Community-based management of acute malnutrition (CMAM) in India: a position paper
Authors: Mathur Meeta , Halim Abdul , Gupta Mousumi , Panda Bijayalaxmi , Syed Arish
Published: November 2018

Considering the burden of Severely Acute Malnutrition (SAM) in India and the availability of SAM treatment at facility level, it is operationally not feasible to treat all SAM children. The community- based approach involves timely detection of severe acute malnutrition in the community and the provision of treatment for those without medical complications with ready-to-use therapeutic foods or other nutrient-dense foods at home. Community based Management of Acute Malnutrition (CMAM) is an integrated approach which on one hand focuses on treatment and on the other prevention. CMAM has a key component of community mobilization which is crucial for prevention. The present paper emphasizes the position of CMAM in India in terms of preventive vs curative, integrative approach, multi sectoral engagement, mental health perspective as per the facts available through secondary sources in India and also experiences of CMAM-I phase implemented in Rajasthan. A CMAM programme can be an ideal and well established programme considering the inclusion of different aspects such as alternative feasible solution, convergent action, multi-stakeholders roles and accountabilities.
Analysis of outcome of acute encephalitis syndrome after inclusion of coverage against scrub typhus
Authors: Jha Ruchi , Jaiswal Anil Kumar
Published: November 2018

Background: Acute encephalitis syndrome (AES) has emerged as a major epidemic in Bihar and is associated with high mortality. Owing to the increasing burden of disease and its associated morbidity and mortality, studies were undertaken to evaluate specific etiology of AES. Some studies suggested emergence of scrub typhus as a major cause of AES accounting for about 25% of the cases1. A Standard Operating Procedure (SOP) was developed for treatment of AES cases in Bihar which included addition of Injection Azithromycin (@ 10 mg/kg for 7 to 10 days in case of suspected mycoplasma/rickettsial infection. The objective of the study is to compare the outcome of AES before and after the inclusion of coverage against rickettsial infection.Methods: It is a randomized controlled trial conducted in the Department of Pediatrics, Patna Medical College and Hospital, Patna from January 2016 to August 2018.Results: Total number of patients enrolled in both the groups were 127 and 88 respectively. No significant difference were seen in the baseline socio- demographic characteristics of the two groups. Case Fatality Rate in the 1st group (without inclusion of Azithromycin) was 39.3% while in the 2nd Group (with Azithromycin) was 12.5%.Conclusions: Due to the emergence of scrub typhus as a major etiological factor for AES, inclusion of coverage against it along with measures like widespread immunization against Japanese Encephalitis and prompt management of complications and euglycemia, can result in steady decline in the death rates due to AES.
Size agnostic change points detection framework for random evolving networks
Authors: Miller Hadar , Mokryn Osnat
Published: November 2018

Background: Changes in the structure of observed social and complex networks’ structure can indicate a significant underlying change in an organization or reflect the response of the network to an external event. Automatic detection of change points in evolving networks is rudimentary to the research and the understanding of the effect of such events on networks.

Methods: Here we present an easy-to-implement and fast framework for change points detection in evolving temporal networks. Unlike previous approaches, our method is size agnostic, and does not require either prior knowledge about the network’s size and structure, nor does it require obtaining historical information or nodal identities over time.  

Results: We use both synthetic data derived from dynamic models and two real datasets: Enron email exchange and Ask-Ubuntu forum. Our framework succeeds with both precision and recall and outperforms previous solutions.

Conclusions: The suggested framework enables a smart and fast detection of events that change networks while the keeping track of the networks’ distributions, enabling fast and size agnostic detection of changes. The framework can be utilized to explore the reaction of networks to events by classifying the nature of the reaction with respect to the resulted degree distribution.

Authors: Mathur Akash , Gangopadhyay Devleena , Daga Ashutosh , Saxena Puneet , Malhotra Hemant
Published: November 2018

