Effect of bromhexine on clinical outcomes and mortality in COVID-19 patients: A randomized clinical trial

Introduction: Bromhexine is a potential therapeutic option in COVID-19, but no data from a randomized clinical trial has been available. The present study aimed to evaluate the efficacy of bromhexine in intensive care unit (ICU) admission, mechanical ventilation, and mortality in patients with COVID-19. Methods: An open-label randomized clinical trial study was performed in Tabriz, North-West of Iran. They were randomized to either the treatment with the bromhexine group or the control group, in a 1:1 ratio with 39 patients in each arm. Standard therapy was used in both groups and those patients in the treatment group received oral bromhexine 8 mg three times a day additionally. The primary outcome was a decrease in the rate of ICU admissions, intubation/mechanical ventilation, and mortality. Results: A total of 78 patients with similar demographic and disease characteristics were enrolled. There was a significant reduction in ICU admissions (2 out of 39 vs. 11 out of 39, P = 0.006), intubation (1 out of 39 vs. 9 out of 39, P = 0.007) and death (0 vs. 5, P = 0.027) in the bromhexine treated group compared to the standard group. No patients were withdrawn from the study because of adverse effects. Conclusion: The early administration of oral bromhexine reduces the ICU transfer, intubation, and the mortality rate in patients with COVID-19. This affordable medication can easily be administered everywhere with a huge positive impact(s) on public health and the world economy. Altogether, the verification of our results on a larger scale and different medical centers is strongly recommended. Trial Registration: IRCT202003117046797N4; https://irct.ir/trial/46969.
Phylogeny of the Nudibranchia

More than 100 morphological, anatomical and histological characters pertaining to the Nudibranchia are discussed in the course of a phylogenetic analysis. Based on our own investigations on anatomy, histology and published literature, the polarity of each character is assessed by comparing its expression with outgroups, chiefly the Pleurobranchoidea, but also with other opisthobranch taxa (Cephalaspidea, Anaspidea, Sacoglossa), and ultimately with the Pulmonata, Vetigastropoda and Caenogastropoda. By extracting 46 applicable characters expressed in 30 taxa, a phylogenetic analysis of the major groups of the Nudibranchia is performed by using the computer program PAUP. Nudipleura new taxon (containing the Pleurobranchoidea plus Nudibranchia) is defined. The monophyly of the Nudibranchia, the Anthobranchia (containing the Bathydoridoidea plus Doridoidea), and the Cladobranchia (containing the Dendronotoidea plus Aeolidoidea and ‘Arminoidea’) are confirmed and autapomorphies are highlighted. The paraphyly of the ‘Arminoidea’ is demonstrated. Incongruities at lower taxonomic level are discussed.
Preparatory Learners’ Perspectives of Learner Autonomy in the Saudi Context

Learner autonomy is a developing concept that has been the focal point of number of research papers investigating language learning. It has been under investigation by number of scholars and researchers over the years, the concept of learner autonomy has been supported by number of researchers, others attempted to prove that it does not fit all learners of different backgrounds. In this research paper, the focus is mainly on learners’ perspectives of learner autonomy, what do they know? To what extent the students understand the concept of learner autonomy? Developing autonomous learners is an area that needs to be explained. There are limited studies conducted in the Saudi context therefore, this study investigates Preparatory year female EFL students’ perspectives of learner autonomy in the Saudi context. Moreover, it examines whether the learners have the knowledge and the competence to develop their learning. The perspectives and views of 150 learners were collected using a questionnaire. The study follows a mixed methods approach. The reviewed literature showed that implications of learner autonomy reflected positively on learners (Burkert & Schwienhorst. 2008; Han, 2015). The main findings of this study revealed that students participated in this study had negative perspective of learner autonomy
Diethanolamine: An Inhibitor of Mild Steel Corrosion in Cassava Fluid Extract

The effect of diethanolamine on the corrosion inhibition of mild steel in cassava fluid was investigated by weight loss measurements. The investigation was conducted at temperatures of 298K and 333K at concentration of 0.5M, 1.0M, 1.5M and 2.0M concentrations of diethanolamine in cassava fluid. The results showed that weight loss recorded decreased with concentration and temperature. Weight loss decrease from 0.0503mm, blank solution to 0.0101mm in 2.0M concentration at 298K and a decrease in corrosion rate of 0.0789mm/yr to 0.0411mm/yr under the same conditions on the 3 day. Weight loss also decreased from 0.0243mm blank solution to 0.0002mm in 2.0M concentration and corrosion rate also decreased from 0.0380mm/yr to 0.0003mm/yr under the same concentration at 333K, on the 3 day. Further decrease was also recorded as the day progresses to the 9 day. The highest efficiencies recorded were 98.01% at 0.5M concentration at 298K and 9918% at 2.0M concentration at 333K. The recorded values showed that diethanolamine is an efficient corrosion inhibitor of mild steel in
Growth Attributes of Kalmegh [Andrographis paniculata (Burm.f.) Wall Nees] as influenced by integrated nutrient management under Tarai conditions of Uttarakhand

