Update on radiation protection of the thyroid gland.

In recent years, concern about the effects of ionizing radiation on exposed individuals has led to the need to regulate and quantify the use of diagnostic and therapeutic techniques. Geopolitical events in recent times have also increased the population's perception of insecurity regarding ionizing radiation, and we increasingly face patients reluctant to undergo certain types of scans in our nuclear medicine services and, albeit less frequently, in radiology services. This article aims to summarise the extent to which ionizing radiation is present in our daily lives and how diagnostic and therapeutic procedures can affect our health, particularly from the perspective of their effects on the thyroid gland, one of the body's most radiation-sensitive organs.

The Autocatalytic Chemical Reaction of a Soluble Biopolymer Derived from Municipal Biowaste.

The paper discusses the perspectives of further implementation of the autocatalytic properties of a soluble biopolymer (SBP) derived from municipal biowastes for the realisation of a biorefinery producing value-added bio-products for consumer use. The reaction of an SBP and water is reported to cause the depolymerisation and oxidation of the pristine SBP organic matter with the formation of carboxyl-functionalised polymers having lower molecular weight and CO. These findings demonstrate the oxidation of the SBP via water, which could only occur through the production of O and OH radicals catalysed by the SBP.

Mild Chemical Treatment of Unsorted Urban Food Wastes.

Municipal biowastes are conventionally treated by assessed anaerobic and aerobic fermentation to produce biogas, anaerobic digestate, and compost. Low-temperature hydrolysis and the oxidation of the digestate and compost, which are still at the experimental stage, are known to yield water-soluble value-added chemical specialities for use in different sectors of the chemical industry and in agriculture. The present paper reports the application of the two chemical reactions to the biowastes before fermentation.

How much does reducing inequality matter for global poverty?

The goals of ending extreme poverty by 2030 and working towards a more equal distribution of incomes are part of the United Nations' Sustainable Development Goals. Using data from 166 countries comprising 97.5% of the world's population, we simulate scenarios for global poverty from 2019 to 2030 under various assumptions about growth and inequality.

Aligning recycling behaviors and the recycling system - Towards a full cycle of materials and behavioral methods.

In a transdisciplinary project with the Municipality of Trelew (Argentina), we assessed barriers to households disposing of separated waste, developed supportive behavioral interventions, tested the interventions in a randomized controlled trial, and supported the Municipality in upscaling the most successful and cost-effective intervention to a total of 20,000 households. The interventions were designed to address the three main barriers to waste separation detected through a baseline study: a lack of knowledge on how separation works; the additional hassle it represents; and the self-regulation challenge it poses. The interventions consisted of envelopes containing simplifying information, empathetic messages, a magnetic calendar acting as a reminder, or a combination thereof.

Obesity and food away from home: What drives the socioeconomic gradient in excess body weight?

Rising obesity rates are one of the most challenging public health issues in many emerging economies. To what extent food away from home (FAFH) and its nutritional components are behind this rise is not yet well understood. To address the issue, this paper combines a representative restaurant survey that includes detailed information on the diet quality of the most widely consumed meals and their nutritional components from 1605 restaurants and a representative household survey with anthropometric measures of adult women living in 40 neighborhoods in the Lima Metropolitan Area.

Putting your money where your mouth is: Geographic targeting of World Bank projects to the bottom 40 percent.

The adoption of the shared prosperity goal by the World Bank in 2013 and Sustainable Development Goal 10, on inequality, by the United Nations in 2015 should strengthen the focus of development interventions and cooperation on the income growth of the bottom 40 percent of the income distribution. This paper contributes to the incipient literature on within-country allocations of development institutions and assesses the geographic targeting of World Bank projects to the bottom 40 percent. Bivariate correlations between the allocation of project funding approved over 2005-14 and the geographical distribution of the bottom 40 as measured by survey income or consumption data are complemented by regressions with population and other potential factors affecting the within-country allocations as controls.

A hierarchically patterned, bioinspired e-skin able to detect the direction of applied pressure for robotics.

Tactile sensing is required for the dexterous manipulation of objects in robotic applications. In particular, the ability to measure and distinguish in real time normal and shear forces is crucial for slip detection and interaction with fragile objects. Here, we report a biomimetic soft electronic skin (e-skin) that is composed of an array of capacitors and capable of measuring and discriminating in real time both normal and tangential forces.

Organo-clays and nanosponges for acquifer bioremediation: adsorption and degradation of triclopyr.

To avoid the problem of groundwater contamination, mitigation techniques have been proposed that consist of creating barriers made of suitable materials that can facilitate the adsorption and degradation of the pollutants. This study aims at evaluating the capacity of two organo-clays (Dellite 67 G and Dellite 43 B) and one nanosponge to adsorb the herbicide, triclopyr. Triclopyr was chosen because it is a good example of a moderately mobile, leacheable molecule.

Organically modified clays as binders of fumonisins in feedstocks.

This study reports an investigation on the ability of organically modified clays to bind mycotoxins, fumonisins B1 (FB1) and B2 (FB2). Organically modified clays are commercia materials prepared from natural clays, generally montmorillonite, by exchanging the inorganic cation with an ammonium organic cation. A screening experiment conducted on 13 organically modified clays and 3 nonmodified clays, used as controls, has confirmed that the presence of an organic cation in the clay interlayer promoted the adsorption of both fumonisins.
