Monitoring the epizoetic situation on mixed infectious diseases in bees in Northern Eastern region of Ukraine
Authors: Kisil D.O. , Fotina T.I.
Published: June 2018

In most countries of the world, infectious diseases of bees are an important problem for beekeeping, as they lead to a decrease and decrease in the number of bee colonies, a negative impact on the environment, a decrease in the yield of entomophilic crops and the overall productivity of the industry as a whole. According to data from statistical reporting and scientific publications, American and European flocks, ascospheros are registered in apiaries almost all over the world: in Western and Eastern Europe, North and Central America, Canada, Australia and New Zealand, Africa, in the CIS countries. The change in the epizootic situation in bee-keeping is associated with the widespread spread of the varioise invasion, which causes a steady increase in the incidence of bee infestation by infectious diseases, so the effect of this invasion on the intensity of the epizootic process requires constant monitoring research. Among the topical tasks of the veterinary support of the beekeeping industry in the improvement of the system of antiepizootic measures, the differential diagnosis of infectious diseases of the breeding pedigree in the mixed forms of their manifestation was very important. The difficulty in making the correct diagnosis in mixed forms of the course of infectious diseases leads to inadequate and untimely conduct of treatment and preventive measures, and as a consequence, to the weakening and death of bees. In this regard, the development of an epizootiological monitoring system aimed at recording and evaluating changes in the epizootic state of apiaries, the identification of sources and reservoirs of pathogens, the motive forces of the epizootic process and the forms of the disease, and the organization of a system of effective preventive, medical and veterinary-sanitary measures on the apiaries. In the period of economic transformations in the agrarian-industrial complex there was a lack of breeding of beekeeping farms and apiaries, a system of management of the industry and a form of ownership changed, all this created a qualitatively new environment of the bee colony and contributed to the evolution of the epizootic process in infectious diseases – the development of mixed infections. In connection with this, there was a need to improve the system of epidemiological surveillance in beekeepers and to introduce a more effective comprehensive system of measures for the prevention and control of infectious diseases of the breeding bee, in particular, American rot, varrosis and other contagious diseases of bees.

Published: June 2018

Successful functioning of an organization, especially agricultural one, implies the necessity for a properly organized system of employee health and safety. The system will function properly only when employees perceive organizational safety processes and procedures as a part of their behavior at work. The purpose of this study with reference to scientific literature and empirical research to determine the main factors that predict higher safety climate in organization. 961 employees from a large Lithuanian company of agricultural industry participated in the survey. The study was conducted using Sexton’s Safety Climate Questionnaire and two scales from Copenhagen Psychosocial Questionnaire. The analysis of data via Structural Equation Modeling confirmed the theoretical model of psychosocial safety climate antecedents. The findings of the study showed that employee trust in management had higher predictive value as compared to workplace commitment, and that the leader’s role in promoting safety in an organization is more important than employee attitudes or declared safety-related orders and procedures in the organization.
A cemetery of the Gáta–Wieselburg culture at Nagycenk (Western Hungary)
Authors: Gömöri János , Melis Eszter , Kiss Viktória
Published: June 2018

The 29 individuals found in 27 graves at Nagycenk were buried there in the time period between 2000–1700 BC, according to radiocarbon dates – i.e. at the beginning of the Middle Bronze Age in Hungary. The cemetery is of unique importance, both because of the richness of burial assemblages (altogether 30 bronze objects, 5 gold jewelries) and the scarcity of known Gáta–Wieselburg cemeteries. 15 percent of the ca. 180 burials in total, which relate to this culture in Hungary, are in this cemetery, and because of the few published burial sites, the cemetery at Nagycenk represents about one fourth of the materials published so far in the whole distribution area of the culture. Pottery style, typology and raw material of metal artefacts, as well as the radiocarbon dates (with the earliest among the published radiocarbon dates in context of this culture) support the dating of the cemetery section to the early phase of the Gáta–Wieselburg culture. The oval arrangement of burials around grave 55 and grave 1 suggest that each of these correspond to a household of high status men representing a few generations of the population living in the settlement excavated in the vicinity of Nagycenk.