Thoracic aortic aneurysms (TAA) are rarely symptomatic. A 55 year old male presents with longstanding chronic backache. CXR showed left hilar shadow with collapse of left lung. Considering the CXR findings and with the patient being chronic smoker a strong possibility of carcinoma lung with bony metastasis was kept and further CECT chest was done. The CECT chest was suggestive of a thoracic aorta aneurysm with thrombosis compressing left principal bronchus and its lower lobar branch resulting in distal area of collapse and consolidation of left lower lobe. These findings were further confirmed on CT angiography. The patient was thus diagnosed as a case of descending thoracic aorta aneurysm probably of atherosclerotic etiology with thrombosis. Patient was started on beta blockers and ACE inhibitors along with supportive and symptomatic treatment and was further transferred to the department of CTVS for surgical intervention. Thus, this case report here signifies that possibility of thoracic aorta aneurysm should always be considered in a patient with chronic backache specially in presence of mediastinal shadow on CXR.
LANGUAGE TESTING SYSTEMS IN EUROPE AND IN RUSSIA: REASONS FOR CREATING, PURPOSES AND OBJECTIVES
Authors: Sazonova A. V.
Published: November 2018

At all times, people have sought to objectively control knowledge. In this regard, testing was one of the best solutions: the personal attitude of the examiner cannot affect the grading. The idea of testing as a form of control of knowledge had already appeared in the ancient times. Active development of testing had already been started in the beginning of the XX century.The reasons for elaboration of language testing in Europe are connected, first of all, with the foundation of the European Union. The united economic space required from workers knowledge of foreign languages confirmed by corresponding certificates. After the spread of language testing and the creation of international organizations involved in the development of testing in Europe, it has become possible to unify the language exams of different countries. In Russia there manifested another situation. After the breakdown of the Soviet Union, the Russian language began being perceived in foreign countries as one more foreign language together with German, English or French. Therefore, it was required to create a new system of language testing, which would allow Russian language to integrate into the system of European educational space. When Russian researchers created a language testing system, they used the European experience, but took into account the specifics of the Russian language and the developments that already existed in the Russian methodology. Now we can see, that their experiment has great results. Soon the Russian testing system will hold its twentieth anniversary, and the TORFl system will continue to evolve.In the article the history of test control, the stages of development of linguistic-didactic testing are presented. The reasons of appearance of test systems, the purposes and aims assigned by European researchers and their Russian colleges are considered.

Authors: Pashkova E. A.
Published: November 2018

This article is devoted to the research of linguistic means of realization of «LOVE» concept on the basis of texts of rock songs by Aerosmith band. The article deals with the definition of the concept given in the works of Russian scholars – E. S. Kubryakova, D. S. Likhachev, U.S. Stepanov and others, and analysis of the language means of «LOVE» concept realization in the texts of rock songs. The author examines in detail the explicit and implicit means of this concept realization. The analysis shows that the elements of conversational style in the texts of rock songs contribute to the closer communication of the singer with his fans, make the lyrics more understandable to the recipients, facilitating the implementation of their conceptual content. Slang units in the texts of rock songs help the performer express his attitude to the concept realized; they are dynamic and expressive means of rendering the author’s ideas; they make the lyrics more understandable to the modern generation. The analysis has demonstrated that that the most frequent stylistic means of the «LOVE» concept realization in the texts of rock songs are such means as metaphor, rhetorical question and repetition. The language and stylistic means are used to render the basic idea that love has a significant impact on the inner world of a human being.

ESTIMATION OF SEISMIC WAVES PARAMETERS WITH APPLICATION OF A GENETIC ALGORITHM
Authors: Sultangaleev R. R. , Troyan V. N.
Published: November 2018

A Genetic algorithm (GA) is a very important method for the solution of non-linear problems. The basic steps in GA are coding, selection, crossover, mutation and choice. Coding is a way of representing data  in binary notation. The algorithm must determine the fitness of the individual models. This means that  the binary information is decoded into the physical model parameters and the forward problem is solved. The resulting synthetic data is estimated, then compared with the actual observed data using the  specific fitness criteria. The selection of pairs of the individual models for the reproduction is based on  their fitness values. Models with the higher fitness values are more likely to get the selection than models with low  fitness values. A crossover caused the exchange of some information between the paired models thereby  generating new models. The mutation is a random change of binary state. The condition of the procedure of mutation: if a value obtained by a random number generator is less than a certain threshold value, the  mutation procedure is performed. The last basic step in GA is choice. We choose from each pairs a model,  which has the less fitness function. Then we produce the procedures: the crossover, the mutation and the  choice. This procedure is continued until we obtain the optimal model. We have used the GA for the  estimation of the velocity for the gradient layer. The synthetic seismogram was calculated by the finite- difference method. The obtained results showed a high effectiveness of GA for the seismic waves velocity estimation.

