PUBLIC ENTERPRISES LEGAL ASPECTS OF LEGAL RESPONSIBILITY
Authors: Shepeleva Dina Viktorovna
Published: January 2019

We consider legal aspects of legal responsibility of public enterprises. Legal liability for violations of the financial activities of public enterprises can be administrative, civil, financial and even criminal. Analysis of the responsibility of public enterprises allows us to note that at the legislative level, the mechanism of responsibility for violations of the order of financial activity, which is associated with the provision of financial transactions for the transfer of profits, the implementation of budget borrowing, ensuring the efficiency of the use of the property of the enterprise, providing the owner and the authorized body of the necessary information, is not fully provided. It should be noted that for the optimal participation of public entities in economic relations, unitary enterprises implement government orders, carry out government procurement, interacting both with potential contractors and with the owner – the state or public legal entity, including through the Internet. But not always, this kind of activity is going on without violations.

Published: January 2019

We consider development of modern criminal legislation features in the anti-corruption sphere. The urgency of the fight against corruption in the Russian Federation and the difficulties standing in its way are emphasized. Noted the specificity of the Russian legislation in the anti-corruption sphere, which consists in the fact that the modern Russian criminal law mechanism of combating corruption is firmly based on international legal acts. The main stages of development and formation of modern anti-corruption legislation, its connection with international law are considered. The role of legal norms in strengthening the security of the state, increasing its authority in the world is revealed. A large number of sources of corruption law are analyzed, including the Criminal Code of the Russian Federation, Federal laws, the Decision of the Supreme Court of the Russian Federation, Decrees of the President of the Russian Federation. Changes made to the legislation in different years concerned the subject structure, the minimum size of a bribe, nature of commission of crime, etc. In the course of the analysis of anti-corruption norms of criminal law traced their relationship with the non-criminal legislation in force in this area, noted their mutual influence. It is concluded that the current anti-corruption criminal legislation has been formed in the Russian Federation, but the process of its development due to the ongoing socio-economic transformations of society is not completed. The necessity of an effective legal mechanism regulating public relations arising in the case of a corruption-related crime is noted.
CRIMINOLOGICAL ASPECTS OF THE PREVENTION OF CRIMES COMMITTED BY PERSONS WITH NEGATIVE CHANGES IN MENTAL ACTIVITY
Authors: Ignatenko Evgeniy Aleksandrovich , Chelnokov Nikita Evgenevich
Published: January 2019

We examine the question of prevention of crimes committed by persons with negative changes in the psyche. The relevance of the topic is confirmed by the fact that in modern conditions, preventive activities against crimes of persons with mental disabilities has acquired high importance and has become the main concept of general and forensic psychiatry, but the lack of scientific research on the prevention of crimes committed by persons with mental disorders, has a negative impact on the fight against crime. The effectiveness of the fight against crime largely depends on organizational and methodological prerequisites. Prevention of crimes committed by persons with negative changes in mental activity has an integrative nature and is possible only with the comprehensive development of tactical methods of preventive measures, criminological methods of prevention of crimes committed by persons and the development on this basis of practical recommendations to improve preventive activities. Prevention consists of two main areas: socially oriented and biologically based measures. We propose to emphasize the special field of prophylaxis and prevention measures against crimes – socio-psychiatric prophylaxis, justifying it by the fact, that prophylaxis is a complex measure. We draw a conclusion that it is possible to ensure sustainable and effective preventive work only with the coordinated mutual work of doctors and law enforcement officers, first of all, the internal affairs bodies, as well as social workers.

Este artigo toma o conceito de montagem operado na filosofia e nas artes por Deleuze e Didi-Huberman, realizando certa extração para compor uma problematização da montagem do pensamento e da escrita em educação. Toma-se, assim, a montagem como procedimento filosófico, gesto político e criação artística. Quando escrevemos em educação, sobre educação, para educadores, produzimos imagens de pensamento por meio de tais produções. Interessa, então, apreender os funcionamentos desse conceito para operá-lo nos deslocamentos possíveis do que se pensa e se escreve em educação, em especial, na escrita acadêmica. Entendemos que tomar a escrita como montagem do pensamento poderia operar como certa problematização do pensamento dogmático em educação.

