Coating strategies for atomic layer deposition
Authors: Hu Liang , Qi Weihong , Li Yejun 
Published: August 2017

AbstractAtomic layer deposition (ALD) is a vapor phase technique capable of producing a variety of materials. It consists of the alternation of separate self-limiting surface reactions, which enables accurate control of film thickness at the Angstrom level. ALD becomes a powerful tool for a lot of industrial and research applications. Coating strategies are the key for ALD; however, there are few systematic reviews concerning coating strategies for ALD. This review provides a detailed summary of state-of-the-art coating strategies in ALD, emphasizing the recent progress in the fabrication of novel nanostructures. The progress in coating strategies is reviewed in three parts: template-assisted preparation of low-dimensional nanomaterials and complex nanostructures; surface treatments, including the surface activation and the surface blocking ways; enhanced reactor, such as plasma and fluid bed reactor, and improved growth method such as the ABC-type model. In addition, we also discussed the challenges facing the coating method for ALD.

Abstract
Halloysite nanotubes (HNTs) were modified by γ-methacryloxypropyltrimethoxysilane (γ-MPS) as it interacts with the aluminol and silanol groups of HNTs present at the edges and surfaces of HNTs. The polymer composites were prepared by means of the solution casting method with ethylene-vinyl acetate (EVA) copolymer having 45% vinyl acetate (VA) content with different weight percent of modified HNTs (m-HNTs). The modification of the HNTs by γ-MPS increases the interfacial and inter-tubular interactions and the degree of dispersion of the HNTs within the EVA matrix which manifest from increase in crosslinking density. The mechanical properties such as tensile strength, tensile modulus and tear strength of nanocomposites were found to increase because of m-HNT. The glass transition temperature (Tg) and the crystalline percentage decreases for EVA/m-HNT nanocomposites were due to the strong interaction between EVA matrix and filler. Also, the EVA/m-HNT nanocomposites exhibited better thermal stability due to the strong inter-tubular interaction.
Negative concord in Quebec French
Authors: Labelle Marie 
Published: August 2017

AbstractIt is argued that there are two types of asymmetric negative concord languages: in languages like Spanish and Italian, negative concord results from a purely formal agreement relation between the negation and a negative concord item. In Quebec French, in addition to this purely formal licensing, there is a negative dependency relation between both items, which form two segments of a discontinuous negative quantifier. This accounts for the following differences. While Spanish, Italian and Quebec French reject negative concord between a subject negative expression and the negation, in Quebec French, negative concord with the negation becomes possible when the clause contains a postverbal negative expression in addition to a preverbal one. Moreover, in Quebec French, but not in Spanish or Italian, negative concord is blocked across a quantifier meaning

Abstract
de la Motte, SJ, Gribbin, TC, Lisman, P, Murphy, K, and Deuster, PA. A systematic review of the association between physical fitness and musculoskeletal injury risk: part 2—muscular endurance and muscular strength. J Strength Cond Res 31(11): 3218–3234, 2017—This is a systematic review and evaluation of the current evidence on the association between both muscular endurance (ME) and muscular strength (MS) and musculoskeletal injury (MSK-I) risk in military and civilian populations. MEDLINE, EBSCO, EMBASE, and the Defense Technical Information Center were searched for original studies published from 1970 through 2015 which examined associations between physical fitness (ME and MS) and MSK-I in military or civilian populations. Methodological quality and strength of the evidence were determined following criteria adapted from previously published systematic reviews. Forty-five of 4,229 citations met our inclusion criteria. Although results for some tests did vary by sex, taken together, our primary findings indicate there is (a) a strong evidence that poor performance in a push-up test is associated with MSK-I risk; (b) moderate evidence that poor performance in sit-up test is associated with MSK-I risk; (c) moderate evidence that isokinetic ankle and knee flexion strength, and isometric strength assessments at the back, elbow, or knee are associated with MSK-I risk; and (d) limited evidence that poor performance in a pull-up test and isotonic assessments of muscular strength are associated with MSK-I. Several measures of ME/MS are moderately or strongly associated with risk of MSK-I, but additional research is needed to identify and recommend specific assessments of ME/MS that predict MSK-I in both men and women. Future studies should also consider measures of ME and MS as a function of upper body, lower body, and core strength, and their potential association with specific, rather than general, MSK-I.

