Optimize training, enhance recovery, and improve performance with Performance Nutrition: Applying the Science of Nutrient Timing. Based on the most current research in nutrient timing, Performance Nutrition blends theory with applied content and real-life examples to help nutritionists, athletes, and coaches design nutrition plans based on each athlete’s individual needs and the specific demands of the sport.
While other texts may provide a brief discussion of nutrient timing as a tool for improving sport performance, Performance Nutrition: Applying the Science of Nutrient Timing focuses solely on this newly developing facet of sport nutrition. Distinguished authors Krista Austin (a physiologist and nutritionist) and Bob Seebohar (a sport dietitian and USA Triathlon elite coach) share their extensive practical experience with athletes at all levels from recreational through professional. They provide specific nutrient timing recommendations for a wide range of sport types, including endurance, strength and power, combative (weight classified), and team sports.
In particular, you will learn information on using nutrient timing theory to counteract altitude, heat and humidity, cold exposure, and air pollution. A chapter devoted to competition-day guidelines will help you keep your athletes hydrated, energized, and ready to perform. Plus, nutritional timelines, highlighted in special callout boxes and placed at the edge of the page for quick reference, offer visual plans of what athletes should eat in the hours leading up to and during competition. Practical and user friendly, this text also includes “In Practice” application exercises, mini-case studies, and four extended case studies to assist in translating the information to your own practice.
Incorporating nutrient ingestion timing into your athlete’s training program can promote enhanced recovery, create positive training adaptations, improve body composition, support immunity, and ultimately enhance performance. With Performance Nutrition: Applying the Science of Nutrient Timing, you will gain the foundational knowledge and practical techniques to develop individualized nutrition programs to improve training, performance, and recovery.
The influence of typhoons on atmospheric composition deduced from IAGOS measurements over Taipei
Authors: Roux Frank , Clark Hannah , Wang Kuo-Ying , Rohs Susanne , Sauvage Bastien , Nédélec Philippe 
Published: April 2020

Abstract. The research infrastructure IAGOS (In-Service Aircraft
for a Global Observing System) equips commercial aircraft with instruments
to monitor the composition of the atmosphere during flights around the
world. In this article, we use data from two China Airlines aircraft based
in Taipei (Taiwan) which provided daily measurements of ozone, carbon
monoxide and water vapour throughout the summer of 2016. We present time
series, from the surface to the upper troposphere, of ozone, carbon monoxide
and relative humidity near Taipei, focusing on periods influenced by the
passage of typhoons. We examine landing and take-off profiles in the
vicinity of tropical cyclones using ERA-5 reanalyses to elucidate the
origin of the anomalies in the vertical distribution of these chemical
species. Results indicate a high ozone content in the upper- to middle-troposphere
track of the storms. The high ozone mixing ratios are generally
correlated with potential vorticity and anti-correlated with relative
humidity, suggesting stratospheric origin. These results suggest that
tropical cyclones participate in transporting air from the stratosphere to
troposphere and that such transport could be a regular feature of typhoons.
After the typhoons passed Taiwan, the tropospheric column was filled with
substantially lower ozone mixing ratios due to the rapid uplift of marine
boundary layer air. At the same time, the relative humidity increased, and
carbon monoxide mixing ratios fell. Locally, therefore, the passage of
typhoons has a positive effect on air quality at the surface, cleansing the
atmosphere and reducing the mixing ratios of pollutants such as CO and O3.

Published: April 2020

Abstract. Characterizing methane sources in the Arctic remains challenging due to the remoteness, heterogeneity and variety of such emissions. In
situ campaigns provide valuable datasets to reduce these uncertainties. Here we analyse data from the summer 2014 SWERUS-C3 campaign in the
eastern Arctic Ocean, off the shore of Siberia and Alaska. Total concentrations of methane, as well as relative concentrations of 12CH4 and
13CH4, were measured continuously during this campaign for 35 d in July and August. Using a chemistry-transport model, we link
observed concentrations and isotopic ratios to regional emissions and hemispheric transport structures. A simple inversion system helped constrain
source signatures from wetlands in Siberia and Alaska, and oceanic sources, as well as the isotopic composition of lower-stratosphere air masses.
The variation in the signature of lower-stratosphere air masses, due to strongly fractionating chemical reactions in the stratosphere, was suggested
to explain a large share of the observed variability in isotopic ratios. These results point towards necessary efforts to better simulate large-scale
transport and chemistry patterns to make relevant use of isotopic data in remote areas. It is also found that constant and homogeneous source
signatures for each type of emission in a given region (mostly wetlands and oil and gas industry in our case at high latitudes) are not compatible
with the strong synoptic isotopic signal observed in the Arctic. A regional gradient in source signatures is highlighted between Siberian and
Alaskan wetlands, the latter having lighter signatures (more depleted in 13C). Finally, our results suggest that marine emissions of
methane from Arctic continental-shelf sources are dominated by thermogenic-origin methane, with a secondary biogenic source as well.
Microstructure and composition of marine aggregates as co-determinants for vertical particulate organic carbon transfer in the global ocean

