica (2.14%), and Wickerhamomyces subpelliculosus (0.71%). It has been determined that young individuals between the ages of 18-25 carry Candida species in their oral mycobiota.

: Classical Quantitative Genetics offers statistical approaches to estimate variance components of important agronomical traits, such as diseases resistance, through different experimental designs. However, the use of RIL in these approaches is limited. As Recombinant Inbred Lines are considered important for developing special breeding projects, we propose a new methodological approach to simultaneously estimate broad and narrow sense heritabilities. This proposed model was applied to calculate heritabilities for resistance to corn ear rots caused by Fusarium verticillioides in three independent RIL populations analyzed by nested ANOVA. Fusarium Incidence (%) and Fusarium Severity heritabilities were significant. The proposed approach proved to be useful for estimating broad and narrow sense heritabilities in the same environment and with these genotypes which is advantageous for corn breeders.

: Internet of Things (IoT) can be considered as one of the emergent research topics, which linked several sensor enabled devices. Wireless sensor networks (WSNs) remains a key enabling technology for IoT environment due to their possibility in placing different types of essential smart city applications, like healthcare, smart cities, environment monitoring, etc. At the same time, effectual utilization of energy is required for the design of energy-efficient data transmission strategy in the IoT environment. In this view, this study develops a novel multi-objective sand piper optimization based clustering with multi-hop routing (MOSPO-CMR) technique to IoT assisted WSN. The proposed MOSPO-CMR technique intends to effectively choose cluster heads (CHs) and derive optimal routes to BS. The MOSPO-CMR technique initially performs cluster construction process by the election of CHs using three variables namely Residual energy (RES), distance to BS (

: The image of an athlete's ankle joint injury can help to check whether the athlete's ankle joint is damaged, and plays a very important role in clinical diagnosis. To address the problem of poor segmentation effect of traditional athletes' ankle injury image segmentation algorithm, an ankle injury image segmentation algorithm based on residual double attention U-Net model is proposed. First, the region of interest is extracted from the original ankle injury image. After translation, rotation and turnover, the image data is expanded. Second, the residual structure is used to adjust the gradient propagation and residual feedback of the segmentation framework, extract the attribute information in the region of interest

: The world is currently facing a severe economic crisis and the rational consumption and reuse of products, including waste are necessary. Agriculture wastes have importance containing beneficial and economic value matters, which unutilized may lead to environmental pollution. Date seed is one of these viable wastes with high nutritional value. Mass rearing of peach fruit flies is important to produce parasitoids for use in biological control programs or sterile insect techniques. In this study powder of date seeds were evaluated as an alternative diet for mass rearing of peach fruit fly Bactrocera zonata . The nutrient composition of the tested diet that contained date seed powder was rich in crude proteins (13.1%), crude carbohydrates (40.41), crude fats (4.6), crude fibers (8.4), and ashes (0.29). The results indicated that the date seed powder produced insects with quality parameters equivalent to FAO, IAEA/USDA standards, without differences with those reared on yeast. The histology of the reproductive system of B. zonata reveals that the female ovariole is of meristic-polytrophic type with successive stages of egg chambers. The male testis has a single long follicle with successive stages of spermatogenesis. Thus, date seed powder is a potential alternative diet for use in the mass rearing of the peach fruit fly.

Thus, authentication of digital images which are posted on social media websites is of paramount importance. Our social media should be intelligent enough to check on these forged images such that no false information spreads around society.