Abstract
Weakley, JJS, Till, K, Read, DB, Phibbs, PJ, Roe, G, Darrall-Jones, J, and Jones, BL. The effects of superset configuration on kinetic, kinematic, and perceived exertion in the barbell bench press. J Strength Cond Res 34(1): 65–72, 2020—Training that is efficient and effective is of great importance to an athlete. One method of improving efficiency is by incorporating supersets into resistance training routines. However, the structuring of supersets is still unexplored. Therefore, the purpose of this study was to assess the effects of agonist-antagonist (A-A), alternate peripheral (A-P), and similar biomechanical (SB) superset configurations on rate of perceived exertion (RPE), kinetic and kinematic changes during the bench press. Ten subjects performed resistance training protocols in a randomized-crossover design, with magnitude-based inferences assessing changes/differences within and between protocols. Changes in rate of perceived exertion were very likely and almost certainly greater in the A-P and SB protocols when compared with the A-A, whereas all superset protocols had very likely to almost certain reductions in mean velocity and power from baseline. Reductions in mean velocity and power were almost certainly greater in the SB protocol, with differences between the A-A and A-P protocols being unclear. Decreases in peak force were likely and almost certain in the A-A and SB protocols respectively, with changes in A-P being unclear. Differences between these protocols showed likely greater decreases in SB peak forces when compared to A-A, with all other superset comparisons being unclear. This study demonstrates the importance of exercise selection when incorporating supersets into a training routine. It is suggested that the practitioner uses A-A supersets when aiming to improve training efficiency and minimize reductions in kinetic and kinematic output of the agonist musculature while completing the barbell bench press.

Abstract
Bunn, JA, Ryan, GA, Button, GR, and, and Zhang, S. Evaluation of strength and conditioning measures with game success in Division I collegiate volleyball: A retrospective study. J Strength Cond Res 34(1): 183–191, 2020—The purpose of this study was to retrospectively assess relationships between strength and conditioning (SC) measures and game performance in Division I volleyball. Five years of SC and game data were collected from 1 women's Division I collegiate team, n = 76. Strength and conditioning measures included T-drill, 18.3 m sprint, back squat, hang clean, vertical jump, and broad jump. All game and SC stats were normalized to Z-scores. Analyses included assessing SC differences by position and multiple stepwise regression to assess relationships between game and SC stats. There was a significant difference by position for broad jump (p = 0.002), 18.3 m sprint (p = 0.036), vertical (p ≤ 0.001), and total strength (p = 0.019). Overall, game performance and SC measures were significantly correlated (r = 0.439, p ≤ 0.001). Multiple regression analyses indicated significant relationships (p ≤ 0.05) between SC measures and game success by position as follows: defensive specialist stats with squat and total strength; setters game stats with hang cleans, T-drill, and broad jump; pin hitter game stats with vertical, squat, and total strength; middle blockers game stats with broad jump. These data indicate that SC measures correlate well with game performance and are specific by position. These data could help SC coaches create a more precise training approach to focus on improving specific measures by position, which could then translate to improved game performance. These data could also help coaches with talent identification to determine playing time and rotations to maximize player ability and achieve success.
Multiple limit cycles in a Leslie–Gower-type predator–prey model considering weak Allee effect on prey
Authors: González-Olivares Eduardo , Rojas-Palma Alejandro , González-Yañez Betsabé 
Published: August 2017

In this work, a modified Leslie–Gower-type predator–prey model is analyzed, considering now that the prey population is affected by a weak Allee effect, complementing results obtained in previous papers in which the consequences of strong Allee effect for the same model were established.In order to simplify the calculations, a diffeomorphism is constructed to obtain a topological equivalent system for which we establish the boundedness of solutions, the nature of equilibrium points, the existence of a separatrix curve dividing the behavior of trajectories. Also, the existence of two concentric limit cycles surrounding a unique positive equilibrium point (generalized Hopf or Bautin bifurcation) is shown.Although the equilibrium point associated to the weak Allee effect lies in the second quadrant, the model has a rich dynamics due to this phenomenon, such as it happens when a strong Allee effect is considered in prey population.The model here analyzed has some similar behaviors with the model considering strong Allee effect, having both two limit cycles; nevertheless, they differ in the amount of positive equilibrium points and the existence in our model of a non-infinitesimal limit cycle, which exists when the positive equilibrium is a repeller node. The main results obtained are reinforced by means of some numerical simulations.