Published: January 2019

A pesquisa objetivou compreender as percepções juvenis acerca do significado da experiência socioeducativa de internação, medida privativa de liberdade, que se propõe a ser educativa e socializadora. Com a metodologia da história oral biográfica coletou-se sete entrevistas livres como fontes primárias. Os resultados apontaram característica acerca do perfil dos jovens - defasagem escolar, ingresso precoce no mercado de trabalho, baixa renda, desagregação familiar e rescendência infracional - e  exprimiram cinco categorias que problematizam a experiência da internação - violência sofrida, identidade infratora, perspectivas e planos dos jovens, código de ética, significado da internação. A discussão, realizada mediante a análise de conteúdo, constatou percepções negativas referentes à socioeducação e educação na internação associada à perda de tempo e prevalência do caráter punitivo em detrimento do educativo, já que o disciplinamento coercitivo promovia clima pouco amistoso sob a tônica da violência e a educação era negligenciada e relegada plano inferior de importância.

Published: January 2019

In clinical laboratories the major quantity of errors regarding blood analyses occurs in the pre-analytical phase. Pre-analytical conditions are key necessary factors to maintain the high quality of specimens, to limit day-to-day and batch variations and to guarantee the absolute reliability and accuracy of clinical results and related diagnoses. The quality of the serum samples would have to be very high in order to avoid interferences due to hemolysis, preventing measurement errors. In addition, the quality of blood should be always monitored in a fast way to identify inadequacies and guarantee their complete usability in transfusion procedures. In a near future the solution could be supplying laboratories with smart and portable devices able to rapidly perform quality tests for every samples. Electrical impedance has a relevant potential in analyzing and monitoring blood quality. In this context, we propose a new simple impedance-based biosensor as a possible solution in the pre-analytical phase to efficiently perform fast impedance measurements, useful indicators to check the quality of the samples, ensuring the reliability of results and preventing laboratory errors. This sensor has been applied for the discrimination of different blood components, the identification of hemolysis in serum and the evaluation of blood consistency.

Published: January 2019

The automotive industry is currently undergoing far-reaching structural changes. Automobile manufacturers are pursuing intensive scientific research and technological development in the field of alternative drive systems, such as electric powertrains. If electric car batteries are charged with regenerative generated electricity, their emission output is zero (from a well-to-wheel view). Furthermore, electric drives have very high efficiency. At cold temperatures, however, the battery power drops due to energy-intensive loads, such as the heating of the passenger compartment, and this consequently reduces the range dramatically. Therefore, the focus of this research work is external energy supply for the required heat capacity. The auxiliary energy may be generated by renewable energy technologies in order to further improve the CO2 balance of electric vehicles. The paper deals with the design, application, and testing of a biofuel-operated heater to heat the passenger compartment of a battery-powered electric car (a Renault ZOE R240). The practical use of the heating system is analyzed in several test drives, performed during winter 2018. The results as well as the range extension of the electric car that can be achieved by substituting the on-board heating system by the fuel-operated heater are quantified herein.
Monitoring System Based on Phasor Measurement Units with Variable Reporting Rates
Authors: Castello Paolo , Muscas Carlo , Pegoraro Paolo Attilio , Sulis Sara
Published: January 2019

Classical Wide-Area Monitoring Systems (WAMS) are characterized by a hierarchical architecture composed of Phasor Measurement Units (PMUs) and different levels of Phasor Data Concentrators (PDCs). The WAMS, based on synchrophasor technology, was originally designed for transmission systems; nevertheless, with the development of the smart grid paradigm, the benefits of this technology are being extended to the distribution network. Normally, PMUs send measurement data at a high and constant reporting rate to guarantee the monitoring of dynamic events in an electric transmission network. However, the typical communication systems expected to be used by distribution system operators will be generally shared and/or public and, in this case, the bandwidth available among PMUs and PDCs, or among the PDCs and the control centre, is strictly dependent on the type of communication channel used and on the level of network traffic. In this context, a new transmission logic for the transfer of data between PMUs and PDCs, based on the knowledge of the ongoing conditions of the electric grid, can be implemented. The strategy proposed in this paper is to increase the measurement reporting rate only when the electric system changes from a steady-state condition to a dynamic and potentially unsafe one, without modifying the overall accuracy of the PMU measurement process. The risk of losing important information related to a dynamic event is mitigated by sending to the PDC, after the event detection, also measurements relating to pre-trigger time interval in a burst of data packets that allow an insight on the signal evolution.