Impact of MRSA on the military medical service and diagnostic point-of-care options for the field setting
Authors: Frickmann Hagen
Published: June 2018

Methicillin-resistant Staphylococcus aureus (MRSA) poses an infection risk for international military deployments. In the presented mini-review, the history of MRSA in the medical service and modern warfare is highlighted. To allow rapid diagnosis, various molecular diagnostic point-of-care solutions are available. Most evaluation studies, however, are focused on screening swabs rather than clinical materials and evaluation data from harsh environments are widely lacking. Accordingly, studies with complex sample materials under difficult environmental conditions, e.g., in the desert or in the tropics, are desirable to close this gap of knowledge regarding the diagnostic reliability of such modern molecular point-of-care devices.

In fish stock assessment, two approaches have been used to collect data: Fisheries independent survey and fisheries survey. Fisheries independent survey provides scientific information on species composition, catch rate, density, distribution, standing stock biomass and biological information of certain species while fisheries survey supplies primary data for a wide variety of statistical analysis of fisheries performance. In Vietnam, fisheries survey was first developed by project “Assessment of the Living Marine Resources in Vietnam” with the support of DANIA since 1998 as the pilot study in 11 coastal provinces with the purpose of establishing the fisheries statistical system in Vietnam. After the pilot stage, it has been extended to all of 28 coastal provinces and worked effectively since 2000. In 2006, when the project ended, the fisheries statistical system collapsed due to no finance support to continue. Since July 2014, the fisheries data collection network has been recovered with the collaboration of Directorate of Fisheries, Research Institute for Marine Fisheries and Provincial Departments of Capture Fisheries and Marine Resources Protection. The survey design was the logbook base with applying the sampling in space and in time method. This is an overview of the capture fisheries survey in Vietnam with its limitations and challenges.

Published: June 2018

ABSTRACT Objective: Hand hygiene plays a key role in the prevention of healthcare-associated infections. Therefore, this study aims to analyze nurses’ adherence to hand hygiene and identify intervention strategies to improve this procedure. Method: Integrative literature review, using the Cochrane methodology, to answer the following question: “What is the level of effectiveness of training in improving nurses’ adherence to hand hygiene?”. Results: Studies show that nurses’ adherence to hand hygiene has increased from 42.9% to 61.4% (p<0.001), or even from 63% to 76% (p<0.005) after a specific training intervention. Conclusion: After training, nurses’ adherence to hand hygiene improved, particularly when compared to the other professionals involved. Despite its simplicity, the implementation of a training program and its subsequent follow-up have a positive on nurses’ attitudes and adherence to hand hygiene.

Published: June 2018

ABSTRACT Wood demand is increasing in quality and quantity, and economic studies are fundamental to analyze the feasibility of forest projects. These researches are in line with management and silvicultural studies, highlighting growth and yield modeling. This paper proposes an economic evaluation of implementation of African mahogany stands in Brazil under different perspectives of forest management. Data are from plantations ranging from 1.1 to 15 years old in different Brazilian regions. Financial analysis was undertaken using Net Present Value (NPV), Internal Rate of Return (IRR) and Equal Annual Equivalent (EAE) for a 20-year period considering three thinning management regimes (A - unthinned, B - one thinning at age 10 years remaining 150 trees ha-1 and C - two thinnings, first at age 8 remaining 150 trees ha-1 and second at age 15 years remaining 75 trees ha-1) considering an initial density of 278 trees ha-1. A Monte Carlo simulation was performed considering six risk variables. Results showed that the discount rate is the variable that most influences the viability of the project. All site indexes in all management regimes lead to a feasible financial return, with NPV values ranging from 25,053 to 125,780 Brazilian reais per hectare, being regimes B and C the best ones. The probability for an unfeasible investment is almost zero, highlighting African mahogany as a great forest investment opportunity, providing high interest rates values (14% to 25%), superior to most available market rates of return.