The aim of this study was to estimate the intake of dry matter forage (CMSf) by grazing holstein cows. The research was conducted in northern Antioquia highlands; a silvopastoral system with Tithonia diversifolia and Cenchrsus clandestinum (SSP) and a monoculture C. clandestinum were used. Were estimated the CMSf by different methodologies and kikuyu:wild sunflower consumption relation, also the interchangeability of two methodologies was determined. There were two conducted trials, in the first trail SSP was used without browsing of wild sun ower and monoculture; in the second trial the same system was applied, with the difference that for the SSP animals browsed the shrubby by themselves. Twelve random infant holstein cows were used in the two systems. CMSf was estimated by indicators (I), agronomic (A) and grazing behavior (C) methods, method I was the reference. In trial I more CMSf was observed in the SSP, with an average of 14.7 kg/day (p<0.05); trial II showed no difference in the CMSf, with an average of 13.3 kg/day (p>0.005). The kikuyu:wild sunflower consumption relation was 95:5. The correlation coefficient of concordance between the methods I and C near to 0 shown that they are not interchangeable. The results suggest that the SSP evaluated supplied sufficient forage to ensure optimal CMSf.

The objective of this work was to evaluate the dynamic of corn and bean production in Mexico. Retrospective analysis was conducted in order to identify critic points, changes and adjustments given in the sector, as a result of Mexican government policies. Data was obtained from SAGARPA, Bank of Mexico, Secretary of Economy and Food and Agriculture Organization. Indicators were evaluated, as annual average growth rate (TCMA) and growing indicators, trends and real prices were evaluated. When doing the analysis, it was considered as a variable the country as a whole. The data of plantings, production, prices and imports of corn and beans in Mexico between 1980 and 2014 was analyzed. The plantings of corn and beans showed a decrease of 1.8 million and 193 thousand hectares respectively, the performance of corn increased on 1.47 t/ha and for beans, and 160 kg/ha for corn production and had a TCMA of 1.8% equivalent to 10.1 million tons, and beans had a TCMA of 0.89% with an increase of 338 783 t. Corn and beans, at constant prices, had a decrease of 64.6% and 59.0%, the decreased was of 441.9 and 976.3 dollars per ton respectively. The imports of corn had a TCMA of 2.84% ending 2012 with 9.5 million tons, the imports of beans don’t show any trend. The critic point of imports began with the North American Free Trade Agreement, where Mexico changed from a close economy to an open one, in which the government stimulates more imports, than national production.

Sobre a possível origem da diferença fonética entre a fala masculina e a feminina em Karajá
Authors: Rodrigues Aryon Dall'Igna 
Published: August 2017

Este trabalho discute a hipótese, aventada em trabalho anterior do mesmo autor (Rodrigues 1999), de que a origem da diferenciação entre fala masculina e fala feminina, no Karajá, deve-se a uma interferência de falantes da língua Xavante (família Jê). O exame da documentação mais antiga sobre as duas línguas em questão, nos registros da primeira metade do século XIX, trazem algum problema para a hipótese em questão, mas neste texto propõe-se uma explicação que mantém a hipótese da interferência, relacionando Karajá com o Xavante atual.
Three-Dimensional Modeling of PDC Bits

Published: August 2017

ABSTRACT
PDC bit modeling has historically incorporated the assumption that cutter forces are constant for a full revolution of the bit. This assumption places considerable limitations on the model's ability to simulate drilling in nonhomogeneous rock and in cases where the bit whirls. Recent studies have shown that cutter damage due to impact loading is a primary cause of PDC bit failure. These impacts may be caused by both bit whirl and drilling through nonhomogeneous rock. The three dimensional model presented in this paper provides the capability to evaluate cutter loading for both of these conditions. It shows that the cutter loads for common drilling situations may be as much as ten times greater than those calculated with previously available two dimensional models.