Published: November 2018

Cyclosporine A (CsA), a widely used immunosuppressive drug, exerts nephrotoxic activities, as demonstrated by increased tubulointerstitial fibrosis, inflammation and podocyte damage. Recently, a number of microRNAs expressed in the kidney have been reported to be elevated during renal damage. Our aim was to investigate the effect of CsA on selected microRNAs in the mouse kidney after CsA treatment. Moreover, as heme oxygenase-1 (HO-1, encoded by the Hmox1 gene) was shown to play a protective role during kidney disorders, we assessed whether HO-1 deficiency in vivo influences the CsA-regulated microRNAs’ expression. We have observed that the pro-fibrotic miR-21 and pro-apoptotic miR-34a expression was upregulated in kidneys of HO-1 deficient mice and it was further enhanced by CsA. Concomitantly, the level of anti-fibrotic microRNAs, belonging to miR-29 and miR-200 families, was down-regulated after CsA treatment. Generally, Hmox1 knock-out (Hmox1–/–) animals were more susceptible to CsA treatment, as the mortality rate was 4 out of 9 Hmox1–/– mice, and increased fibrosis (Tgfb2, Pai1), inflammation (Il6) and apoptosis (Cdkn1a-p21) were noticed in the HO-1 deficient kidneys. In summary, our data demonstrate that CsA induces significant changes in the expression of renal microRNAs and emphasize HO-1 deficiency as an important factor contributing to the CsA-mediated renal toxicity.

Adiabatic Thermodyhamics
Authors: Fronsdal Christian
Published: November 2018

This is a review of efforts to discover action principles for Hydrodynamics and Thermodynamics. The work began with a determined attempt to create sources for Einstein's equations that describe continuous matter - as opposed to point particles. This requires a relativistic action principle. This report is mainly about (non relativistic) Adiabatic Thermodynamics, non equilibrium thermodynamics based on the method of Gibbs. The main relations of classical thermodynamics can be derived from an action principle, in the classical global form and in the local form advocated by Callen. The entropy is defined as the negative derivative of the free energy (free energy density) with respect to the volume (density). This is integrated with an action principle for hydrodynamics that was known to Lagrange in 1760. It is strongly limited to irrotational velocity fields, nevertheless it provides the needed Lagrangian for a large part of thermodynamics. This is the subject of the first 3 sections. It includes a brief review of a new theory of mixtures. The most difficult part of the program has been the discovery of Conservative Hydrodynamics with the required four independent degrees of freedom, with general flows. We give an account of the genesis and the structure of this theory, then a tour of recent applications.
Fatigue Design Challenges in Aerospace Industry: Recent Linear and Nonlinear Models
Authors: Pavlou Dimitrios
Published: November 2018

Reliable fatigue design rules affect the proactive identification of safety parameters in aerospace industry. Numerous fatigue crack initiation and propagation models, linear and nonlinear, have been developed for designing purposes or estimation of the remaining life of aging airplanes. Depending on the adopted assumptions, the accuracy varies for different loading histories, loading types, and materials. Semi empirical models are simple but yield significant inaccuracies. Models with better theoretical basis provide better accuracy, but implementation in real conditions is problematic. In the present work, a review of author’s recent fatigue crack initiation and propagation models based on physical mechanisms is presented and improvements are proposed. Verification of the models on test results is provided and discussed.
Meander Microwave Bandpass Filter on Flexible Textile Substrate
Authors: Moradi Bahared , Fernández-García Raul , Gil Ignacio
Published: November 2018

This paper presents an alternative process to fabricate flexible bandpass filters by using embroidered yarn conductor on electronic-textile. The novelty of the proposed miniaturized filter is its complete integration on the outfit, with benefits in terms of compressibility, stretch ability and high geometrical accuracy, opening the way to develop textile filters in sport and medicine wearable applications. The proposed design consists of a fully embroidered microstrip topology with a length equal to quarter wavelength (λ/4) to develop a bandpass filter frequency response. A drastic reduction in size of the filter was achieved by taking advantage of a simplified architecture based on meandered-line stepped impedance resonator. The e-textile microstrip filter has been designed, simulated, fabricated and measured, with experimental validation at a 7.58 GHz frequency. The insertion loss obtained by simulation of the filter is substantially small. The return loss is greater than 20 dB for bands. To explore the relations between physical parameters and filter performance characteristics, theoretical equivalent circuit model of the filter constituent components were studied. The effect of bending of the e-textile filter is also studied. The results show that by changing the radius of bending up to 40 mm, the resonance frequency is shifted up 4.25 MHz/mm.
Novel Dead-Time Compensation Strategy for Wide Current Range in a Three-Phase Inverter
Authors: Lim Jeong-Woo , Bu Hanyoung , Cho Younghoon
Published: November 2018

