Calving of a Large Greenlandic Tidewater Glacier has Complex Links to Meltwater Plumes and Mélange

Calving and solid ice discharge into fjords account for approximately half of the annual net ice loss from the Greenland ice sheet, but these processes are rarely observed. To gain insights into the spatiotemporal nature of calving, we use a terrestrial radar interferometer to derive a 3‐week record of 8,026 calving events from Sermeq Kujalleq (Store Glacier, West Greenland), including the transition between a mélange‐filled and ice‐free fjord. We show that calving rates double across this transition and that the interferometer record is in good agreement with volumetric estimates of calving losses from contemporaneous unmanned aerial vehicle surveys. We report significant variations in calving activity over time, which obfuscate any simple power‐law relationship. While there is a statistically significant relationship between surface melt and the number of calving events, no such relationship exists between surface melt and the volume of these events. Similarly, we find a 70% increase in the number of calving events in the presence of visible meltwater plumes but only a 3% increase in calving volumes. While calving losses appear to have no clear single control, we find a bimodal distribution of iceberg sizes due to small blocks breaking off the subaerial part of the glacier front and large capsizing icebergs forming by full‐thickness failure. Whereas previous work has hypothesized that tidewater glaciers can be grouped according to whether they calve predominantly by the former or latter mechanism, our observations indicate that calving here inherently comprises both and that the dominant process can change over relatively short periods.
Evidence for Ti Interstitial Induced Extended Visible Absorption and Near Infrared Photoluminescence from Undoped TiO2 Nanoribbons: An In Situ Photoluminescence Study

Despite decades of research on the role of intrinsic defects in enhancing the performance of reduced TiO2 based materials, unambiguous identification of defects responsible for visible light absorption, and near-infrared (NIR) photoluminescence from undoped TiO2 has remained challenging. Herein, through in situ photoluminescence (PL) studies under a controlled environment, we investigated the origin of an extended visible absorption, visible and NIR PL emission from undoped TiO2 nanoribbons grown by a solvothermal route. Our studies reveal that oxygen vacancies, Ti3+, and F+ center in TiO2 are responsible for absorption in the violet and blue-green region and the PL emission in the visible region. On the other hand, absorption in the yellow-red to NIR region and PL emission in the NIR region at 1.47 and ∼1.30 eV are due to Ti4+ and Ti3+ interstitials, respectively, near the surface identified for the first time. The above conclusions are supported by electron paramagnetic resonance and X-ray photoelectron.
Career ready?

The focus of this working paper is on how secondary schools can optimise young people’s preparation for adult employment at a time of extreme labour market turbulence. By reviewing academic analysis of national longitudinal datasets, it is possible to identify indicators of comparative adult success. How teenagers (i) think about their futures in work and what they do to (ii) explore and (iii) experience workplaces within and outside of schools is consistently associated with better than expected employment outcomes in adulthood. Data-driven career guidance will take such indicators into account within delivery. Analysis of the Programme for International Student Assessment (PISA) 2018 illustrates substantial variation in the extent of such career readiness between and within countries. Variation in career readiness is particularly associated with disadvantage. More effective education systems will ensure schools systematically address inequalities in teenage access to information and support in preparing for working life.
Safety and Efficacy of Novel Epidural Clonidine Micropellets for Lumbosacral Radiculopathy

Background: Chronic back and leg pain is a leading cause of disability and results in a significant health care expenditure. Options such as physical therapy, corticosteroids Epidural Injections (ESI) or spine surgery have limited long term benefit and may cause significant morbidity. Clonidine has anti-neuropathic pain and anti-inflammatory properties. A novel, slow-release biodegradable polymer (Poly (D, L-lactide) clonidine micropellets deliver sustained, high clonidine levels and may provide prolonged pain relief with minimal systemic side effects. Methods: A pilot multicenter investigation of the safety, pharmacokinetics (PK) and effectiveness of clonidine micropellets in patients with chronic lumbosacral radiculopathy. Three sequential cohorts of 18 subjects each received a single epidural injection of clonidine 0.325 mg, 0.975 mg or 1.95 mg (1, 3 or 6 micropellets, respectively) at the interlaminar epidural level that corresponds to the painful dermatomes. Clonidine PK was evaluated at multiple time points for 84 days. Paired t-tests were performed to examine changes from baseline within each cohort, and analysis of covariance evaluated differences between dose levels. NRS and RMS-Q disability scores were recorded at baseline and for one year follow up. Results: Peak plasma clonidine was observed 24h after injection and the mean elimination half-life ranged from 13 to 20 days. Statistically significant reduction in leg and back pain from baseline at all-time points up to 1 year was observed, in all cohorts as well as significant improvement in the RMS-Q at all timepoints. Adverse events and rescue medications were also recorded. Conclusion: Clonidine Micropellets would safely and slowly deliver clonidine over a prolonged period. Clonidine’s anti-neuropathic and anti-inflammatory effects could treat the radicular back and leg pain.

