Anthropometric parameters regarding the nutritional status of schoolchildren

- Objective. This study assesses the anthropometric parameters concerning the nutritional status of and establishes the prevalence of excessive weight, obesity, and malnutrition among schoolchildren in an educational institution on Colombia’s northern coast. Materials and methods. A quantitative correlational research was conducted. The sample included 556 children aged between 6 and 11 years (310 boys and 246 girls). Their weight, height, BMI, and nutritional status were evaluated, and the BMI/age variable (Z-score)was studied to determine the nutritional categories of underweight, normal, and excess weight (overweight and obese) through a descriptive analysis and analysis of variance (ANOVA) using an unbalanced factorial design. Results. Thinness and obesity cases were reported, with 21.43% (119/556) of the students experiencing some kind of nutritional disorder. Although no statistically significant differences were observed between the gender factor levels, ANOVA showed that male students tend to move farther from the expectedZ-scores. Conclusion: The average Z-score of young students is usually closer to the expected score, whereas that of older students is farthest from expectation, in addition to showing greater variability between measures.

What are the impetuses Behind E-health applications’ self-management services’ ongoing adoption by health community participants?

Over the past 20 years, the identification of interventions related to healthcare management has been greatly facilitated by improvements in the well-being and health of the entire population. However, regardless of the positive developments in smart health applications and e-health research, there are two important gaps, (1) the role of gamification variables in the continued use of eHealth applications has not been adequately assessed, and (2) the extent to which people’s perception of the continued use of e-health applications is encouraged through habit. Customers and companies can derive considerable value from exploring E-Health applications’ health self-management services. Accordingly, estimating such services’ ongoing adoption by customers is aimed for in this research, with habits, intrinsic and extrinsic variables incorporated into a study model which is then tested. This paper examined perceived autonomy, perceived competence, perceived relatedness has positively related to enjoyment and habit. Reward has positively related to perceived autonomy and continued to use. Enjoyment and Habit have positively associated with the decision to continue to use in e-Health Apps. 269 individuals who have used Chinese e-health applications comprised the data collection sample, being reached via an online questionnaire. Data analysis was undertaken using Partial Least Squares Structural Equation Modelling (PLS-SEM). It was found that the ongoing adoption of e-health self-management services was perpetuated to a greater extent by intrinsic variables; in terms of strategizing for companies’ e-services, the results can inform this process.
Empirical Dynamic Modeling for Low-Altitude UAV Propagation Channels

During the last few years, with the decrease of their sizes and costs, Unmanned Aerial Vehicles (UAVs) became more feasible for their use in general-purpose applications. As an important basis for UAV applications, the Air-to-Ground (A2G) radio propagation channel has gained attention in the channel modeling literature. However, whereas the A2G propagation channel is inherently dynamic (time-varying), the majority of the available models do not consider such a time-variability. This paper proposes a channel multi-path component (MPC) tracking algorithm and shows its ability to analyze the data collected by a real A2G measurement campaign in a suburban environment. Based on the obtained results, a time-varying statistical channel model for A2G communications in realistic suburban scenarios is proposed. The model is able to stochastically characterize parameters related to the birth and time-of-life of the multi-path components (MPCs), as well as their evolution in terms of delay, Doppler frequency or magnitude. Correlation coefficients to relate different channel characteristics are also obtained. Our work shows that the MPCs evolution over time for the UAV A2G channel can be described by simple regular patterns.
Earthworm Diversity, Forest Conversion and Agroforestry in Quang Nam Province, Vietnam

The conversion of natural forests to different land uses still occurs in various parts of Southeast Asia with poor records of impact on ecosystem services and biodiversity. We quantified such impacts on earthworm diversity in two communes of Quang Nam province, Vietnam. Both communes are situated within buffer zones of a nature reserve where remaining natural forests are under threat of continued conversion. We identified 25 different earthworm species, out of which 21 were found in natural forests, 15 in agroforestry, 14 in planted forests, and seven each in annual croplands and home gardens. Out of the six species that were omnipresent inhabitants of all observed habitats, Pontoscolex corethrurus largely dominated habitats with intensive anthropogenic activities but was rare in natural forests. Natural and regenerated forests had a much denser earthworm population in the top 10 cm of soil rather than in deeper soil layers. We conclude that the conversion of natural forests into different land uses has reduced earthworm diversity which can substantially affect soil health and ecosystem functions in the two communes. Protection of the remaining natural forests is urgent, while the promotion of a tree-based farming system such as agroforestry can reconcile earthworm conservation and local livelihoods.
Architectural and Ultrastructural Variations of Human Leukocyte-Rich Platelet-Rich Fibrin and Injectable Platelet-Rich Fibrin