This paper proposes a novel three-phase voltage source inverter dead-time compensation strategy for accurate compensation in wide current regions of the inverter. In particular, an analysis of the output voltage distortion of the inverter, which appears as parasitic components of the switches, has been conducted for proper voltage compensation in the low current region, and an on-line compensation voltage controller has been proposed. Also, a new trapezoidal compensation voltage implementation method using the current phase is proposed to simplify realizing the trapezoidal shape of the three-phase compensation voltages. Finally, when the proposed dead-time compensation strategy is applied, the maximum phase voltage magnitude in the linear modulation voltage regions is defined to achieve smooth operation even at high modulation index. Simulations and experiments were conducted to verify the performance of the proposed dead-time compensation scheme.

Authors: Khan Zaeema , Karamahmutoglu Hande , Elitas Meltem , Yuce Meral , Budak Hikmet
Published: November 2018

To elucidate dynamic developmental processes in plants, live tissues and organs have to be visualized frequently and for long time periods. The development of roots is studied in depth at a cellular resolution not only to comprehend the basic processes fundamental to maintenance and pattern formation but also study stress tolerance adaptation in plants. Despite technological advancements, maintaining continuous access to samples and simultaneously preserving their morphological structures and physiological conditions without causing damage presents hindrances in the measurement, visualization and analyses of growing organs including plant roots. We propose a preliminary system which integrates the optical real-time visualization through light microscopy with a liquid culture which enables us to image at the tissue and cellular level horizontally growing Brachypodium roots every few minutes and up to 24 hours. We describe a simple setup which can be used to track the growth of the root as it grows including the root tip growth and osmotic stress dynamics. We demonstrate the system’s capability to scale down the PEG-mediated osmotic stress analysis and collected data on gene expression under osmotic stress.
Electrokinetically Forced Turbulence in Microfluidic Flow
Authors: Duffle Willy L. , Lemley Evan C.
Published: November 2018

While laminar flow heat transfer and mixing in microfluidic geometries has been investigated experimentally, as has the effect of geometry-induced turbulence in microfluidic flow (it is well documented that turbulence increases convective heat transfer in macrofluidic flow), little literature exists investigating the effect of electrokinetically-induced turbulence on heat transfer at the micro scale. Using recently observed experimental data, this work employed computational fluid dynamics coupled with electromagnetic simulations to determine if electrokinetically-forced, low-Reynolds number turbulence could be observed in a rectangular microchannel with using Newtonian fluids. Analysis of the results was done via comparison to the experimental criteria defined for turbulent flow. This work shows that, even with a simplified simulation setup, computational fluid dynamics (CFD) software can produce results comparable to experimental observations of low-Reynolds turbulence in microchannels using Newtonian fluids. In addition to comparing simulated velocities and turbulent energies to experimental data this work also presents initial data on the effects of electrokinetic forcing on microfluidic flow based on entropy generation rates.
Type I Almost-Homogeneous Manifolds of Cohomogeneity One—IV
Authors: Guan Zhuang-dan , Orellana Pilar , Van Anthony
Published: November 2018

This is the fourth part of [6] on the existence of K¨ahler Einstein metrics of the general type I almost homogeneous manifolds of cohomogeneity one. We actually carry out all the results in [8] to the type I cases. In part II [14], we obtained a lot of new K¨ahler-Einstein manifolds as well as Fano manifolds without K¨ahler-Einstein metrics. In particular, by applying Theorem 15 therein, we have complete results in the Theorems 3 and 4 in that paper. However, we only have some partial results in Theorem 5 there. In this note, we shall give a report of recent progress on the Fano manifolds Nn,m when n > 15 and N′n,m when n > 4. We actually give two nice pictures for these two classes of manifolds. See our Theorems 1 and 2 in the last section. Moreover, we post two conjectures. Once we could solve these two conjectures, the question for these two classes of manifolds would be completely solved. With applying our results to the canonical circle bundles we also obtain Sasakian manifolds with or without Sasakian-Einstein metrics. That also give some open Calabi-Yau manifolds.