K-Values-Based Upscaling of Compositional Simulation
Authors: Salehi Amir , Voskov Denis V. , Tchelepi Hamdi A.
Published: January 2019

Enhanced-oil-recovery (EOR) processes involve complex flow, transport, and thermodynamic interactions; as a result, compositional simulation is necessary for accurate representation of the physics. Flow simulation of compositional systems with high-resolution reservoir models is computationally intensive because of the large number of unknowns and the strong nonlinear interactions. Thus, there is a great need for upscaling methods of compositional processes. The complex multiscale interactions between the phase behavior and the heterogeneities lie at the core of the difficulty in constructing consistent upscaling procedures.

We use a mass-conservative formulation and introduce upscaled phase-molar-mobility functions for coarse-scale modeling of multiphase flow. These upscaled flow functions account for the subgrid effects caused by the absolute permeability and relative permeability variations, as well as the effects of compressibility. Upscaling of the phase behavior is performed as follows. We assume that instantaneous thermodynamic equilibrium is valid on the fine scale, and we derive coarse-scale equations in which the phase behavior may not necessarily be at equilibrium. The upscaled thermodynamic functions, which represent differences in the component fugacities, are used to account for the nonequilibrium effects on the coarse scale. We demonstrate that the upscaled phase-behavior functions transform the equilibrium phase space on the fine scale to a region of similar shape, but with tilted tie-lines on the coarse space. The numerical framework uses K-values that depend on the orientation of the tie-lines in the new nonequilibrium phase space and the sign of upscaled thermodynamic functions.

The proposed methodology is applied to challenging gas-injection problems with large numbers of components and highly heterogeneous permeability fields. The K-value-based coarse-scale operator produces results that are in good agreement with the fine-scale solutions for the quantities of interest, including the component overall compositions and saturation distributions.
Evaluation of Terpolymer-Gel Systems Crosslinked by Polyethylenimine for Conformance Improvement in High-Temperature Reservoirs
Authors: Zhu Daoyi , Hou Jirui , Chen Yuguang , Wei Qi , Zhao Shuda , Bai Baojun
Published: January 2019

A terpolymer-gel system using low toxic polyethylenimine (PEI) as the crosslinker was developed for conformance improvement in high-temperature reservoirs. Suitable gelation time (GT), gel strength, and thermal stability could be obtained by selecting PEI molecular weight and adjusting terpolymer concentrations. With the increase of terpolymer concentration, GT decreases and the gel strength increases. However, in this research, the effect of PEI concentration on the gelation performance was much less obvious than that of the polymer concentration. Very low concentrations of sodium chloride (NaCl) can slightly shorten the GT. After critical concentrations were reached, the authors determined that the ions will delay the crosslinking reaction. Moreover, the addition of sodium carbonate (Na2CO3) can also lengthen GT. The gel systems were able to maintain thermal stability at 150°C. Uniformly distributed 3D network microstructures and the small size of the gel-grid pores made the network structure maintain thermal stability. The use of the terpolymer-gel-system gelation mechanism crosslinked by PEI can help petroleum engineers better understand and apply this terpolymer-gel system.

Published: January 2019

For a well production optimization and cost per barrel of oil reduction, it is very essential to have an accurate measurement of well flowing bottom-hole pressure (FBHP) available all the time during the life of the well. It is a common practice follow in the oil and gas industry to run bottom-hole pressure gauges to record FBHP. However, interfering a producing well is an expensive and time-consuming task, involved with production disruptions and safety risks. To address these concerns, numerous mechanistic and empirical models were formulated to predict FBHP. Among these a large number of models were developed under small laboratory scale conditions and are, ultimately, inaccurate when up-scaled to field conditions.

