Twenty-five years of observations of soil organic carbon in Swiss croplands showing stability overall but with some divergent trends

The temporal evolution of soil organic carbon (SOC) is of major importance given its status as a key parameter in many soil functions. Furthermore, soils constitute an important reservoir of carbon in our environment. In light of climate change, consistent SOC data over extended periods in combination with information on agricultural management are much required, but still scarce...

Contested EU trade governance: transparency conundrums in TTIP negotiations

During TTIP negotiations, the European Commission was severely criticized by civil society organizations and public opinion for its secrecy regarding negotiation strategies and priorities. The Commission responded by making some negotiating texts publicly available. This article explores the implications of increasing transparency in trade negotiations. Drawing on negotiation...

Overcoming the Challenges of Water, Waste and Climate Change in Asian Cities

Unprecedented challenges in urban management of water, waste and climate change—amplified by urbanisation and economic growth—are growing in Asia. In this circumstance, cities need to be aware of threats and opportunities to improve their capacity in addressing these challenges. This paper identifies priorities, barriers and enablers of these capacities. Through the City...

Election Law and White Identity Politics

The role of race in American politics looms large in several election law doctrines. Regrettably, though, these doctrines’ analyses of race, racial identity, and the relationships between race and politics often lack sophistication, historical context, or foresight. The political status quo is treated as race-neutral, when in fact it is anything but. Specifically, the doctrines...

Aktiv rekonfigurierbares Robotersystem zum Aufbau geschlossener Strukturen in der Ebene

For auditory and visual perception, virtual reality systems offer a high-resolution simulation of reality at low cost. To bring digitized objects even closer to reality, programmable structures are presented in this work, which should enable not only visual but also tactile perception. The foundation of the programmable structure is a cellular robot whose cells can both deform...

Unraveling the genetic complexity underlying sorghum response to water availability

Understanding the adaptation mechanisms of sorghum to drought and the underlying genetic architecture may help to improve its production in a wide range of environments. By crossing a high yielding parent (HYP) and a drought tolerant parent (DTP), we obtained 140 recombinant inbred lines (RILs), which were genotyped with 120 DArT and SSR markers covering 14 linkage groups (LGs...

Externalizing and internalizing problems: contributions of attachment and parental practices

The relation between attachment and parental practices with externalizing (aggression and delinquency) and internalizing (social withdrawal and anxiety/depression) behavioral problems were investigated in this study. Participants were 289 children (from 9 to 12 years old) and 205 caregivers who answered distinct questionnaires: the formers on attachment and the later on parental...

It constitutes an occupational disease that has a significant impact on the social and professional life of workers and their families. This paper focuses on analyzing the impact of noise in the power stations of the city of Ouagadougou. Participants and Methods: A prospective study was...

A community pharmacist medicines optimisation service for patients with advanced cancer pain: a proof of concept study

Background Patients with advanced cancer commonly experience pain and it is least controlled in community settings. Community pharmacists in the UK already offer medicines optimisation consultations although not for this patient group. Objective To determine whether medicines consultations for patients with advanced cancer pain are feasible and acceptable. Setting Community...

Re-writing the domestic role: transnational migrants’ households between informal and formal social protection in Ecuador and in Spain

Ecuadorian migration to Spain can be described as an emblematic case of feminization of international migration. As the scholarship showed, this migration flow has been shaped by transnational female social networks in which different types of capital circulate and which are re-produced across generations, providing social protection for people involved in them, both migrants and...

Synthesis and anticancer effects of α-lipoic ester of alloxanthoxyletin

Upon analyzing the structure-activity relationship, it was found that coumarin-based derivatives exerted cytotoxic and antitumor activity. In the present study a new ester of α-lipoic acid and derivative of alloxanthoxyletin (LAA) was synthesized and evaluated for its anticancer activity. The structure of this new compound was confirmed by 1H NMR, 13C NMR, and HRMS spectroscopic...

Spontaneous cavernosal abscess: a case report and review of literature

A cavernosal abscess is a rare condition. It can be idiopathic or with an underlying cause such as intracavernosal injection therapy, foreign bodies, perineal abscesses extension, priapism or trauma. The most common presenting symptoms were penile pain and swelling. Standard treatment consists of drainage via an incision, followed by broad-spectrum antibiotics where some authors...

Expression of socially sensitive genes: The multi-ethnic study of atherosclerosis

Background Gene expression may be an important biological mediator in associations between social factors and health. However, previous studies were limited by small sample sizes and use of differing cell types with heterogeneous expression patterns. We use a large population-based cohort with gene expression measured solely in monocytes to investigate associations between seven...

A reflected moving boundary problem driven by space–time white noise

We study a system of two reflected SPDEs which share a moving boundary. The equations describe competition at an interface and are motivated by the modelling of the limit order book in financial markets. The derivative of the moving boundary is given by a function of the two SPDEs in their relative frames. We prove existence and uniqueness for the equations until blow-up, and...

A long-term field experiment demonstrates the influence of tillage on the bacterial potential to produce soil structure-stabilizing agents such as exopolysaccharides and lipopolysaccharides

BackgroundStable soil aggregates are essential for optimal crop growth and preventing soil erosion. However, tillage is often used in agriculture to loosen the soil, which disrupts the integrity of these aggregates. Soil aggregation can be enhanced by bacteria through their ability to produce exopolysaccharides and lipopolysaccharides. These compounds stabilize soil aggregates by...

A taxonomy of shape-changing behavior for 4D printed parts using shape-memory polymers

4D printing (4DP) combines the use of additive manufacturing (AM) to produce freeform components with stimuli-responsive materials, so that the printed parts can transform over a calculated duration of time. This paper provides a collective review of the transformational behavior of 4D printed parts that can be achieved using shape-memory polymers (SMPs). Using the process of 4DP...

Total brachial artery reactivity and first time incident coronary heart disease events in a longitudinal cohort study: The multi-ethnic study of atherosclerosis

Background Brachial artery reactivity (BAR) is usually determined as the maximum brachial artery diameter (BAD) following release of an occluding pressure cuff compared to a BAD before cuff inflation. BAD early after cuff deflation can also serve as baseline for estimating total brachial artery reactivity (TBAR). We investigate whether TBAR is associated with first time coronary...

Parental manipulation of offspring size in social groups: a test using paper wasps

Maternal effects should be especially likely when mothers actively provision offspring with resources that influence offspring phenotype. In cooperatively breeding and eusocial taxa, there is potential for parents to strategically manipulate offspring phenotype in their own interests. Social insect queens are nearly always larger than their worker offspring, and queens could...