Background: Platelet-rich fibrin (PRF) architecture and ultrastructure plays a crucial role in regulating and coordinating the cellular functions and provides a physical architecture, mechanical stability, and biochemical cues necessary for tissue morphogenesis and homeostasis. No study consciously reported the variation in architecture, ultrastructure, and morphology of leukocyte-rich PRF (L-PRF) and injectable PRF (i-PRF). Objective: Hence, the present study was aimed to evaluate the fibrin architecture, ultrastructure, and cell contents of autologous L-PRF and i-PRF. Materials and Methods: The autologous L-PRF and i-PRF were prepared from blood samples of healthy donors. The morphological and structural variations were assessed by histopathology, atomic force microscopy, confocal laser scanning microscope, and field emission scanning electron microscope. Results: Disparity was found on architecture and ultrastructure of L-PRF and i-PRF fibrin network. The variation in platelet and leukocyte concentration attributed to the fibrin conformational changes. L-PRF shows thick fibrins with rough surface, whereas in i-PRF, smooth thin fibrins. Conclusions: The current study revealed that there is heterogeneity between L-PRF and i-PRF fibrin matrix architecture, ultrastructure, platelets, leukocytes, and the fibrin content. These speculate that the diameter, width, roughness, and smoothness of fibrin fibers, pore size, and shapes of L-PRF and i-PRF matrix may initiate and mediate the scaffold functions differently.
Evaluation of the serum antioxidant status in patients with chronic periodontitis

Aim: The aim of this study was to evaluate any measurable change in antioxidant and free radical scavenger status in periodontal disease. Materials and Methods: A total of forty subjects consisting of twenty test subjects and twenty controls were recruited for the study. The antioxidant defense status in serum (in terms of superoxide dismutase (SOD), glutathione peroxidase [GSHPx] and catalase [CAT]), serum lipid peroxidation (in terms of malondialdehyde), and free radical scavengers (Vitamin C) was assessed. Results: Significant differences were noted between tests and controls. Negative correlation was observed between the values of lipid peroxidation and that of SOD, GSHPx, and CAT. Our study confirmed that lowered level of SOD, CAT, and GSHPx is associated with hyper lipid peroxidation in periodontal disease. Conclusion: It is now clear that the free radicals play a critical role in the initiation and progression of periodontal disease. Furthermore, the results of the present study may have important therapeutic implications in terms of the use of the antioxidants in periodontal therapy to prevent tissue destruction.
Effect of Selected Drying Methods and Emerging Drying Intensification Technologies on the Quality of Dried Fruit: A Review

Drying is one of the oldest methods for food preservation that removes the water from fruit and makes it available for consumption throughout the year. Dried fruits can be produced by small- and large-scale processors, which makes them a very popular food among consumers and food manufacturers. The most frequent uses of drying technology include osmotic dehydration, vacuum drying, freeze-drying and different combinations of other drying technologies. However, drying may provoke undesirable changes with respect to physiochemical, sensory, nutritional and microbiological quality. Drying process energy efficiency and the quality of dried fruits are crucial factors in fruit drying. Recently, innovative technologies such as ultrasound, pulsed electric field and high pressure may be used as a pretreatment or in combination with traditional drying technologies for process intensification. This could result in quality improvements of dried fruits and enhanced efficiency and capacity of the production process, with a positive impact on environmental and economic benefits.

Trade openness and economic growth nexus: Exploring the role of institutional quality in Nigeria

Abstract This study attempts to fill the prior knowledge gap in the nexus between trade openness and economic growth in Nigeria by incorporating the role of institutional quality. The study covers the period from 1984 to 2017 and employs three indicators of trade openness including total trade, import trade, and export trade. Cointegration among the variables is examined using the ARDL bounds testing approach. The results provide evidence of a long-run relationship among the variables. The estimates suggest that export trade has a significant positive impact on economic growth while the impact of import trade on economic growth is negative and significant. The results also show that the negative long-run effects of import trade on economic growth in Nigeria decreases as institutional quality (quality of governance) improves. These empirical results have important policy implications for Nigeria. Among others, this study highlights the needs to improve the quality of governance in the country. Good governance and quality institutions can help channel the dividends of trade openness into growth-enhancing activities.