Considering the Role of the Teacher: Buber, Freire and Gur-Ze’ev
Authors: Guilherme Alexandre , Morgan W. John
Published: June 2018

Abstract: This article considers three different concepts of the role of the teacher. Buber understands the teacher as the builder-teacher of a dialogical community playing a fundamental role in the character formation of individuals. Freire develops this notion, adding a political tinge, and argues for a political-teacher who plays a central role in the formation of critical individuals and in the liberation of the oppressed. Gur-Ze’ev is critical of Freire and defends the improviser-teacher, who is always critical and encourages criticisms, but without reference to utopias. The article compares and assesses critically these concepts of the role of the teacher; and indicates the implications of adopting them, not only for education, but also for society more generally.

Abstract In this study, we evaluated the ovicidal and larvicidal activity of protein preparations obtained from Cassia fistula L. and Combretum leprosum Mart. leaves on the gastrointestinal parasites of goats. Protein preparations were obtained after the extraction of C. fistula L. and C. leprosum Mart. leaves, followed by protein fractionation (with ammonium sulfate saturation percentages of 30%, 30%-60%, and 60%-90%) and dialysis, which resulted in protein fractions (called F1, F2, and F3, respectively). The fractions were evaluated by egg hatching (the eggs were recovered in stool samples from naturally infected goats) and larval development tests. The results reveled that the inhibition of hatching of eggs caused by the protein fractions of C. fistula (38%) were similar to that of the control drug, thiabendazole. In addition, the fractions of C. fistula caused significant inhibition (61-69%) of larval development also. However, C. leprosum did not reveal significant inhibition of egg hatching and larval development. We conclude that C. fistula L. showed better ovicidal and larvicidal activity against endoparasites.
Performance of a pile foundation in soft soil
Authors: Xiao Junhua , Zhao Xihong
Published: June 2018

This paper presents the field instrumentation on the pile foundation of the 492 m high Shanghai World Financial Centre (SWFC), which is supported on steel pipe piles of 700 mm dia. and 60 m long in the deep, soft soil of the Yangtze River delta. During the whole construction stage, the performance of the pile foundation, including pile load, contact pressure, pore-water pressure and settlement, was intensively and successfully investigated. The monitored data indicated that the force acting on the pile, in stark contrast to the design assumption of loading equally, was quite uneven; the contact pressure inevitably was produced once the settlement developed; the pore-water pressure reflected the water head from the underground confined water; the foundation settlement was 127 mm and the settlement difference was 6 mm between the opposite sides of the raft. The analytical work demonstrates the influence of the various factors contributing to the observed behaviours of the foundation, and the safety of the observed foundation is still under control. For the first time, in situ testing of the pile foundation of a super-tall building embedded in deep, soft soil was conducted; the results provide a comprehensive insight into the working performance of a pile foundation.
Probabilistic investigation on defective jet-grouted cut-off wall with random geometric imperfections
Authors: Pan Y. , Liu Y. , Chen E. J.
Published: June 2018

This study examines the effect of geometric imperfections arising from variations in both the diameter and orientation of jet-grouted columns on the water-tightness of a jet-grouted cut-off wall. A three-dimensional discretised algorithm is used to detect and measure the discontinuities in the wall. A statistical evaluation of the gross flow rate through the cut-off wall with random flow-through pathways is carried out using Monte Carlo simulations. Based on the statistical results, a dimensionless design chart is proposed which can help engineers to devise safe and economical wall designs through trade-offs among various parameters such as target diameter, column spacing and number of rows.