Core Ideas
High levels of ash content provide no nutritional benefit to livestock.
A hay merger or sidebar rake resulted in less ash content compared to a wheel rake.
Rake type rarely resulted in differences in forage nutritive values.
High levels of ash content are problematic in hay since ash provides no nutritional benefit to livestock. Hay raking may impact ash content, but the effect of different hay rake types on ash content is unknown. The objectives were to determine the effect of rake type on ash content and forage nutritive values of alfalfa (Medicago sativa L.) hay. Replicated trials were conducted on two cuttings of alfalfa in Minnesota, Pennsylvania, and Wisconsin. During raking, two swath rows were combined using one of the following rake types: wheel, sidebar, rotary, or merger. Samples were collected during the four phases of hay harvest: standing forage, post‐cut, post‐raked, and post‐baled or chopped and analyzed for ash content and forage nutritive values. Ash content was different in five of the six sites‐cuttings post‐raking (P ≤ 0.05). The hay merger and sidebar rake resulted in the least amount of ash (90–136 g kg−1) while the wheel rake (100–153 g kg−1) resulted in the greatest amount of ash. Differences in forage nutritive values were rarely observed due to rake type and ranged from 200–241 g kg−1 crude protein (CP), 374–480 g kg−1 NDF, and 393 to 532 g kg−1 neutral detergent fiber digestibility (NDFd) post‐raking. First cutting alfalfa differed in relative forage quality (RFQ) post‐raking where the hay merger and sidebar rake tended to result in greater RFQ values (121–165) compared with the wheel rake (114–160; P ≤ 0.05). Using a hay merger or sidebar rake to combine swaths resulted in less ash content compared with a wheel rake; however, rake type rarely resulted in differences in forage nutritive values.

Core Ideas
Planting date and maturity group decisions can greatly affect yield and composition.
Temperature had a significant effect on seed yield and composition.
Planting date × maturity group should be chosen based on the product's end use.
Soybean [Glycine max (L.) Merr.] production has greatly increased in the upper U.S. Midwest over the last decade, but little information exists regarding the interactive effects of environment and spring management decisions on soybean seed yield and composition. Our objective was to assess the effect of four planting dates (PDs), four cultivar maturity groups (MGs), and ambient temperature between R5 to R8 (T5–T8) on soybean seed yield and composition. Field studies were established between 2014 and 2016 at three locations in Wisconsin and one in Minnesota. Across environmental conditions and management decisions, greater seed yield was positively correlated with protein and oil contents but negatively correlated with linoleic, linolenic, and sucrose contents. Multivariate data analysis showed positive synergies between early planting (late April–early May) and MG 2 for yield, oil, and oleic acid across the examined region. A MG 2 was the highest yielding and a ∼1200 kg ha−1 yield difference was observed between early and late PDs. These results underline the complexity of the soybean yield‐composition relationships. Additionally, the large variability in the responses of constituents to management decisions and temperature variations highlights the importance of a producer knowing the product's end use (e.g., high yield vs. high protein) and accordingly modifying the growing environment by selecting an appropriate PD and MG for the respective region. To provide more accurate recommendations to a broader range of producers, multi‐environment studies are imperative to capture large environmental variability in important soybean production areas across the United States.
Meta‐Analysis of Phosphorus Loss from No‐Till Soils
Authors: Daryanto Stefani , Wang Lixin , Jacinthe Pierre André 
Published: August 2017

Agriculture is a significant contributor to phosphorus (P) enrichment in aquatic ecosystems. No‐till (NT) farming has been proposed as an alternative approach to conventional tillage (CT) in reducing soil P export, but published data have shown contrasting impacts, likely due to the interacting effects of different physical (climate region, rainfall variability, transport pathway, slope gradient) and management variables (NT duration, crop species). We conducted a meta‐analysis to understand the extent to which each of these variables controls the concentration and load of different P fractions (dissolved P, particulate P) in agricultural runoff and leaching. In comparison with CT, particulate P loss was significantly lower with NT adoption (45 and 55% reduction in concentration and load, respectively), but an increase in dissolved P loss was observed. The extent of the reduction or increase, however, varied with different physical and management variables. In comparison with CT, for example, NT was not effective in reducing particulate P concentration during wet years and particulate P load on steep slopes (4–9%). Total P concentration was also similar with CT at sites under prolonged NT duration (∼10 yr) and at NT fields planted with soybean [Glycine max (L.) Merr.]. Our results underscore the need to consider the covarying physical and management factors when assessing the potential of NT farming in controlling P loss in the environment. The limited impact of NT on dissolved P loss remains a serious impediment toward harnessing the water quality benefits of this management practice.Core Ideas
No‐till was effective in reducing particulate P loss but increased dissolved P loss.
NT covaried with several physical and management variables in affecting P loss.
NT must be combined with other land management strategies to reduce dissolved P loss.