Characteristics of Eukaryotic Plankton Communities in the Cold Water Masses and Nearshore Waters of the South Yellow Sea

Eukaryotic plankton are important parts of the marine biome and play an important role in maintaining the stability of marine ecosystems. In order to characterize the eukaryotic plankton communities in the South Yellow Sea Cold Water Mass (CWM) and the South Yellow Sea nearshore waters (NW) in October 2019, Illumina high–throughput sequencing was performed using the 18S rDNA V9 region as the target gene. Environmental factors (depth, pH, salinity, temperature, Chl a, nitrate, nitrite, ammonium, silicate, phosphate) in two sea areas were measured, and their correlations with abundance and diversity of eukaryotic plankton were analyzed. A total of 807 species of plankton were identified, of which 663 species in 24 categories were from the CWM area, and 614 species in 26 categories were from NW. The total phytoplankton abundance in CWM waters was higher than that in NW. Dinophyta and Bacillariophyta were the most abundant phyla of phytoplankton in the two areas. Arthropoda and Cnidaria were the major zooplankton taxa. The dominant fungal population was mainly Basidiomycota. Both the CWM and NW have effects on dissolved inorganic nutrient concentrations and plankton abundance. Environmental factor correlation analysis showed that the concentration of dissolved inorganic nutrients within the CWM increased with water depth and the abundance of plankton gradually increased. Ammonium salts, nitrates, phosphates, silicates and water depth were important factors affecting phytoplankton growth. Phytoplankton abundance increased with increasing concentrations of inorganic nutrients. Bacillariophyta showed a strong positive correlation with silicates and depth. Depth and microscopic phytoplankton abundance were important factors influencing the structure of the zooplankton community.
Microbial ecology of coral-dominated reefs in the Federated States of Micronesia

Microorganisms are central to the functioning of coral reef ecosystems, but their dynamics are unstudied on most reefs. We examined the microbial ecology of shallow reefs within the Federated States of Micronesia. We surveyed 20 reefs surrounding 7 islands and atolls (Yap, Woleai, Olimarao, Kosrae, Kapingamarangi, Nukuoro, and Pohnpei), spanning 875 053 km2. On the reefs, we found consistently higher coral coverage (mean ± SD = 36.9 ± 22.2%; max 77%) compared to macroalgae coverage (15.2 ± 15.5%; max 58%), and low abundances of fish. Reef waters had low inorganic nutrient concentrations and were dominated by Synechococcus, Prochlorococcus, and SAR11 bacteria. The richness of bacterial and archaeal communities was significantly related to interactions between island/atoll and depth. High coral coverage on reefs was linked to higher relative abundances of Flavobacteriaceae, Leisingera, Owenweeksia, Vibrio, and the OM27 clade, as well as other heterotrophic bacterial groups, consistent with communities residing in waters near corals and within coral mucus. Microbial community structure at reef depth was significantly correlated with geographic distance, suggesting that island biogeography influences reef microbial communities. Reefs at Kosrae Island, which hosted the highest coral abundance and diversity, were unique compared to other locations; seawater from Kosrae reefs had the lowest organic carbon (59.8−67.9 μM), highest organic nitrogen (4.5−5.3 μM), and harbored consistent microbial communities (>85% similar), which were dominated by heterotrophic cells. This study suggests that the reef-water microbial ecology on Micronesian reefs is influenced by the density and diversity of corals as well as other biogeographical features.
Combining Chemical Functionalization and FinFET Geometry for Field Effect Sensors as Accessible Technology to Optimize pH Sensing

Field Effect Transistors (FETs) have led the progress of applications measuring the acidity in aqueous solutions thanks to their accuracy, ease of miniaturization and capacity of multiplexing. The signal-to-noise ratio and linearity of the sensors are two of the most relevant figures of merit that can facilitate the improvements of these devices. In this work we present the functionalization with aminopropyltriethoxysilane (APTES) of a promising new FET design consisting of a high height-to-width aspect ratio with an efficient 2D gating architecture that improves both factors. We measured the transistor transfer and output characteristics before and after APTES functionalization, obtaining an improved sensitivity and linearity in both responses. We also compared the experimental results with a site-biding model of the surface buffering capacity of the APTES functionalized layers.

Structure of the amorphous titania precursor phase of N-doped photocatalysts

Amorphous titania samples prepared by ammonia solution neutralization of titanyl sulphate have been characterized by chemical and thermal analyses, and with reciprocal-space and real-space fitting of wide-angle synchrotron X-ray scattering data. A model that fits both the chemical and structural data comprises small segments of lepidocrocite-type layer that are offset by corner-sharing as in the monoclinic titanic acids H2TinO2n+1·mH2O. The amorphous phase composition that best fits the combined chemical and scattering data is [(NH4)3H21Ti20O52]·14H2O, where the formula within the brackets is the cluster composition and the H2O outside the brackets is physically adsorbed. The NH4+ cations are an integral part of the clusters and are bonded to layer anions at the corners of the offset layers, as occurs in the alkali metal stepped-layer titanates. The stepped-layer model is shown to give a consistent mechanism for the reaction of aqueous ammonia with solid hydrated titanyl sulphate, in which the amorphous product retains the exact size and shape of the reacting titanyl sulphate crystals.