This study presents an intelligent solution by the development of an empirical model to quantify FBHP for a vertical well. The new model is based on the surface production data such as tubing perforation depth, flow rate of oil, flow rate of gas, flow rate of water, API gravity of oil, tubing string internal diameter, well bottom-hole temperature, wellhead surface temperature, and wellhead pressure. The data used to train the proposed empirical model collected from the published sources, which covered practically reasonable values. The proposed model is also validated by testing against new dataset, and the results were then compared statistically with the other methods used in petroleum industry. The results show that the proposed empirical model considerably outperforms reviewed models and delivers the prediction of FBHP with high accuracy.

The novelty of the proposed empirical model is that it depends only on the surface production which makes the prediction of FBHP in a real time. The proposed model is accurate and can serve as a handy tool for the production engineers to forecast the FBHP in a real time.
Change Of BOE Conversion Factor with Reservoir Pressure Depletion - A Case Study Of XYZ Field
Authors: Hasan Shahid M. , Saeed Akhtar M. , Kumar Sharven , Shakeel M. , Shakeel Mariam , Tanveer Atif
Published: January 2019

The objective of this paper is to investigate the impact of BOEs (Barrel of Oil Equivalent) conversion factor for Gas and LPG with reservoir pressure depletion on production and reserves figures with reference to Petroleum Resources Management System (PRMS) guidelines. In general, it is a common practice of E&P (Exploration & Production) companies to use same BOEs conversion factor for Gas (especially wellhead) and LPG throughout the life of reservoir. However it is understood that Gas and LPG composition plays a vital role on conversion factors of BOEs used which has an impact on the wellhead production figures, well head reserves booking, field economical limit and etc.

In this paper, "XYZ" field is considered to evaluate the impact of BOE conversion factor on wellhead gas and LPG. The "XYZ" field is producing gas condensate from HPHT (High Pressure & High Temperature) fractured carbonate and clastic reservoirs in upper Indus basin of Pakistan. The field was discovered in early 1990’s and produced ~ 70 BSCF of gas till to-date. The standard BOE gas conversion factor for "XYZ" field is 5.80 MSCF/STB which gives 1,224 BOEPD on current production data and expected remaining recovery of around 40 MMBOE. The recent BOE conversion factor based on current gas analysis is found to be 4.46 MSCF/STB that translates 1,500 BOEPD and expected remaining recovery of 46 MMBOE based on average reservoir wise BOE conversion factor of 5.13 MSCF/STB.

LPG is based on 70% propane & 30% butane, therefore its fixed composition restrict us to use a BOE conversion factor in the range of 11.60 to 11.84 MT/D.

BOE estimation and results in this paper conclude that the change of BOE factor depend upon the change in gas composition with production history at wellhead and depletion in reservoir pressure.

Based on this working, wellhead production figures, well head reserves booking and etc for XYZ field have been revised. This also dictates the importance of booking these figures at sale condition.

The objectives of this work were to achieve realistic reservoir modeling using seismic inversion volumes, advance petrophysical & rock typing analysis for predictive modeling of reservoir quality sands of Lam Formation. Generation of predictive scenarios for the constructed reservoir model for reduction in uncertainty. Identification of new infill well locations based on the predictive reservoir sand distribution. Reevaluation of in place volumetrics for Lam Formation in Prospect D Field. The methodology adopted to achieve the above results.

The methodology for this work contained the following steps; In the first step seismic inversion was performed on Prospect D Field 3D seismic dataset to obtain volume of clay seismic volumes and facies volume. Petrophysical rock typing combined with the core data analysis was sued to calibrate the inverted volumes by identification of clay typing. The seismic inversion volumes were integrated with the depositional settings of Lam Formation to qualitatively interpret the inverted volumes. Reservoir modeling was performed using seismic inversion facies volumes and petrophysical rock type model to predict and distribute the different depositional facies being controlled by inversion trends. Generation of In place volumes and predictive scenarios for reduction in uncertainty and attributing more predictive strength to the reservoir model.

