The ubiquitous electrochemistry is expected to play a major role for reliable energy, and for production of sustainable fuels and chemicals. For organics-based electrocatalysis in an alkaline medium, the fundamental understandings at solid-liquid interfaces involve relatively complex mechanisms and performance descriptors (from the electrolyte and reaction intermediates), which undermine the roads towards advance and breakthroughs. Here, we review and diagnose recently designed strategies for the electrochemical conversion of organics into electricity or high added- value chemicals, and likely both...

A total of 272 students at a German university were asked to write down the story of an ingratiation attempt they had made and one they had received. They were then asked to reflect on each episode via a questionnaire. All but one participant reported that they had performed at least one of the four tactics postulated in Jones's ingratiation theory: compliments, favor-doing, opinion conformity, and positive self-presentation. In the case of received ingratiation, we found higher success ratings for nondependent (vs...

Today Chronic Myeloid Leukemia (CML) relapse's final assessment and monitoring in the whole world is implemented by BCR-ABL gene quantitative detection - during the polymerase chain reaction (by PSR means). Implementation of this monitoring materially and technically is not often available and remission during years is being assessed using monthly clinical-laboratory data. Proceeding from this, the goal of our work was to find the clinical-laboratory features, indicating the expected relapse and require the urgent molecular research carry out...

Development of resistance in the Plasmodium falciparum to Artemisinin, the most effective anti-malarial compound, threatens malaria elimination tactics. To gain more efficacious Artemisinin derivatives, QSAR modeling and docking was performed. In the present study, 2D-QSAR model and molecular docking were used to evaluate the Artemisinin compounds and to reveal their binding modes and structural basis of inhibitory activity. Moreover, ADMET-related descriptors have been calculated to predict the pharmacokinetic properties of the effective compounds...

Males often fight with rival males for access to females. However, some males display nonfighting tactics such as sneaking, satellite behavior, or female mimicking. When these mating tactics comprise a conditional strategy, they are often thought to be explained by resource holding potential (RHP), that is, nonfighting tactics are displayed by less competitive males who are more likely to lose a fight. The alternative mating tactics, however, can also be explained by life-history theory, which predicts that young males avoid fighting, regardless of their RHP, if it pays off to wait for future reproduction...

Diversity in life history tactics contributes to the persistence of a population because it helps to protect against stochastic environments by varying individuals in space and time. However, some life history tactics may not be accounted for when assessing the demographic viability of a population. One important factor in demographic viability assessments is cohort replacement rate (CRR), which is defined as the number of future adults produced by an adult. We assessed if precocial resident males (<age-3) and adfluvial Chinook salmon (Oncorhynchus tshawytscha), adults that reside in freshwater their entire lives, contributed offspring to a reintroduced population from 2008 to 2013...

Some animals hide food to consume later; however, these caches are susceptible to theft by conspecifics and heterospecifics. Caching animals can use protective strategies to minimize sensory cues available to potential pilferers, such as caching in shaded areas and in quiet substrate. Background matching (where object patterning matches the visual background) is commonly seen in prey animals to reduce conspicuousness, and caching animals may also use this tactic to hide caches, for example, by hiding coloured food in a similar coloured substrate...

BACKGROUND: Some cancer survivors say that while coping with their illness they have had what they identify as a highly beneficial, personal, life-transforming change (LTC; a self-subscribed condition among participants in this study, not a researcher-defined construct). Previously we found that the content of LTC was highly individual; but certain features of the LTC process were quite uniform. For example, LTC was driven by a very rational desire to remain genuinely functional as a person in the midst of highly stressful circumstances...

Min Chen, Jianwei Sun
The use of additives for organic synthesis has become a common tactic to improve organic reaction outcomes. In this report, using an organocatalytic process for the synthesis of chiral diarylmethyl alkynes as a platform, we describe how an additive is involved in the improvement of the process. The evolution of an excellent synthetic protocol has been achieved via three stages, from (1) initially no catalyst turnover to (2) good conversion and enantioselectivity with a superior additive, and eventually (3) even better efficiency and selectivity without using additive...

Widely substituted all-carbon quaternary and tertiary α-homoallyl aldehydes are rapidly assembled through a unique synthetic operation from ketones consisting in: 1) C1-homologation; 2) epoxide-aldehyde Lewis acid mediated isomerization and, 3) electrophilic trapping. The synthetic equivalence between a vinyl oxirane and a β,γ-unsaturated aldehyde is the key concept for introducing such a previously undisclosed tactic. Mechanistic studies and labeled experiments suggest the intervention of an aldehyde enolate as the crucial intermediate...

Lígia H Apostólico, José E A R Marian
Sperm competition is a powerful postcopulatory selective force influencing male adaptations associated with increasing fertilization success, and it is usually related to the evolution of different strategies of ejaculate expenditure between individuals. Ejaculates may also be influenced by additional selective pressures associated with sperm competition, such as timing between insemination and fertilization, female reproductive tract morphology, and fertilization environment. Also, males that adopt alternative mating tactics may face distinct sperm competition pressures, which may lead to the evolution of intraspecific diversity in ejaculates...

The American military is embarking on the 'Third Offset'-a strategy designed to produce seismic shifts in the future of warfare. Central to the approach is the conjoining of humans, technology, and machines to deliver a decisive advantage on the battlefield. Because technology will spread rapidly and globally, tactical overmatch will occur when American operators possess a competitive edge in cognition. Investigation of cognitive enhancing therapeutics is not widely articulated as an adjunct to the Third Offset, yet failure to study promising agents could represent a strategic vulnerability...

BACKGROUND: The spatial distribution of insects is due to the interaction between individuals and the environment. Knowledge about the within-field pattern of spatial distribution of a pest is critical to planning control tactics, developing efficient sampling plans, and predicting the pests' damages. The leaf miner Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae) is the main pest in tomato crops in several regions of the world. Despite the importance of this pest, the pattern of spatial distribution of T...

Previous studies indicate positive home advantage in judo; however, the factors that influence home advantage have yet to be fully explored. This study investigated the potential differences in technical-tactical variables between home and visiting athletes. A total of 1411 video recorded matches were analyzed (123 home, 1288 away) from 36 international judo competitions contested in 2011-12. The matches were analyzed by the following criteria: combat phases (approach, gripping, attack, defense, groundwork and pause), penalties (by the athlete or the opponent) and the types of attacks (with or without a score)...

The analysis of positional data in association football allows the spatial distribution of players during matches to be described in order to improve the understanding of tactical-related constraints on the behavioural dynamics of players. The aim of this study was to identify how players' spatial restrictions affected the exploratory tactical behaviour and constrained the perceptual-motor workspace of players in possession of the ball, as well as inter-player passing interactions. Nineteen professional outfield male players were divided into two teams of 10 and 9 players, respectively...

There is an ever-growing need for clinically focused, culturally relevant research on which nurses can base their practice. However, there may not be a concurrent rise in efforts to strengthen infrastructure needed to promote research in developing and low-income countries. In such cases, nurse researchers must find innovative ways to address and overcome barriers to research. This article presents five exemplars of nurses conducting high-quality nursing research in resource-poor settings in southern and eastern Africa...