Published: April 2020

Abstract. Marine aggregates are the vector for biogenically bound carbon and nutrients from the euphotic zone to the interior of the oceans. To improve the representation of this biological carbon pump in the global biogeochemical HAMburg Ocean Carbon Cycle (HAMOCC) model, we implemented a novel Microstructure, Multiscale, Mechanistic, Marine Aggregates in the Global Ocean (M4AGO) sinking scheme. M4AGO explicitly represents the size, microstructure, heterogeneous composition, density and porosity of aggregates and ties ballasting mineral and particulate organic carbon (POC) fluxes together. Additionally, we incorporated temperature-dependent remineralization of POC. We compare M4AGO with the standard HAMOCC version, where POC fluxes follow a Martin curve approach with (i) linearly increasing sinking velocity with depth and (ii) temperature-independent remineralization. Minerals descend separately with a constant speed. In contrast to the standard HAMOCC, M4AGO reproduces the latitudinal pattern of POC transfer efficiency, as recently constrained by Weber et al. (2016). High latitudes show transfer efficiencies of ≈0.25±0.04, and the subtropical gyres show lower values of about 0.10±0.03. In addition to temperature as a driving factor for remineralization, diatom frustule size co-determines POC fluxes in silicifier-dominated ocean regions, while calcium carbonate enhances the aggregate excess density and thus sinking velocity in subtropical gyres. Prescribing rising carbon dioxide (CO2) concentrations in stand-alone runs (without climate feedback), M4AGO alters the regional ocean atmosphere CO2 fluxes compared to the standard model. M4AGO exhibits higher CO2 uptake in the Southern Ocean compared to the standard run, while in subtropical gyres, less CO2 is taken up. Overall, the global oceanic CO2 uptake remains the same. With the explicit representation of measurable aggregate properties, M4AGO can serve as a test bed for evaluating the impact of aggregate-associated processes on global biogeochemical cycles and, in particular, on the biological carbon pump.
Waveguidability of idealized midlatitude jets and the limitations of ray tracing theory
Authors: Wirth Volkmar 
Published: April 2020

Abstract. Ray paths of stationary Rossby waves emanating from a local midlatitude source are usually refracted equatorward. However, this general tendency for equatorward propagation is mitigated by the presence of a midlatitude jet that acts as a zonal waveguide. This opens up the possibility of circum-global teleconnections and quasi-resonance, which suggests that the ability to guide a wave in the zonal direction is an important jet property. This paper investigates waveguidability of idealized midlatitude jets in a barotropic model on the sphere. A forced-dissipative model configuration with a local source for Rossby waves is used in order to quantify waveguidability by diagnosing the latitudinal distribution of waviness in a longitudinal sector far downstream of the forcing. Systematic sensitivity experiments show that waveguidability increases smoothly with increasing jet amplitude and with decreasing jet width. This result is contrasted with the predictions from two idealized theoretical concepts based on (1) ray tracing as derived from Wentzel–Kramers–Brillouin (WKB) theory and (2) a sharp jet with a zonally oriented front of potential vorticity. The existence of two so-called turning latitudes, which is the key diagnostic for a zonal waveguide according to ray tracing theory, turns out to be a poor predictor for the dependence of waveguidability on jet amplitude and jet width obtained in the numerical simulations. By contrast, the meridional gradient of potential vorticity correlates fairly well with the diagnosed waveguidability. The poor predictions from ray tracing are not surprising, because the underlying WKB assumptions are not satisfied in the current context. The failure of WKB is traced back to the properties of the underlying equations, and a heuristic argument is presented to elucidate the potential of the potential vorticity (PV) gradient to act as a proxy for waveguidability.