Etiquette failure of the speech as a linguoecological problem

the French word "etiquette" means "label". This concept is regarded as a philosophical, ethical, and linguistic and cultural notion. And the failure of etiquette in speech is a great problem of communication. As everybody knows, etiquette, including speech, is a set of rules of behavior that are associated with the external manifestation of attitudes to people. The external manifestation usually shows the inner essence of the relationship, which should naturally be mutually polite and kind. But the fact that etiquette has a national character, has its own cultural characteristics, takes it beyond the scope of one science. The study of speech etiquette needs special attention because it stands at the intersection of linguistics, cultural theory and history, ethnography, country studies, psychology, and other disciplines. Here, we will consider etiquette from the point of view of linguoecology as an obligatory component of linguoculturology.

(2) According to the motivation, there are four types of tourists: seeking knowledge and health and wellness, facility service and environmental experience, exploration and reflection, and nearby travel. (3) There are significant differences among the four different types of health and wellness tourists in age, education level, occupation and monthly income.
Existence results for fractional impulsive delay feedback control systems with Caputo fractional derivatives

The goal of this paper is to provide systematic approaches to study the feedback control systems governed by fractional impulsive delay evolution equations involving Caputo fractional derivatives in separable reflexive Banach spaces. This work is a continuation of previous work. We firstly give an existence result of mild solutions for the equations by applying the Banach's fixed point theorem and the Leray-Schauder alternative fixed point theorem. Next, by using the Filippove theorem and the Cesari property, we obtain the existence result of feasible pairs for the feedback control system. Finally, some applications are given to illustrate our main results.
Removal Of Copper(II) From Aqueous SolutionBy Non-living Oscillatoria Sp.

The performance of dried green alga Oscillatoria sp. to remove Cu(II) from aqueous solution was investigated as a biosorbent. The non-living algal biomass was found to remove copper ions efficiently. The rate of biosorption was affected by contact time, pH, initial copper ion concentration and temperature. Optimal initial pH for Cu(II) sorption was found to be 4. The uptake of Cu(II) by algal biomass is very rapid in the initial contact time. Metal uptake capacity was observed to be increasing with an increase in initial metal ion concentrations. Temperature has a positive effect on the biosorption of the copper by Oscillatoria sp. The experimental data fitted well in both the Freundlich and Langmuir isotherms (R2>0.98). Qmax obtained from the Langmuir isotherms was found to be 36.2 mg/g. The sorbed copper ions were effectively desorbed using 0.1N HCl.

COVID-19 and the Stock Market

When disaster strikes, the weak suffer mightily, the strong only slightly. That is the lesson from stock market reactions to COVID-19. Strong firms had a robust financial position, advanced environmental and social performance, and were not severely exposed to social distancing and lockdowns. Firms with significant international exposure suffered more, at least at first. The ultimate effects of policy interventions, including those by central banks, have yet to be revealed. The market recovery in the second quarter of 2020 is like a patient recovering from COVID-19: hopeful but still uncertain. Managers and policymakers should project the future with great caution.

COMPARATIVE STUDY BETWEEN EFFECTIVENESS OF GLIBENCLAMIDE VERSUS INSULIN IN MANAGEMENT OF GESTATIONAL DIABETES

Background: Gestational diabetes mellitus (GDM) offers an important opportunity for diagnosis and implementation of clinical strategies for diabetes prevention. Objective: To evaluate the effectiveness of glibenclamide versus insulin in the management of GDM in second half of pregnancy. Patients and methods: This experimental prospective comparative study was carried out. A total of 100 women aged below 35 years were included in the study from those attending the Outpatient Clinic of Obstetrics and Gynecology Department of Al-Ahrar Teaching Hospital in Zagazig, Egypt, through the period from July 2017 to March 2020, and they were randomly allocated and divided into two groups 50 patients in each. The first group (A) received glibenclamide at an oral dose of 2.5-5 mg once or twice a day with a maximum dose of 10 mg/day and the second group (B) received standard insulin mixtard therapy. Dosing was based upon subcutaneous two shot combined dose of intermediate acting and short-acting insulin given prior to breakfast and dinner. The starting dose was 0.7 units per kilogram of the body weight at admission and increased weekly as necessary. Results: The delivery type was comparable in both groups, 28% of women underwent vaginal delivery in glibenclamide group, and 22% of women underwent vaginal delivery in insulin group. 72% and 78% of women underwent cesarean section in glibenclamide and insulin groups respectively. The gestational age at delivery was comparable in both groups. Conclusion: Glibenclamide seem to be a simple, safe, inexpensive and attractive alternative to insulin for the treatment of gestational diabetes mellitus.
A Brief Review on Structural Health Monitoring Sensor Technology in Civil and Aviation Technology Applications

The Structural Health Monitoring (SHM) system is a method for evaluating and monitoring the integrity of the structure. It has been widely used in various engineering sectors, such as in aerospace, civil and energy sectors due to its ability to react to structural changes on an online basis or in real-time monitoring. The SHM system was able to evolve and work in a variety of structures or components due to the rapid development of sensor technology. It is believed that SHM will become an important tool in various industries for structural monitoring in future years. The paper presents a summary of the latest SHM technology in civil and aviation technology applications as well as the challenges in cost analysis and certification issues for the implementation of SHM.
Targeted Delivery of LM22A-4 by Cubosomes Protects Retinal Ganglion Cells in an Experimental Glaucoma Model