On the basis of reservoir modeling two (2) prospective areas were observed to show good quality sand bodies which were non-tight and reflected good reservoir properties. The seismic inversion volumes captured the depositional trends within the Lam Formation showing the variation between channel complexes to reservoir quality delta sand bodies. Two (2) to Four (4) infill well locations were identified along with forecasted results which showed positive results based on the delineated prospective areas. The seismic inversion volume results, petrophysical rock typing combined with core data completely changed the field development plan by identifying new prospective areas which were not identified or interpreted previously.
Point-of-Care Measurement of Activated Clotting Time for Cardiac Surgery as measured by the Hemochron Signature Eliteand the Abbott i-STAT: Agreement, Concordance, and Clinical Reliability
Authors: Dirkmann Daniel , Nagy Elisabeth , Britten Martin Walter , Peters Juergen
Published: January 2019

Background: Since inadequate heparin anticoagulation and insufficient reversal can result in complications during cardiopulmonary bypass (CPB) surgery, heparin anticoagulation monitoring by point-of-care (POC) activated clotting time (ACT) measurements is essential for CPB initiation, maintainance, and anticoagulant reversal. However, concerns exist regarding reproducibility of ACT assays and comparability of devices.
Methods: We evaluated the agreement of ACT assays using four parallel measurements performed on two commonly used devices each (i.e., two Hemochron Signature Elite (Hemochron) and two Abbott i-STAT (i-STAT) devices, respectively). Blood samples from 30 patients undergoing cardiac surgery on CPB were assayed at specified steps (baseline, after heparin administration, after protamine administration) with four parallel measurements (two of each device type) using commercial Kaolin activated assays provided by the respective manufactures. Measurements were compared between identical and different device types using linear regression, Bland-Altman analyses, and calculation of Cohen’s kappa coefficient.
Results: Parallel i-STAT ACTs demonstrated a good linear correlation (r=0.985). Bias, as determined by Bland-Altman analysis, was low (-3.8s; 95% limits of agreement (LOA): -77.8 -70.2s), and Cohen’s Kappa demonstrated good agreement (kappa=0.809). Hemochron derived ACTs demonstrated worse linear correlation (r=0.782), larger bias with considerably broader LOA (-13.14s; 95%LOA:-316.3-290s), and lesser concordance between parallel assays (kappa=0.554). Although demonstrating a fair linear correlation (r=0.815), parallel measurements on different ACT-devices showed large bias (-20s; 95% LOA: -290-250s) and little concordance (kappa=0.368). Overall, disconcordant results according to clinically predefined target values were more frequent with the Hemochron than i-STAT. Furthermore, while discrepancies in ACT between two parallel iSTAT assays showed little or no clinical relevance, deviations from parallel Hemochron assays and iSTAT versus Hemochron measurements revealed marked and sometimes clinically critical deviations.
Conclusion: Currently used ACT point-of-care devices cannot be used interchangeably. Furthermore, our data question the reliability of the Hemochron in assessing adequacy of heparin anticoagulation monitoring for CPB.

The clinical features of syphilitic myelitis with longitudinally extensive myelopathy on spinal magnetic resonance imaging: a case report and literature review
Authors: Yuan Junliang , Wang Weixue , Xu Dongmei , Hu Wenli
Published: January 2019

Background: Syphilitic myelitis as a bacterial infection caused by Treponema pallidum, is a very rare manifestation of neurosyphilis. The magnetic resonance imaging (MRI) appearance of longitudinally extensive myelopathy with syphilitic myelitis is not well documented and only a few cases have been reported about its’ clinical features.
Case presentation: Herein, we report a patient who suffered from syphilitic myelitis with symptoms of sensory disturbance, with longitudinally extensive myelopathy with "flip-flop sign" on spinal MRI. This patient performed complete clinical and radiologic recovery after treatment. We also summarized the clinical features of syphilitic myelitis with longitudinally extensive myelopathy from the reported literatures published in English language. A total of 16 articles of 20 cases between January 1987 and December 2018 were identified. Of the 20 patients with syphilitic myelitis, the age of onset varied between 17 and 63 years. Sixteen patients were males (80%). Sixteen patients presented with the onset of sensory disturbance (80%), 15 with paraparesis (75%), 9 with urinary retention (45%). Eleven patients had high risk behavior (55%). Five patients had concomitant HIV infection (25%). Serological data showed 15 patients performed with positive venereal disease research laboratory (VDRL)/ treponema pallidum particle agglutination (TPHA), and 17 patients with positive VDRL/TPHA in cerebrospinal fluid (CSF). Seventeen patients with elevated cells and protein in CSF. On MRI, 16 patients showed abnormal signal intensities involved thoracic spine, 6 involved cervical, and 3 involved both cervical and thoracic spine. There were 3 patients performed with the "flip-flop sign". All the patients were treated with penicillin, and 15 patients were performed with a better prognosis.
Conclusions: Syphilitic myelitis is a relatively rare feature of Treponema pallidum infection. Early definite diagnosis and antibiotic therapy are crucial for minimizing neurological sequelae. Our case also raises awareness of syphilitic myelitis as an important complication of neurosyphilis due to homosexuality, especially in developing countries.
A case report of spontaneously healed isolated posterior inferior cerebellar artery dissection with headache alone
Authors: Kishi Yo
Published: January 2019