Published: June 2018

The paper presents the results of the study of coping specifics in adolescents at risk of self-injurious and suicidal behavior (N=174). We hypothesized that profiles of coping depended on the types of actual stress. We took into consideration the following types of stressful circumstances: parental divorce, death of relatives or loved ones, conflict with parents, serious somatic disease, academic failure and school problems, unrequited love, other, no actual stress. We discovered both common and stress-specific coping strategies. One of the common coping strategies is avoidance that is used more often in all stressful situations. Moreover, the sample was distinguished by increasing low-level strategies, rather than decreasing high-level strategies (such as planning or reappraisal). Applications to prevention measures are discussed.

Published: June 2018

The presence of a single nodal metastasis has significant prognostic and treatment implications for patients with head and neck cancer. This study aims to investigate whether dual-energy computed tomography (DECT)-derived iodine content and spectral attenuation curve analysis can improve detection of nodal metastasis in oropharyngeal carcinoma. Eight patients with newly diagnosed oropharyngeal squamous cell carcinoma and pathologically proven nodal metastatic disease (n = 13 metastatic nodes; n = 16 nonmetastatic nodes) who underwent contrast-enhanced DECT of the neck were retrospectively evaluated. DECT-derived iodine content (mg/mL) and monoenergetic attenuation values at 40 keV and 100 keV were obtained via circular regions of interest within metastatic and nonmetastatic cervical lymph nodes. Iodine content was significantly lower in metastatic nodes (0.96 ± 0.28 mg/mL) than in nonmetastatic nodes (1.65 ± 0.38 mg/mL; P = .002). Iodine spectral attenuation slope was significantly lower in metastatic nodes (1.33 ± 0.49 mg/mL) than in nonmetastatic nodes (1.91 ± 0.64 mg/mL; P = .015). A nodal iodine threshold of ≤1.3 mg/mL showed a sensitivity of 84.6% and a specificity of 75.0%, with an area under the curve of 0.839, P < .0001. At a threshold value of ≤1.95 for nodal spectral attenuation slope, an optimized specificity of 92.3% and specificity of 50.0% was achieved, with an area under the curve of 0.68 (P = .049). DECT-derived quantitative iodine data and spectral attenuation curves may improve the diagnostic accuracy of computed tomography for nodal metastasis in patients with squamous cell carcinoma of the oropharynx.
Indigenous Rights and Multilevel Governance: Learning From the Northwest Territories Water Stewardship Strategy
Authors: Latta Alex
Published: June 2018

States’ increasing recognition of Indigenous rights in the realm of natural resources has led to a variety of co-management arrangements and other forms of melded authority, evolving over time into increasingly complex governance relationships. This article takes up such relationships within the analytical frame of multilevel governance, seeking lessons from the experiences of Indigenous involvement in water policy in Canada’s Northwest Territories (NWT). It examines the way that effective collaboration in resource governance can emerge within the space of tension between evolving Indigenous rights regimes and the continued sovereignty of the state. At the same time, the analysis raises questions about whether multilevel governance can contribute to meaningful decolonization of relationships between settler states and Indigenous Peoples.
Allocation of structural funds before and after the brexit: An exercise in the economics of cake-sharing
Authors: Heijman Wim
Published: June 2018

What impact has the Brexit on the allocation of money from the structural funds? As the UK is a net contributor to the EU budget, the budget for Structural and Cohesion Policy will shrink. This will have an impact on the allocations of the structural funds to the remaining members of the EU. In order to estimate the allocation of the structural funds to the remaining EU members an allocation model is developed in this article. It appears that the model results do not only show the sharing of the cake, but also the size of it.