Published: November 2018

The health condition and nutritional status of a pregnant woman have a significant influence on the growth and development of her placenta and the fetus. Mineral components are indispensable for the correct growth and development of a fetus. The study described in this work aimed to determine contents of selected mineral components in placenta tissue and to establish their effect on birth parameters of a neonate. Study results demonstrated that the age of mothers affected contents of Ca and Mn in the placenta, whereas their habit of tobacco smoking in the gestational period affected contents of Ca, P, K, Mg, Fe, and Cu in the placental tissue. It was also shown that high contents of K (Me 2049 mg/kg) and Fe (128.4 mg/kg) in the placental tissue contributed to the correct birth length reached by the neonates (46-54 cm). A significant correlation found between contents of selected minerals in the placenta and anthropometric parameters of neonates points to the necessity of continuing research on the factors which affect contents of these elements in biological tissues as well as their impact on the health status of neonates.

The Quasi Steady State Cosmology in a Radiation Dominated Phase
Authors: Bali Raj
Published: November 2018

Analytical solutions for radiation dominated phase of Quasi Steady State Cosmology in Friedmann-Robertson-Walkar models are obtained. We find that matter density is positive in all the cases (k = 0,-1,1). The nature of Hubble parameter (H) in [0,2] is discussed. The deceleration parameter (q) is marginally less than zero indicating accelerating universe. The scale factor (S) is graphically shown with time. The model represents oscillating universe between the above mentioned limits. Because of bounce in QSSC, the maximum density phase is still matter dominated. The models represent singularity free model. We also find that the models have event horizon i.e. no observer beyond the proper distance rH can communicate each other in FRW mdels for radiation dominated phase in the frame work of QSSC. The FRW models are special classes of Bianchi type I, V, IX space-times with zero, negative and positive curvatures respectively. Initially i.e. at  = 0, the model represents steady model. We have tried to show how a good fit can be obtained to the observations in the framework of QSSC during radiation dominated phase.

Relações de gênero e educação: crítica aos projetos de lei “Escola Sem Partido”
Authors: De Souza Ana Paula Hilgert
Published: November 2018

Na conjuntura política atual, em que a garantia de um estado laico encontra-se ameaçada por interesses políticos de determinados grupos de legisladores da nação, a educação vem sendo cerceada de princípios básicos garantidos pela Lei de Diretrizes e Bases (nº 9.394/96), tais como liberdade de aprender, ensinar, pesquisar e divulgar a cultura, o pensamento, a arte e o saber; pluralismo de ideias e de concepções pedagógicas; respeito à liberdade e apreço à tolerância. O artigo discute o modo como esses três princípios vem sendo negligenciados por concepções político-religiosas através de estratégias políticas de determinados grupos que levantam hoje a bandeira de um ideal propagado como “escola sem partido”. Também reflete o modo como a crítica aos conteúdos escolares, que versam sobre a identidade de gênero e a sexualidade, está atrelada aos objetivos dos adeptos do MESP - Movimento Escola sem Partido.
Acquiring Accurate Reservoir Data During TCP To Maximize Oil Production and Increase ESP Run Life
Authors: Shumakov Yakov , Hollaender Florian , Sarac Sukru , Theuveny Bertrand
Published: November 2018

Impulse testing using a simple drillstem testing (DST) or tubing-conveyed perforating (TCP) string is reinvigorated by employing a bidirectional wireless acoustic telemetry system. Paired with enhanced-functionality downhole test tools, the innovative approach reduces the cost of testing while providing critical data for completion design, reservoir monitoring and electric submersible pump (ESP) sizing.

Over 46% of all the reported premature pump failures today are associated with incorrect equipment selection and pump sizing. It is mainly due to a lack of reliable reservoir information and especially in new wells without any historical production data (Vandevier, 2010).Operating the pump outside its specified range due to incorrect sizing can cause either a severe downthrust or upthrust condition that results in premature wear of the pump stages and reduces the expected life. It is mainly associated with incorrect pump sizing due to a lack of reliable reservoir information. The oil industry has long sought improvements in performing reservoir characterisation and acquiring dynamic reservoir and well data necessary for ESP sizing, especially in new wells without historical production data. The proposed new methodology and a unique impulse testing technique allow acquiring reservoir data for proper pump sizing.

The impulse testing is not a new concept that allows testing the wells using a simple DST or TCP strings with no flow of hydrocarbon at the surface. This allows the cost to be reduced in comparison with conventional DST operations or any other testing methods.

