Background: Hypertension is one of the most frequently encountered medical disorder in obstetrics practice and remain a major cause of maternal, fetal and neonatal morbidity and mortality. Objectives was to find out the high incidences of low serum magnesium in pre-eclampsia and eclampsia than in normal pregnancy.Methods: All consenting 50 cases of normal pregnant women and 50 women with pre-eclampsia attending antenatal clinic for checkup of ≥20 weeks who fulfills the inclusion and exclusion criteria were included in the study. Serum magnesium was measured by Calmagite method.Results: Out of 100 primigravidae 50 cases of pre-eclampsia women were in the age group of 18-30 years and the mean serum magnesium was 1.156±0.328. In contrast out of 50 cases of pregnant women were in the age group of 18-30 years and the mean serum magnesium was 1.907±0.321. The difference between the mean serum magnesium level in pre-eclampsia and normal pregnant women cases were statistically significant (p=0.0016). The study presented below it is clear that there are numerous factors that contribute to the causality of pre-eclampsia and from our analysis it was clear that the serum magnesium levels show an irregular pattern of fluctuations in cases suffering from pre-eclampsia and can be attributed to numerous physiological causes.Conclusions: Our study shows a significant reduction of serum magnesium levels in pre-eclampsia cases compared to normal pregnant women and occurrence of both maternal and neonatal complications with the serum magnesium levels decreased.

To overcome some of the limitations of activated carbon like efficiency, cost-effectiveness, and reusability, the present work deals with Cu(I)-based polyaniline (PANI) composite for the removal of reactive orange 16 (RO16) dye. Following the synthesis and characterization of formed Cu(I)-PANI composite, the batch experiments performed for the removal of RO16 dye indicated that the composite has the capacity to reduce the coloring from RO16. The experiments were conducted for the study of effects against changes in pH, time, and dose at room temperature, where we observed for a pH impact on the dye adsorption capacity in the range of 2–12. Among all, the optimal RO16 removal was found to be 94.77% at a pH of 4 and in addition, the adsorption kinetics confirmed to be pseudo-second-order with more suitability towards the Langmuir isotherm, where it is presumed to be the formation of a monolayer of dye molecule at the homogeneous absorbent surface. The calculated maximum capacity, qm, determined from the Langmuir model was 392.156 mg/g. Further application of isotherms to attain thermodynamic parameters, a slight positive value of S° for RO16 adsorption was observed, meaning that there is an increased randomness in the irregular pattern at the specific Cu(I)-PANI interface for an adsorption process. This mechanism plays an essential role in maintaining the effects of water pollution; and, based on the analysis therefore, it is prominent that the Cu(I)-PANI composite can be employed as a promising and economical adsorbent for the treatment of RO16 and other dye molecules from the sewage in wastewater.

Abstract: Heart diseases are the one of the primary reasons of human death today. There are many recent technologies are used to assist the medical professionals and doctors in the prediction of heart disease in the early stage. Prediction of heart disease is a critical challenge in the area of clinical data analysis. This paper introduces a technique to detect arrhythmia, which is a representative type of cardio vascular diseases. Arrhythmia refers to any irregular change from the normal heart rhythms, means that your heart beats too quickly, too slowly, or with an irregular pattern. The Electro Cardiogram (ECG) is used as an input for the arrhythmia detection. It displays the rhythm and status of the heart. This paper propose an effective ECG arrhythmia classification approach based on a deep convolutional neural network (CNN), which has lately demonstrated remarkable performance in the field of machine learning. It perform the classification without any manual pre-processing of the ECG signals such as noise filtering, feature extraction, and feature reduction. Keywords: Arrhythmia, ECG, deep learning, CNN, ResNet

AbstractSelf-organisation is a ubiquitous phenomenon in ecosystems. These systems can experience transitions from a uniform cover towards the formation of vegetation patterns as a result of symmetry-breaking instability. They can be either periodic or localised in space. Localised vegetation patterns consist of more or less circular spots or patches that can be either isolated or randomly distributed in space. We report on a striking patterning phenomenon consisting of localised vegetation labyrinths. This intriguing pattern is visible in satellite photographs taken in many territories of Africa and Australia. They consist of labyrinths which is spatially irregular pattern surrounded by either a homogeneous cover or a bare soil. The phenomenon is not specific to particular plants or soils. They are observed on strictly homogenous environmental conditions on flat landscapes, but they are also visible on hills. The spatial size of localized labyrinth ranges typically from a few hundred meters to ten kilometres. A simple modelling approach based on the interplay between short-range and long-range interactions governing plant communities or on the water dynamics explains the observations reported here.