Published: June 2018

This research aimed to uncover collective memory denial of the victims’ families of Students who died in Trisakti and Semanggi Tragedy 1998-1999. We described how this pattern of collective memory denial works. This research used the qualitative approach to the instrumental case study. The participants were three mothers of students who died in Trisakti and Semanggi tragedy. We carried out interviews and field note as data collecting technique. This data was analysed using thematic analysis technique. The result showed that there is a denial of collective memory which is experienced by victims’ families of students who died at Trisakti and Semanggi tragedy. The pattern is formed systematically, orderly, and deliberately. This denial showed that the government deliberately prevented the people to remember this tragedy. Collective memory denial causes so many negative effects, such as conspiracy of silence on the people and second victimization for victims’ families. Moreover, these effects included the form of prejudice, mistrust, aversion, and vengeance between the people. When social sharing continuously assembles, it will finish the emotional problem of a negative event. On the other hand, social sharing will develop subjective well-being of the people in that community, not only in short-term but also in long-term. Collective memory which is healthy distributed, motivates the community to discuss, express, and cope the painful trauma in the past.
Linking a Total Ankle Arthroplasty Registry to Medicare Inpatient Claims without Unique Identifiers
Authors: Raman Sudha R. , Hammill Bradley G. , Queen Robin M. , Adams Samuel B. , Curtis Lesley H.
Published: June 2018

Background:

Linking clinical registries to administrative claims data enables researchers to capitalize on the specific strengths of each data source with respect to the depth, breadth, and completeness of information. The objectives of this study were to link a health-system-based orthopaedic surgery registry to U.S. Medicare claims data without the use of unique identifiers and to assess the representativeness of the linked records.

Methods:

The registry included clinical data for patients ≥65 years of age who underwent elective, inpatient total ankle arthroplasty (TAA) in a single health system during the period of 2007 through 2012. Registry participants were identified within the Medicare data by linking registry procedures to TAA procedures within the claims data using a combination of procedure date, patient date of birth, and patient sex. We assessed the representativeness of the linked records by comparing them to both unlinked registry records and unlinked Medicare records for TAA procedures. Additionally, we described the availability of postsurgical data for linked records.

Results:

Of 360 TAA registry participants ≥65 years of age, 280 (77.8%) were matched to a Medicare record; 250 (89.3%) of those 280 participants were matched on the basis of a linking rule that required an exact match for procedure date, date of birth, and sex. The 280 linked records comprised 5.5% of all Medicare TAA procedures among beneficiaries ≥65 years of age enrolled in the fee-for-service Medicare program (n = 5,070). Compared with linked records, unlinked records were more likely to be for patients 65 to 69 years old, but the 2 groups were similar in terms of sex, body mass index, and availability of clinical measurements. Of the linked records, 214 (76.4%) had ≥3 years of postoperative follow-up claims data.

Conclusions:

Linkage without unique patient identifiers between an orthopaedic registry and Medicare claims data is feasible, allows for assessment of representativeness, and creates a unique resource of longitudinal data for research.
Laboratory Tests for Diagnosis of Chronic Periprosthetic Joint Infection Can Help Predict Outcomes of Two-Stage Exchange
Authors: Dwyer Maureen K. , Damsgaard Christopher , Wadibia Jason , Wong Gordon , Lazar Damien , Smith Eric , Talmo Carl , Bedair Hany
Published: June 2018

Background:

Although 2-stage exchange arthroplasty is the most effective treatment among available strategies for managing chronic periprosthetic joint infection (PJI), rates of its success vary greatly. The purpose of our study was to examine whether objective measurements collected at the time of the diagnosis of PJI could be used to identify patients at risk of failure of 2-stage exchange.

Methods:

We identified 205 patients across 4 institutions who underwent 2-stage exchange arthroplasty for the treatment of PJI following total hip or total knee arthroplasty. Demographic, surgical, and laboratory data were obtained for each patient from their medical chart. Laboratory values included serum erythrocyte sedimentation rate (ESR), serum C-reactive protein (CRP) level, synovial fluid white blood-cell (WBC) count and neutrophil percentage, synovial fluid and/or tissue culture, and Gram stain. Patients who underwent revision surgery for recurrent infection were considered to have failed the 2-stage procedure. Demographic, surgical, and laboratory variables were compared between the 2 groups. Receiver operating characteristic (ROC) curves were constructed to determine threshold cutoffs for significant laboratory values. Risk ratios and 95% confidence intervals were calculated.