Medicinal and Aromatic plants form a numerically large group of economically important plants which provide basic raw materials for medicines, perfumes, flavours and cosmetics etc. Kalmegh is an important medicinal plant. It has been effectively used in traditional Asian medicines. A field experiment was conducted during kharif season of 2017 & 2018 at Medicinal Plants Research and Development Centre (M. R. D. C) of G. B. Pant University of Agriculture & Technology, Pantnagar (Uttarakhand) to study the effect of application of Organic and different doses of Nitrogen on growth attributes viz: Plant height (cm), number of branches per plant, Number of leaves per plant and dry matter accumulation (g/m) of Kalmegh. Results revealed that, among, application of different organic manures, higher growth attributes were recorded in the plots treated with Vermicompost @ 5 t/ha over poultry manure @ 5 t/ha & no organic manure application (Control) while among application of different Nitrogen doses, increasing growth trend of kalmegh was observed in the plots treated with 75 (37.5+37.5) Kg N/ha in to 2 splits (First as basal and second as top dress at 25 DAT) and 75 kg N as basal followed by 50 and 0 kg nitrogen per hectare with same P and K.
Learning Travel Time Distributions with Deep Generative Model

Travel time estimation of a given route with respect to real-time traffic condition is extremely useful for many applications like route planning. We argue that it is even more useful to estimate the travel time distribution, from which we can derive the expected travel time as well as the uncertainty. In this paper, we develop a deep generative model - DeepGTT - to learn the travel time distribution for any route by conditioning on the real-time traffic. DeepGTT interprets the generation of travel time using a three-layer hierarchical probabilistic model. In the first layer, we present two techniques, amortization and spatial smoothness embeddings, to share statistical strength among different road segments; a convolutional neural net based representation learning component is also proposed to capture the dynamically changing real-time traffic condition. In the middle layer, a nonlinear factorization model is developed to generate auxiliary random variable i.e., speed. The introduction of this middle layer separates the statical spatial features from the dynamically changing real-time traffic conditions, allowing us to incorporate the heterogeneous influencing factors into a single model. In the last layer, an attention mechanism based function is proposed to collectively generate the observed travel time. DeepGTT describes the generation process in a reasonable manner, and thus it not only produces more accurate results but also is more efficient. On a real-world large-scale data set, we show that DeepGTT produces substantially better results than state-of-the-art alternatives in two tasks: travel time estimation and route recovery from sparse trajectory data.
Quantitative dynamic modelling of basin development in the central and eastern North Sea region – coaxial stretching and strain localization

A new two-dimensional dynamic lithosphere model is used to simulate the Late Palaeozoic to end Danian evolution of the Norwegian-Danish Basin and the post Permian evolution of the Central North Sea including the Central Graben. The transient heat equation and the equations of motion are solved using the finite element method. The lithosphere deforms by brittle and ductile processes through an elasto-visco-plastic rheology depending on temperature, pressure, strain-rate and material parameters. Strain softening dependent on accumulated strain is incorporated. Deposition, erosion and compaction of sediments are simulated. Results show that it is possible to satisfy observations of crustal structure, sediment thickness and surface heat flow for both basins taking all major tectonic and thermal events into consideration. The evolution of the Norwegian-Danish Basin is modelled using a Late Carboniferous – Early Permian thermal event, main rift phase in Early Permian and a minor extensional phase in Triassic. For the Central North Sea two thermal and three tectonic events are simulated: Late Carboniferous – Early Permian and Middle Jurassic thermal events, Early Triassic and Late Jurassic extension, and Late Cretaceous compression. Results show that strain softening may lead to strain localization during extension and therefore may explain observations of upper mantle dipping reflectors in the North Sea. A pure shear dominated extensional regime may change into a simple shear system.
MODAL ANALYSIS OF SELF-ALIGNING BALL BEARING USING FEA – A REVIEW

This paper presents state of art of review on self-aligning ball bearing using FEA. The moving bearing, with external ring fixed, is a multi-body mechanical framework with moving components that transmit movement and burden from the inward raceway to the external raceway. Present day pattern of Dynamic examination is helpful in the early forecast; reproduction of rotor bearing framework as the assembling of the model is tedious, expensive, and required further investigation for weariness disappointment. The dynamic examination has turned into an exceptionally useful asset for the improvement of the real execution of the framework. The approach for expectation and approval of dynamic attributes of bearing rotor framework vibration is contemplated. Solid works and ANSYS programming are the promising devices for the displaying and modular investigation of the bearing rotor framework.
Planting density, and nitrogen and phosphorus fertilization effect on different bread wheat (Triticum aestivum L.) genotypes in Southern Tigray, Ethiopia