Adolescence is a critical period in the consolidation of healthy lifestyles that can last into adulthood. To analyze changes in food consumption and eating behaviors in high-school adolescents during the first confinement, a cross-sectional study was conducted at the end of confinement in Spain. Changes in the frequency or quantity of consumption of different types of food and food-related behaviors were analyzed. Socioeconomic and health-related variables were also considered. To determine whether dietary changes were related to socioeconomic position (SEP), Poisson regression models with robust variance were estimated. Overall, there were some changes towards a healthier diet such as an increase in fruit consumption (38.9%) and a decrease in the consumption of soft drinks (49.8%), sweets and pastries (39.3%), and convenience foods (49.2%). Some changes, however, were related to less healthy behaviors, such as a more irregular pattern of meal distribution (39.9%) or an increase in snacking between meals (56.4%). Changes towards less healthy eating were also related to students’ SEP. The risk of worsening the diet was found to be 21% higher in adolescents from a more disadvantaged SEP. Future public policies could be adapted to avoid increasing nutritional and health inequalities.

In this paper, the anti-glare characteristics of strengthened glass used in the dashboard of automobiles were improved to enhanced the ability of the driver to read the display. To this end, the glass surface was etched with a solution containing HF as a main component. We adjusted the concentration of the etching solution and the etching time as variables, and the transmittance, gloss, haze value, etc. of the etched glass were measured. On the etched glass surface, an irregular pattern mainly containing dioxonium hexa-fluorosilicate crystal phases was generated, and controlling the pattern could improve the anti-glare characteristics of the glass. With higher concentration of the etching solution and longer etching time, the light transmittance, reflectance, and gloss of the etched glass were accordingly lower, while the haze value increased. We discussed the relationship between these property changes and the surface microstructure, pattern components, and roughness of the etched glass.

Abstract Chronic traumatic encephalopathy (CTE) is a neurodegenerative disorder associated with exposure to head trauma. In 2015, a panel of neuropathologists funded by the NINDS/NIBIB defined preliminary consensus neuropathological criteria for CTE, including the pathognomonic lesion of CTE as “an accumulation of abnormal hyperphosphorylated tau (p-tau) in neurons and astroglia distributed around small blood vessels at the depths of cortical sulci and in an irregular pattern,” based on review of 25 tauopathy cases. In 2016, the consensus panel met again to review and refine the preliminary criteria, with consideration around the minimum threshold for diagnosis and the reproducibility of a proposed pathological staging scheme. Eight neuropathologists evaluated 27 cases of tauopathies (17 CTE cases), blinded to clinical and demographic information. Generalized estimating equation analyses showed a statistically significant association between the raters and CTE diagnosis for both the blinded (OR = 72.11, 95% CI = 19.5–267.0) and unblinded rounds (OR = 256.91, 95% CI = 63.6–1558.6). Based on the challenges in assigning CTE stage, the panel proposed a working protocol including a minimum threshold for CTE diagnosis and an algorithm for the assessment of CTE severity as “Low CTE” or “High CTE” for use in future clinical, pathological, and molecular studies.

AbstractThe MW 8.8 Maule earthquake is the largest well-recorded megathrust earthquake reported in South America. It is known to have had very few foreshocks due to its locking degree, and a strong aftershock activity. We analyze seismic activity in the area of the 27 February 2010, MW 8.8 Maule earthquake at different time scales from 2000 to 2019. We differentiate the seismicity located inside the coseismic rupture zone of the main shock from that located in the areas surrounding the rupture zone. Using an original spatial and temporal method of seismic comparison, we find that after a period of seismic activity, the rupture zone at the plate interface experienced a long-term seismic quiescence before the main shock. Furthermore, a few days before the main shock, a set of seismic bursts of foreshocks located within the highest coseismic displacement area is observed. We show that after the main shock, the seismic rate decelerates during a period of 3 years, until reaching its initial interseismic value. We conclude that this megathrust earthquake is the consequence of various preparation stages increasing the locking degree at the plate interface and following an irregular pattern of seismic activity at large and short time scales.

Abstract. Kalsum U, Susanto S, Junaedi A, Khumaida N, Purnawawati H. 2021. Flowering and fruit quality characteristics in some seeded and seedless pummelo cultivars. Biodiversitas 22: 379-386. Most of the pummelo cultivars with seeds, while other parts of it are seedless. Each cultivar is thought to have his characteristics. This study aimed to obtain more detailed information related to the difference in flowering characteristics and fruit quality of seeded and seedless pummelo cultivars. This experiment used a randomized block design with four treatments, i.e., seeded pummelo (Adas Duku and Bali Merah 1) and seedless pummelo (Bali Merah 2 and Jawa 1). The results showed an irregular pattern in the flowering and harvesting period in both the seeded and seedless groups. Adas Duku blooms twice whereas Bali Merah 1 and the two cultivars of the seedless group bloom only once a year. The highest total flower number from the four cultivars was Adas Duku and followed by Jawa 1>Bali Merah 1>Bali Merah 2. Seeded pummelo was not significant difference with seedless pummelo on several variables, except the total titrable acidity (TTA) content (seeded group > seedless group). Adas Duku became the best cultivar compared to the other three cultivars in several characteristics, such as the lowest peel thickness, the highest in the edible portion, the total soluble solids (TSS) and TTA of flesh fruit.