Results:

Overall, 2-stage exchange was unsuccessful for 27.3% of the patients. Preoperative serum ESR (p = 0.035) and synovial fluid WBC count (p = 0.008) and neutrophil percentage (p = 0.041) were greater in patients with recurrent infection. ROC curve analysis revealed a threshold of >60,000 cells/μL for synovial fluid WBC count, >92% for synovial fluid WBC neutrophil percentage, and >99 mm/hr for serum ESR. Failure of 2-stage exchange was 2.5 times more likely for patients with an elevated preoperative synovial fluid WBC count, 2.0 times more likely for those with an elevated preoperative synovial fluid WBC neutrophil percentage, and 1.8 times more likely for those with an elevated preoperative serum ESR.

Conclusions:

Our results demonstrated that a greater number of patients in whom 2-stage exchange arthroplasty ultimately failed had a preoperative synovial fluid WBC count of >60,000 cells/μL, a synovial fluid WBC neutrophil percentage of >92%, or a serum ESR of >99 mm/hr. Patients with elevated laboratory values had 1.8 to 2.5 times the risk of treatment failure. These data can serve as a clinical guideline to identify patients most at risk for failure of 2-stage exchange.

Published: June 2018

We introduce a novel well-logging method for determining more-accurate total porosities, fluid volumes, and kerogen volumes in shale-gas and shale-tight-oil wells. Improved accuracy is achieved by self-consistently accounting for the effects of light hydrocarbons and kerogen on the log responses. The logging measurements needed to practice this method are bulk densities, nuclear-magnetic-resonance (NMR) total porosities, and total-organic-carbon (TOC) weight fractions. The TOC weight fractions and the matrix densities, which are used to interpret the bulk density measurements, are both derived from geochemical-tool measurements.

Most unconventional shale-gas and shale-tight-oil reservoirs contain some nonproducible immobile hydrocarbons. When immobile hydrocarbons are present, our method requires prior knowledge of in-situ total water volumes. The water volumes can be estimated from dielectric-tool measurements. In special cases (e.g., in some mature shale-gas reservoirs) where no immobile hydrocarbons are present, a dielectric tool is not needed. In such cases total water volumes are outputs of the method.

We discuss the response functions in shale reservoirs for measurements of bulk densities, NMR porosities, and TOC weight fractions and derive exact self-consistent solutions to the response equations. The algebraic solutions are used to compute shale total porosities, fluid volumes, and kerogen volumes. The predicted shale total porosities and fluid volumes are corrected for light-hydrocarbon effects on the measured bulk densities and NMR porosities and for kerogen effects on the bulk densities. It is shown that significant errors can be made in log-derived shale total porosities if NMR porosities or density-log porosities are assumed to represent true-shale porosities without applying proper corrections.

We discuss the application of the method to the analysis of logging data acquired in a mature shale-gas well drilled in the Marcellus Shale in the northeastern United States and to data acquired in a shale-tight-oil well drilled in the Permian Basin in west Texas. A multifrequency dielectric tool is used to determine in-situ total water volumes in the tight oil well. The mature shale-gas reservoir does not contain immobile hydrocarbons, and, therefore, dielectric-logging measurements were not needed in this well. The results in both wells are shown to compare favorably with core data.