A new impulse testing technique uses bi-directional wireless acoustic telemetry system to acquire real-time bottom hole pressure data and interface with remote-controllable new-generation downhole tools, such as a tester valve, circulating valve, firing head, or fluid sampler, to issue commands and verify tool status. The acquired data credibly represent reservoir pressure, fluid properties, and well inflow performance that can be used for proper pump sizing.

Numerous efforts have been made to investigate transient behaviors with fracture networks. Unfortunately, because of the complexity and the arbitrary nature of fracture networks, it is still a challenge to study transient behaviors in a computationally efficient manner. In this work, we present a mesh-free approach to investigate transient behaviors in fractured media with complex fracture networks. Contributions of properties and geometries of fracture networks to the transient behaviors were systematically analyzed. The major findings are noted: There are approximately eight transient behaviors in fractured porous media with complex fracture networks. Each behavior has its own special features, which can be used to estimate the fluid front and quantify fracture properties. Geometries of fracture networks have important impacts on the occurrence and the duration of some transient behaviors, which provide a tool to identify the fracture geometries. The fluid production in the fractured porous media is improved with high-conductivity (denser, larger) and high-complexity fracture networks.

The aim of the article was to study of the influence of the apparatus “MOXI” as an alternative method for the correction of arterial hypertension and improving the quality of life of patients using acupuncture reflexotherapy. Materials and methods. The study was conducted in 36 patients with arterial hypertension of 1 stage, low risk, with the experience of the disease from 1 to 2.5 years, without taking antihypertensive therapy. The average age of patients was 41.3±2.6 years. The state of the psycho-emotional sphere was assessed by the SAN test. The determination of the general non-specific adaptation reaction according to Garkavi-Kvakina-Ukolova was carried out. Control of blood pressure and pulse, was carried out in the center, and by the diaries of self-control. We calculated the arithmetic mean of blood pressure for the day and week. Baseline blood pressure was 152/106 mmHg when measured at the center and 149/102 mmHg at home. Results. The obtained results indicate that the adaptogenic set of acupuncture points allows you to simultaneous selective regulation of the function of organs and systems according to the principle of segmental and vegetative innervation. After a course of preventive recovery, a statistically significant (p<0.05) normalization of well-being indicators according to the SAN test was noted from 4.0 to 4.6 points, activity from 3.9 to 4.4 points, mood from 3.9 to 4.7 points. All patients showed a pronounced reduction of complaints and autonomic disorders. In addition, we revealed improvement in the functional state of the cardiovascular system. So, systolic pressure decreased from 152±1.5 mmHg up to 134±2.4 mmHg, and diastolic from 106±0.7 mmHg to 82±1.8 mmHg. Conclusions. As a result of the prophylactic treatment, all patients registered a normal type of adaptive response, since the training reaction was detected in 44.4 % of cases, the calm activation reaction was 22.2 %, in the area of increased activation - 33.4 %. The use of the “MOXI” device in the treatment of patients with arterial hypertension of 1 type, with a low level of risk gives a positive therapeutic effect in the normalization of the psycho-emotional state of patients. It normalizes non-specific adaptation reactions of the body, and allows you to achieve a decrease in blood pressure to normal levels.

Information is lacking regarding management of cool‐season perennial grasses for seed production in the southern Great Plains. Our objective was to determine the effect of spring grazing on seed yield of cool‐season perennial grasses grown in the southern Great Plains. Treatments consisting of no spring grazing by beef cattle (Bos spp.), limited spring grazing, and extended spring grazing were applied to ‘Paiute’ orchardgrass (Dactylis glomerata L.), ‘Lincoln’ smooth bromegrass (Bromus inermis Leyss), and ‘Manska’ pubescent wheatgrass (Thinopyrum intermedium subsp. barbulatum (Shur) Barkw. & D.R. Dewey) in 1998 to 2000, and to pubescent wheatgrass alone in 2001. Date of first hollow stem, when elevation of apical meristems became evident, was also determined. Limited vs. no spring grazing led to decreased seed yield in 7 of 10 Species × Year combinations, whereas extended vs. limited spring grazing led to declines in seed yield in six of nine Species × Year combinations. Date of first hollow stem occurred from late March to early April for orchardgrass and smooth bromegrass, and early to mid‐April for pubescent wheatgrass. Seed yield of orchardgrass and pubescent wheatgrass decreased as grazing time after first hollow stem increased. Commercial seed production of smooth bromegrass, which averaged 336 kg ha−1 with no spring grazing, may be feasible in the Southern Plains. However, spring grazing does not appear to be a viable component of seed production systems for cool‐season perennial grasses in the Southern Plains based on the likelihood of decreased seed yield associated with spring grazing.