Optimum seeding rate and nitrogen (N) and phosphorus (P) fertilization are the most important production factors for higher grain yield. Indiscriminate use of seeding rates and N and P fertilization does not only increase production costs but usually decrease wheat grain yield. Study on the interaction effect of planting density and N and P-fertilizer levels on bread wheat varieties was conducted in 2014 cropping season on vertisols of Ofla and Emba-Alaje districts of southern Tigray, Ethiopia with the objective of determining the optimum plant density and optimum N and P fertilization for different Wheat genotypes. The experiment contained split-split plot design on which three recently released bread Wheat varieties (Mekelle 3, Mekelle 4 and Danda’a) were assigned as a main plot, Four level of N/P205 combination (46/46, 92/69, 115/92 and 138/115 kg N/P205 ha -1 ) arranged in a sub plot and four levels of planting density (150, 300, 400 and 500 plant/m 2 ) assigned as sub-sub plot factor and replicated three times. The analysis of variance indicate that variety, fertilizer, planting density, variety x fertilizer, variety x planting density, fertilizer x planting density, and variety x fertilizer x planting density interaction, have significant (P<0.05) effect on grain yield of bread Wheat varieties. Nitrogen and phosphorus fertilizers and variety showed significance (P<0.05) effect on biomass yield, seeds per spike, effective tiller number and plant height. Grain yield, plant height, effective tiller number/m 2 and biomass yield of bread wheat variety increase linearly with planting density and N/P205 fertilizer rate. More grain (6.93 and 5.21 t/ha) for Emba-Alaje and Ofla, respectively was recorded from the interaction effects of 138/115 kg of N/P205 ha -1 with 300 plant/m 2 planting density for variety Mekelle-3. However, 115/92 kg of N/P205 ha -1 with planting density of 500 plants/m 2 reached higher economical return (MRR=3166.12).
The recently established diatom Coscinodiscus wailesii (Coscinodiscales, Bacillariophyta) in Brazilian waters. I: Remarks on morphology and distribution

Coscinodiscus wailesii Gran et Angst is a large centric diatom (280–500 μm diameter) from marine phytoplankton, characterized by a cylindrical frustule with flat valvar surface, two marginal rings of rimoportulae on the mantle, and two macrorimoportulae. Cells from cultured and natural populations collected in Paranaguá Bay, Paraná, southern Brazil were observed under light and scanning electron microscopes to verify the populations’ correct identity and morphology. In both populations, a typical central rosette or a hyaline area was found in the valvar center. The species’ distribution in Brazilian waters was revised, and a discussion on possible vectors of transport was made. Blooms of the species occur sporadically in the coast of Paraná, seeming to affect the local trophic chain.
Potability of Drinking Water in an Oil Impacted Community in Southern Nigeria

Microbiological and physicochemical analyses of borehole water samples from Eastern Obolo Local Government Area of Akwa Ibom State were conducted to ascertain their potability. Seven bacterial species were isolated and identified. These included Bacillus subtilis, Enterococcus faecalis, Staphylococcus aureus, Clostridium perfringens, Pseudomonas aeruginosa, Micrococcus varians and Escherichia coli . The viable bacterial count ranged from 5.2x10 4 cfu/ml to 15x10 4 cfu/ml while the total coliform count of the water samples ranged from 2 cfu/100ml to 51 cfu/100ml. The most frequently occurring bacterium was Enterococcus faecalis (22%) while Escherichia coli was the least (7%). Some physicochemical parameters like iron and mercury in some boreholes did not meet World Health Organization (WHO) standard for potable water. High counts of indicator bacteria also constitute a threat to public health. Journal of Applied Sciences and Environmental Management Vol. 9(1) 2005: 135-141
A Model-Based Evaluation of Active Management of Recreational Fishing Effort

Abstract Recreational fisheries are increasingly faced with the dilemma of “too many people chasing too few fish. ” Active management of angler effort promises relief from the pressures of overcrowding and declines in angling quality. In this paper, we develop a regional-scale model of recreational fishery dynamics to evaluate how active effort management policies might affect the cumulative value taken over many fisheries. The model incorporates linear increases in satisfaction per angler-day with increases in catch rate to represent demand, declines in catch rate with increasing effort to represent supply limitations, and angler movement among open-access fisheries to represent the presence of uncontrolled, open-access alternatives to effort-managed fisheries. The management control variables were the proportion of fisheries managed under effort control (P m) and the proportion of open-access effort allowed on managed lakes (P e). Unmanaged lakes remained open access. Policies that maximized total region.
Effects of Zinc Methionine Complex on Milk Production and Somatic Cell Count of Dairy Cows: Twelve-Trial Summary