Published: April 2020

The aim of this study was to determine the occurrence of pathogens in selected group of ewes and the relationship between somatic cell count (SCC) and the presence of pathogens. The experiment was carried out on a dairy farm, where predominantly breed was a Tsigai. Sampling was carried out in monthly intervals as part of the milk recording test day from February to July 2019. A total of 303 ewes were included in the survey, during the milk recording test day. The ewes with SCC ≥1000 × 103 cells.mL-1 were selected for further sampling at half udder level. Based on SCC the ewes were divided into five groups: <200 ×103; ≥200 <400 × 103; ≥400 <600 × 103; ≥600 <1000 × 103; ≥1000 × 103 cells.mL-1. The first group of SCC contained 33.9% of milk samples, the second 14.1% of samples, the third 5.7% of samples, the fourth 6.2% and the fifth 40.1% of samples. The most common pathogens were coagulase negative staphylococci (CNS). The most frequent CNS was Staphylococcus (S.) simulans (24.4%). S. aureus was identified in 5.3% of bacteriological positive samples. Almost 70% of ewes with bacteriological positive samples were repeated identified the presence of pathogens during tested period. SCC ≥500 × 103 cells.mL-1 were detected in 92.5% bacteriological positive milk samples. The presence of pathogens increased SCC in milk (p <0.001) as compared to samples free of pathogens. In conclusion, the SCC ≥500 × 103 cells.mL-1 could be important for detection of subclinical mastitis at half udder level in dairy ewes.

Published: April 2020

This study was carried out to examine the effect of institutional factors in marketing of agricultural products by cooperative farmers in Anambra State of Nigeria. Four specific objective The study focused on four specific objectives which were to; examine the socio-economic characteristicsof the cooperative farmers and its effect on market participation; determine the quantum and value of agricultural produce that had been marketed; identify the extent to which agricultural market participation of the framer is influenced by institutional factors such as market information, organizational support, use of grades and standards, and legal environment; and make recommendations based on the findings. Three hypotheses were also tested. Descriptive survey design was used for the study where seven hundred and ten (710) was used as sample size. Findings revealed that market disposition of the member was not related to duration of membership which implied that cooperative experience do not have substantial influence on marketing decisions. Farmers affirmed institutional factors such as influence of tradition and cultural practices; legal environment relating to laws governing sale of agricultural products, land tenure system, organizational supports from the government, availability of market information; and use of grades and standards in agricultural marketing significantly influenced their marketing decisions. It was further revealed that institutional factors have no influence on market participation of the cooperative farmers. In conclusion institutional factors have significant influence on marketing decisions while socio-economic characteristics of members have no significant influence on market participation by the cooperative farmers. Based on the findings, it was further recommended that government should always create an enabling environment to encourage farmers to continue to participate in agricultural markets. They can do this by re-examining laws and regulation that appear to impact negatively on farm production and agricultural marketing. This may include abrogation of the land tenure Act that has over the years, hindered access to agricultural farmlands by individual farmers among others.

Critical Public Administraton: towards a reflexive perspective on public policy and governance
Over the past four decades of its existence, Dutch public administration has developed into a science which mainly produces knowledge that either caters to a very specific scientific niche or aims to optimize policy processes in an instrumental fashion. This type of knowledge is not well equipped to provide answers or improve understanding of the challenges of our time. We argue that public administration needs to shift its focus more towards producing reflexive knowledge in the form of what we would call critical public administration. Based on the contributions in this special issue, this article outlines what the contribution of such a critical public administration could be. The article shows that, even though it is theory driven, critical public administration is close to policy practice and can fuel a productive public debate by imagining alternative futures.

20 years of Accountability Day: Insight for parliamentary committees. How content analysis provides insight into Performance Data use by Members of Parliament
The 20th Accountability Day of the Netherlands House of Representatives is a fitting occasion to investigate whether Dutch Members of Parliament use performance information (PI). Performance information used by managers and politicians is a basic assumption for managing and guiding Performance-based Budgeting. Ironically, based on a literature review on performance use, we know that politicians and especially parliamentarians do not use performance information for decision making or scrutiny. This is specifically so when PI reports are long. Using the framework of accountability of Bovens (2007) and using content analysis of the questions, motions and debates of the Standing Committees on the annual reports, this article shows that MPs use performance information in all phases (informing, debating, sanctions). Contradicting earlier research on parliamentarians, we found that they use annual reports and reports of the Court of Audit as their main sources in the debates. This article shows that the use of PI in parliament is steadily rising. The growing importance of performance information for accountability is further illustrated by the strengthening of the accountability forum.