Background: Isolated posterior inferior cerebellar artery dissections can cause subarachnoid hemorrhages or infarctions. Surgical treatments for hemorrhagic stroke cases and medical treatments using antithrombotic agents for ischemic stroke cases have been done, whereas there are very few reports on non-stroke posterior inferior cerebellar artery dissections and the treatment strategy for non-stroke cases has not been established. This is the first detailed report on spontaneously healed isolated posterior inferior cerebellar artery dissection with headache alone.
Case presentation: 48 years old healthy male felt severe right-side throbbing headache and came to OIKE Clinic on the fourth day after the onset. MRI studies revealed his right posterior inferior cerebellar artery dissection and showed no infarctions or hemorrhages. He was observed carefully under continuous monitoring of blood pressure and hydrated sufficiently, given analgesic anti-inflammatory agents. Two weeks later, the dissected vessel’s diameter grew up to the maximal size, though the patient’s headache was rapidly improved around that day. Surgical treatments for prevention of subarachnoid hemorrhage were considered but careful conservative therapy continued in accordance with the patient’s strong desire. Gradually the dissection finding had been improving. Four months later, MRI study showed his right posterior inferior cerebellar artery was seen almost normal in size and shape.
Conclusions: If isolated posterior inferior cerebellar artery dissection with headache alone is detected early on, it might be one therapeutic option to undergo the careful conservative therapy with repeated MRI examinations and assessment of the patient’s headache.

Background: Epigenetics underlying refractory epilepsy is poorly understood. DNA methylation may affect gene expression in epilepsy patients without affecting DNA sequences. Herein, we investigated the association between Carbamazepine-resistant (CBZ-resistant) epilepsy and EPHX1 methylation in a northern Han Chinese population, and conducted an analysis of clinical risk factors for CBZ-resistant epilepsy.
Methods: 75 northern Han Chinese patients participated in this research. 25 cases were CBZ-resistant epilepsy, 25 cases were CBZ-sensitive epilepsy and the remaining 25 cases were controls. Using a CpG searcher was to make a prediction of CpG islands; bisulfite sequencing PCR (BSP) was applied to test the methylation of EPHX1. We then did statistical analysis between clinical parameters and EPHX1 methylation.
Results: There was no difference between CBZ-resistant patients,CBZ-sensitive patients and healthy controls in matched age and gender. However, a significant difference of methylation levels located in NC_000001.11 (225806929.....225807108) of the EPHX1 promoter was found in CBZ-resistant patients, which was much higher than CBZ-sensitive and controls. Additionally, there was a significant positive correlation between seizure frequency, disease course and EPHX1 methylation in CBZ-resistant group.
Conclusion: Methylation levels in EPHX1 promoter associated with CBZ-resistant epilepsy significantly. EPHX1 methylation may be the potential marker for CBZ resistance prior to the CBZ therapy and potential target for treatments.
Glyphosate‐Resistant Soybean Response to Micro‐Rates of Three Dicamba‐Based Herbicides

Core Ideas

The impact of simulated dicamba drift on growth and yield of glyphosate‐resistant soybean was similar among dicamba formulations.

The impact of dicamba drift on soybean could be influenced by moisture condition of the environmental field.

Late vegetative or early flowering stage of soybean was the most sensitive growth stage to dicamba drift.