The objective of this review was to summarize 12 trials (13 comparisons) evaluating effects of zinc methionine (ZM) complex (ZINPRO®; Zinpro Corporation, Eden Prairie, MN) on lactation performance and udder health. Summarized trials were conducted in Washington (2), Colorado (2), New York, Illinois, Arkansas, Missouri, Georgia, Great Britain, Germany, and Israel. In 5 of the trials, ZM provided between 180 and 200 mg of zinc/d per head; in the remaining 7 trials (8 comparisons), ZM supplied 360 to 400 mg of zinc. In all diets, cows received additional zinc from inorganic sources, with the exception of the control diet in one of the Missouri comparisons. For statistical evaluation, each trial was considered as a block, and the treatment least squares mean within a trial was treated as an observation using a mixed model. Cows fed ZM produced more (P 0.15) between treatment and control cows. Somatic cell count (SCC; 1000/mL) was reduced from 294 to 196 (P<0.01) in cows receiving ZM. This summary of 12 dairy trials indicates that ZM increases lactation performance and improves udder health, as a 33.3% reduction in SCC occurred.
Effect of Weed Removal on Productivity of Chickpea (Cicer arietinum L.) and Lentil (Lens culinaris Med.) in a Mediterranean Environment

Three field experiments were conducted on chickpea (Cicer arietinum L.) and four on lentil (Lens culinaris Med.) at different winter-sown rainfed locations in Jordan from 1988/89 to 1990/91 to study the effect of the duration of weed-free and weed-infested conditions on yields and yield components of the crops. Chickpea seed yields were reduced on average by 81 % and straw yields by 63 % when fields remained weed infested until harvest compared with weed-free conditions throughout the growing season. The corresponding lentil seed and straw yield decreases were 63 % and 55 %. As the duration of weed-free period increased and the duration of weed-infested period decreased, yields increased. However, the critical period of weed interference was between 35 and 49 days after emergence in chickpea and between 49 and 56 days after emergence in lentil, when these crops were at an advanced stage of vegetative growth. There were significant negative correlations between the weed dry weight and the seed or straw yields. The reduction in seed yields in both crops because of weed interference occurred mainly through the reduced number of pods /plant, which in turn was partly the result of reduced number of secondary branches. In chickpea, some reduction also occurred through reduced 100-seed weight.
Endruweit, Andreas and Zeng, X. and Matveev, Mikhail Y. and Long, Andrew C. (2018) Effect of yarn cross- sectional shape on resin flow through inter-yarn gaps in textile reinforcements. Composites Part A: Applied

Axial flow through gaps between aligned straight yarns with realistic cross-sectional shapes, described by power-ellipses, was analysed numerically. At a given fibre volume fraction, equivalent gap permeabilities have a maximum at minimum size of elongated tapering parts of the gap cross-section and a ratio of gap width to height near 1. When the yarn spacing is given in addition to the fibre volume fraction, calculated maximum and minimum values for the equivalent permeability of inter-yarn gaps, which occur at nearrectangular and lenticular cross-sections, differ by factors of up to 3.3. Novel approximations for the shape factor and the hydraulic diameter in Poiseuille flow were derived as a function of the fibre volume fraction, the yarn cross-sectional aspect ratio and the geometrical parameter describing the shape of the power-elliptical yarn cross-section. This allows the equivalent gap permeability to be predicted with good accuracy for any fibre volume fraction and yarn cross-section. 2017 The Authors. Published by Elsevier Ltd.

CO2 and HCO3 ߚ uptake in marine diatoms acclimated to different CO2 concentrations

Rates of cellular uptake of CO2 and HCO3− during steadyߚstate photosynthesis were measured in the marine diatoms Thalassiosira weissflogii and Phaeodactylum tricornutum, acclimated to CO2 partial pressures of 36, 180, 360, and 1,800 ppmv. In addition, in vivo activity of extracellular (eCA) and intracellular (iCA) carbonic anhydrase was determined in relation to CO2 availability. Both species responded to diminishing CO2 supply with an increase in eCA and iCA activity. In P. tricornutum, eCA activity was close to the detection limit at higher CO2 concentrations. Simultaneous uptake of CO2 and HCO3− was observed in both diatoms. At airߚequilibrated CO2 levels (360 ppmv), T. weissflogii took up CO2 and HCO3− at approximately the same rate, whereas CO2 uptake exceeded HCO3− uptake by a factor of two in P. tricornutum. In both diatoms, CO2 :HCO3− uptake ratios progressively decreased with decreasing CO2 concentration, whereas substrate affinities of CO2 and HCO3− uptake increased. Halfߚsaturation concentrations were always <=5 mM CO2 for CO2 uptake and <700 mM HCO3− for HCO3− uptake. Our results indicate the presence of highly efficient uptake systems for CO2 and HCO3− in both diatoms at concentrations typically encountered in ocean surface waters and the ability to adjust uptake rates to a wide range of inorganic carbon supply.