Doğal
kaynakların kullanımı ile ilgili işlemlerin başında gelen madencilik
faaliyetleri, işletmenin türüne ve büyüklüğüne bağlı olarak farklı boyutlarda
gelişen çevresel etkilere ve bozulmalara neden olmaktadır. Bu etkilerin
başında, madencilik faaliyetleri sırasında ve sonrasında ciddi ekolojik riskler
oluşturan Asit Maden Drenajı (AMD) gelmektedir. AMD, sülfür içeren (özellikle
pirit, pirotin ve kalkopirit) cevher atıkların, tipik olarak hava (oksijen) ve
su içeren ortamlarda, yeraltı suyu, yağmur ve akıntı nedeniyle oksitleyici
koşullara maruz kalması sonucu meydana gelen asit oluşumunu ifade etmektedir. Bu
çalışmada, Gümüştaş Madenciliğe ait işletme sahası, cevher stok ve atık
depolama alanlarında AMD oluşumunu belirlemeye yönelik işlemler yapılmış ve AMD
gelişme potansiyeli ile muhtemel AMD gelişmesi durumunda alınacak tedbirler
ortaya konmuştur. Maden işletme alanı, Eosen yaşlı andezit ve bazalt ile bu
kayaçların piroklastitlerinden oluşan Alibaba Formasyonu içerisinde yer
almaktadır. Yapılan çalışmalarda pH değerleri tüm örneklerin I. sınıf kıta içi
kaynak suyu özelliğinde olduğunu, macun pH ve sülfid (S-2) değerleri
ise maden işletme sahasında AMD potansiyelinin bulunmadığına işaret etmektedir.
Ana ve iz elementlerin düşük mobiliteye sahip olması ise bu durumu destekler
niteliktedir. Tüm örneklerde Net Nötralizasyon Potansiyeli (NNP) değerlerinin 20 kg CaCO3/ton’dan ve Nötralizasyon
Potansiyel Oranı (NPO) değerlerinin 2’den büyük olması da potansiyel asit üretmeyen
karakterde olduğunu göstermektedir. S-2 değerlerinin çok düşük
olması, söz konusu alanda kısa dönem içerisinde asit kaya drenajı potansiyeli gerçekleşmeyeceğini
işaret etmektedir. Buna ek olarak, stok sahasını geçirimsiz hale getirmek için
50 cm kalınlığında geçirimsiz kil serilerek sıkıştırılmış, oluşan düşey profil
sonlu eleman ağ sisteminde modellenerek su deşarjları belirlenmiştir. Yapılan tüm
çalışmalar neticesinde maden işletme sahasında kısa sürede AMD oluşumu
beklenmediği sonucuna varılmıştır. Ancak, maden işletme alanında, uzun
sürelerde muhtemel AMD oluşumundan kaynaklanacak çevre kirliliği, yapılan
çalışma kapsamında alınacak tedbirlerle önlenmiş olacaktır.

Core Ideas

Positive effect of genotype and N on yield and protein in grains and meal.

No effect of genotype and N on concentration of oil in grain.

High oleic genotypes showed higher protein concentration of grains and by‐products.

Nitrogen increased the protein /oil ratio of the grains.

Nitrogen improved the quality of sunflower by‐products.

Sunflower (Helianthus annuusL.) conventional (CONV) and high oleic (HO) genotypes differ in yield and quality. Nitrogen affects grain yield, quality, and by‐products protein concentration. The objective was to evaluate the effect of genotype and N on grain yield, oil (OG) and protein (PG) concentration in grain and in by‐products (PM). The effect of genotype was evaluated in Exp. 1 with 7 CONV and 7 HO hybrids, at two planting dates (PD early and late). The effect of N (Exp. 2) was evaluated in 10 locations (3 with CONV and 7 with HO), under six N rates (0, 30, 60, 90, 120, and 150 kg N ha−1). We determined yield, OG, PGand PM. For the early PD of E1, yield was higher in HO than CONV genotypes (3822 kg ha−1vs. 3495 kg ha−1). In Exp. 2, N increased yield in 50% of the locations (HO: 586; CONV: 597 kg ha−1). In Exp. 1, genotype did not affect OG, but PGwas higher in HO than in CONV ones (18.0 vs. 16.8%, respectively). In Exp. 2, N did not affect OG, but increased PGin both types of genotypes. Consequently, PG/OGratio increased with N rates. The higher PG, was also reflected in higher PM(44.0% HO and 38.8% CONV, respectively). Increases of 2.5% points in PGresulted in increases of 5.6 in PM. Therefore, the application of N would allow obtaining high yields and PGwithout detrimental effects on OG, improving the quality of grains and by‐products.