New dicamba‐based herbicides such as Engenia (N,N‐bis‐(3‐aminopropyl) methylamine salt) and XtendiMax (diglycolamine salt) with VaporGrip technology were developed to reduce dicamba volatility and drift; however, there are claims that these products can still volatilize or drift. Field studies were conducted to evaluate glyphosate (N‐(phosphonomethyl)glycine))–resistant (GR) soybean response to micro‐rates (0, 1/1000, 1/500, 1/100, 1/50, and 1/10 of the label rate, 560 g a.e. ha−1) of the two new dicamba products compared with Clarity (diglycolamine salt) applied at three growth stages. The GR soybean [Glycine max (L.) Merr.] was equally impacted by the micro‐rates of all three products as measured by visual injury, height reduction, delayed physiological maturity, and yield reduction. The greatest visual injury (80%), plant height reduction (65%), maturity delay (22 d), and soybean yield loss (96%) was caused by 1/10 of the dicamba label rate when applied at V7/R1 soybean growth stage. In addition, estimation of effective dose for 5, 10, or 20% yield reduction suggested that V7/R1 was the most sensitive soybean growth stage to the three dicamba products. For example, 10% yield reduction occurred when 1.83 to 1.85 g a.e. ha−1 (∼1/300 of the label rate) of Engenia was applied at V2 or R2, whereas, a lower dose of 0.32 g a.e. ha−1 (1/1750 of the label rate) of Engenia caused the same level of yield reduction when applied at V7/R1. Similar doses were estimated for Clarity and XtendiMax; therefore dicamba drift should be avoided at all costs, because GR soybean was equally sensitive to low rates of all three tested products with different formulations or technologies.
Ink Spot of Warm‐Season Golf Course Turfgrasses

Core Ideas

Ink spot is a foliar disease of bermudagrass and zoysiagrass managed as golf course turf.

Curvularia malina, a novel and sterile species, is the causal agent of ink spot.

The turfgrass symptoms of ink spot include distinct, small chocolate‐brown to black spots.

Curvularia malina is the causal agent of ink spot, a foliar disease of bermudagrass and zoysiagrasses used in golf course settings. Distinct, chocolate‐brown to black spots appear in conjunction with high amounts or frequent precipitation events in the southern United States. Foliar symptoms of ink spot consist of small, purplish‐black spots that develop into eye‐spot lesions on the leaves of zoysiagrasses but develop a round‐to‐elliptical lesion on bermudagrass leaves. Older, blighted leaves at the base of the plant cause the chocolate‐brown to black spots observed in the turfgrass sward. Crown and/or root rot has not been associated with ink spot. Isolation of C. malina is highly successful when using leaves of bermudagrass or zoysiagrass exhibiting ink spot symptoms. Curvularia malina is sterile; therefore, confirmation must be made using sequence data of ITS, GPD1, or TEF1. Curvularia malina has been isolated from bermudagrass and zoysiagrass expressing foliar symptoms of ink spot throughout the Gulf Coast region of the United States, which to date, includes Alabama, Mississippi, Tennessee, and Texas.

Information on the water quality impact of perennial warm‐season grasses (WSGs) when grown in marginal lands as dedicated energy crops is limited. We studied how WSGs affected runoff, sediment, and nutrient losses and related near‐surface soil properties to those of no‐till corn (Zea mays L.) on an eroded soil in southwestern Iowa and a center pivot corner in east‐central Nebraska. The experiment at the eroded soil was established in 2012, and treatments included ‘Liberty’ switchgrass (Panicum virgatum L.) and no‐till continuous corn. The experiment at the pivot corner was established in 2013 with ‘Liberty’ switchgrass, ‘Shawnee’ switchgrass, low‐diversity grass mixture, and corn. We simulated rainfall at 63.5 ± 2.8 mm h−1 for 1 h to portray 5‐yr return periods and measured water erosion in spring 2017. Time to runoff start and runoff depth did not differ between WSGs and corn. On the eroded soil, sediment and nutrient losses did not differ between treatments. At the pivot corner, sediment (0.71 vs. 0.15 Mg ha−1) and PO4–P (0.037 vs. 0.006 kg ha−1) losses were five times higher in corn than in WSGs. Near‐surface soil properties did not differ on the eroded soil, but at the pivot corner, wet aggregate stability was four times higher and residue cover was 34% higher in WSGs than in corn. Water‐stable aggregates were negatively correlated with NO3–N and PO4–P losses. Overall, WSGs can improve water quality in marginally productive croplands, but their effectiveness appears to be site specific.