Glaucoma, a major cause of irreversible blindness worldwide, is associated with elevated intraocular pressure (IOP) and progressive loss of retinal ganglion cells (RGCs) that undergo apoptosis. A mechanism for RGCs injury involves impairment of neurotrophic support and exogenous supply of neurotrophic factors has been shown to be beneficial. However, neurotrophic factors can have widespread effects on neuronal tissues, thus targeting neurotrophic support to injured neurons may be a better neuroprotective strategy. In this study, we have encapsulated LM22A-4, a small neurotrophic factor mimetic, into Annexin V-conjugated cubosomes (L4-ACs) for targeted delivery to injured RGCs in a model of glaucoma, which is induced by acute IOP elevation. We have tested cubosomes formulations that encapsulate from 9% to 33% LM22A-4. Our data indicated that cubosomes encapsulating 9% and 17% LM22A-4 exhibited a mixture of Pn3m/Im3m cubic phase, whereas 23% and 33% showed a pure Im3m cubic phase. We found that 17% L4-ACs with Pn3m/Im3m symmetries showed better in-situ and in-vitro lipid membrane interactions than the 23% and 33% L4-ACs with Im3m symmetry. In vivo experiments showed that 17% L4-ACs targeted the posterior retina and the optic nerve head, which prevented RGCs loss in a mouse model of acute IOP elevation. These results provide evidence that cubosomes-based LM22A-4 delivery may be a useful targeted approached to prevent the progression of RGCs loss in glaucoma.

The living banana plant as a long-lasting battery cell

ABSTRACT Among citrus fruits, lemon is widely used as a low-power electrical source. Although, it can generate a potential difference, this phenomenon is only sustainable for few days, and no other alternative organism has been reported to provide a similar potential with longer duration. This study reports the discovery of living banana plant as an inexpensive, reliable, stable, and long-lasting power. A Zn anode and Cu cathode are inserted into banana plant to extract electricity, and the organic compounds of plant act as electrolyte. This new discovery may introduce an era of providing renewable energy to who live in proximity to banana plantations.
Swelling and Thermoresponsive Behavior of Linear versus Cyclic Poly(N-isopropylacrylamide) Thin Films

Polymer topology and reduced dimensions can have a significant impact on the properties and phase transitions of polymeric films with thicknesses below a few hundred nanometers. We study the impact of these effects in the case of thin films of cyclic and linear poly(N-isopropylacrylamide) (PNIPAM) exposed to water vapor. Specifically, we monitor the swelling kinetics of the thin PNIPAM films, their interfacial interactions, and their LCST-type demixing phase transition, using white light interferometry and X-ray reflectivity. As the film thickness decreases, the swelling ratio increases, presumably due to the increasingly dominant effect of polymer/substrate interactions. The time constants of the swelling process depend on both the film thickness and the PNIPAM topology. Consistent with earlier observations for PNIPAM solutions, in thin swollen films of comparable concentration, cyclic PNIPAM exhibits a broader and thus less cooperative demixing transition than the linear PNIPAM counterpart.
Eco-evolutionary spatial dynamics of non-linear social dilemmas

Spatial dynamics can promote the evolution of cooperation. While dispersal processes have been studied in simple evolutionary games, real-world social dilemmas are much more complicated. The public good, in many cases, does not increase linearly as per the investment in it. When the investment is low, for example, every additional unit of the investment may help a lot to increase the public good, but the effect vanishes as the number of investments increase. Such non-linear behaviour is the norm rather than an exception in a variety of social as well as biological systems. We take into account the non-linearity in the payoffs of the public goods game as well as the natural demographic effects of population densities. Population density has also been shown to impact the evolution of co-operation. Coupling these non-linear games and population size effect together with an explicitly defined spatial structure brings us one step closer to the complexity of real eco-evolutionary spatial systems. We show how the non-linearity in payoffs, resulting in synergy or discounting of public goods can alter the effective rate of return on the cooperative investment. Synergy or discounting in public goods accumulation affects the resulting spatial structure, not just quantitatively but in some cases, drastically changing the outcomes. In cases where a linear payoff structure would lead to extinction, synergy can support the coexistence of cooperators and defectors. The combined eco-evolutionary trajectory can thus be qualitatively different in cases on non-linear social dilemmas.
Automatic fiscal stabilisers: Recent evolution and policy options to boost their effectiveness

Building on the automatic fiscal stabilisers literature, this paper assesses how automatic stabilisers have evolved over the past two decades by analysing changes in the personal income tax and social benefit systems. In three-quarters of the 35 OECD countries analysed, indicators of the strength of automatic stabilisers (aggregate elasticities of household income after tax with respect to the cycle and aggregate net replacement rates) changed little or moderately over the past two decades, suggesting broadly stable automatic stabilisers of household disposable income. The paper discusses pros and cons of several policy options to strengthen automatic stabilisers in the current environment. The effectiveness and possible side effects, particularly related to disincentives to work, vary across policy options. Consequently, policy reform proposals should be carefully assessed in a country-specific context and take into account other important policy objectives of tax and benefit systems.