Core Ideas

We reviewed aboveground biomass and total N content of hairy vetch–cereal rye mixtures vs. monocultures.

Overall, mixtures produced equivalent or more biomass and N content as monoculture species.

Environmental and cropping system factors affected relative productivity of mixtures.

Mixtures performed better in coarse‐textured soils and following corn harvest.

With increasing GDD, mixtures productivity decreases relative to hairy vetch, but increases relative to cereal rye monocultures.

Agroecosystem services from cover crop mixtures are linked to aboveground biomass and total N content (kg ha−1). Reported values in the literature, however, vary for aboveground biomass and total N content of cover crop mixtures compared with monocultures. We conducted a meta‐analysis using results from 55 site‐years from 21 studies conducted in the United States to examine biomass and N content of hairy vetch (Vicia villosa Roth)–cereal rye (Secale cereale L.) mixtures compared with respective monocultures. Overall, hairy vetch–cereal rye mixtures produced 63 and 21% more biomass compared with hairy vetch and cereal rye monocultures, respectively. The N content of hairy vetch–cereal rye mixtures was 150% greater than that of cereal rye monocultures. When the proportion of hairy vetch seeds (by weight) exceeded 46% of the mixture, the mixtures accumulated equivalent or more N than the greatest yielding monocultures (usually hairy vetch). Compared with monocultures, a more consistent positive response of mixtures on biomass and N content was found on coarse‐textured soils and following corn (Zea mays L.) rather than soybean [Glycine max (L.) Merr.] harvest. With increasing growing degree days (GDD), the biomass and N content of mixtures decreased relative to hairy vetch monocultures but increased relative to cereal rye monocultures, suggesting better performance of hairy vetch at higher GDD. We conclude that hairy vetch–cereal rye mixtures can produce equivalent or more biomass than both monocultures and accumulate as much N as hairy vetch, and that the relative productivity of mixtures depends on soil type, previous crop, seeding proportion, and GDD.
Modeling Deficit Irrigation of Maize with the DayCent Model

Core Ideas

A new version of the DayCent model was capable of simulating the responses in maize‐dominated agroecosystems under water‐deficit conditions.

The accuracy of DayCent‐simulated GLAI, biomass, SWC, and yield was similar to that observed with more complex models.

There was no significant difference in the major output variables when the stress coefficient, Ks, was calculated by the FAO method or the original DayCent method.

A promising solution to help close the gap between water demand and supply in semiarid regions is deficit irrigation strategies that use less water but aim to increase crop yield per unit of water applied. Dynamic models can be used to assess the impacts of deficit irrigation and to support decision‐making. In this study, we evaluated the capability of a new version of the DayCent agroecosystem model to model crop growth, yield, and water use in response to water‐deficit conditions resulting from different deficit irrigation strategies employed in three field experiments with maize (Zea mays L.) in eastern Colorado. Overall, the DayCent model with improved algorithms for plant canopy development provided accurate estimates of green leaf area index (GLAI) for full and deficit irrigation treatments, though the method tended to overpredict the GLAI during the late vegetative growth period in the deficit irrigation treatments. Simulated soil water content (SWC), biomass, and grain yields compared well with the field measurements. We tested the drought stress coefficient (Ks) method in the FAO Irrigation and Drainage Paper No. 56 as an alternative to the original DayCent method for estimating drought stress. There were only marginal differences between the two Ks methods in predicting the major output variables in DayCent, but the FAO method is simpler and easier to parameterize. Overall, the DayCent model can simulate the responses in agroecosystems with maize under water deficit conditions and could be used as a guide for applying deficit irrigation strategies for water savings.