Black medic (Medicago lupulina L.) has become naturalized in south‐central USA where, in semiarid climates, it acts as a cool‐season annual. Cultivation for wildlife and livestock forage and seed has not been fully realized as cultivars adapted to warm and dry climates have not been developed. This study evaluated forage yields and nutritive value of black medic accessions collected in Texas. March, April, and May forage yield, acid detergent fiber (ADF), acid detergent lignin (ADL), N, and P concentrations of 11 black medic accessions collected in Texas were compared with cultivar George at Stephenville, TX, during establishment and first self‐reseeding years. Entries exhibited no frost damage and insignificant insect damage, but some Texas accessions were more vigorous in February and flowered earlier than other Texas accessions and George. Some Texas accessions were also more productive (P < 0.01) than others as well as George. Forage yields among entries ranged from 0.6 to 1.5 Mg ha−1 yr−1 when averaged over years and harvest months. Harvest month affected all entry yields equally and peaked at 2.3 Mg forage ha−1 yr−1 during May of the first season but declined in the second, self‐reseeding year despite greater rainfall. March ADF, ADL, N, and P concentrations tended to be lower than those of later harvests while the higher‐yielding accessions also tended to have greater ADF and ADL concentrations. The results indicate that forage yield and nutritive value of naturalized black medic germplasm from Texas is variable and that a blend from the southern Great Plains should be developed.

Cotton (Gossypium hirsutum L.) response to P fertilizer can vary within fields, making P recommendations difficult. Phosphorus response may be more predictable with variable‐rate fertilization, which matches soil test P and P fertilizer rate on a site‐specific basis. Our first objective was to determine the effect of landscape position and soil series on cotton P accumulation, lint yields, and P fertilizer response on two irrigated cotton sites in the Southern High Plains of Texas. The second objective was to compare variable‐rate P, blanket‐rate P, and zero P applications. Mehlich‐3 P levels ranged from 8 to 25 mg P kg−1 at Lamesa, and from 12 to 23 mg P kg−1 at Ropesville. Phosphorus fertilizer was not recommended when Mehlich‐3 P >33 mg P kg−1. In both years at Lamesa, P accumulation at early squaring and lint yields were greater in the bottomslope than in the south‐facing sideslope. Phosphorus fertilizer did not affect lint yields at Lamesa in 2000. In 2001, Lamesa lint yields responded to variable‐rate and blanket‐rate P in the south‐facing sideslope only, which had just 8 mg P kg−1. At Ropesville in 2000, early P accumulation, biomass and lint yields responded to P on a calcareous soil but not on a noncalcareous soil. In all cases, yields were similar between variable‐rate and blanket‐rate P. Thirty‐eight percent less P was applied with variable‐rate than blanket‐rate treatments in 3 of 4 site‐yr. However, more research is needed to determine if fertilizer savings are consistent enough to offset the greater costs of variable‐rate P fertilization.

The economically optimum N rate (EONR) required for corn (Zea mays L.) may vary spatially due to variation in soil characteristics and temporally due to the interactions of environmental factors. The objectives of this research were to quantify the impact of field variability on the yield response of corn to N fertilization and to evaluate the temporal stability of these response functions. A production field near Revere, MN, was cropped with corn in 1995, 1997, and 1999 in rotation with soybean [Glycine max (L.) Merr.]. Four replications of seven treatments were established in a split‐plot arrangement of a randomized complete block design. Main plots consisted of three N rates (0, 67, 134, and 202 kg ha−1) while the split plots were two rates (0 and 0.56 kg ha−1) of nitrapyrin [2‐chloro‐6 (trichloromethyl)‐pyridine]. Each replication was divided into subblocks to estimate spatial patterns in yield N response and EONR. Spatial analysis indicated that only half of the field responded to N. Uniform application recommendation of 145 kg N ha−1 for the whole field overfertilized these areas while other areas were underfertilized. Variable‐rate N applications according to the EONR would have resulted in 69 and 75 kg ha−1 less N being applied than the uniform N rate in 1997 and 1999, respectively. Potential economic benefits were $8 and $23 ha−1 higher than the uniform N rate in 1997 and 1999, respectively. Approximately 60% of the field responded in a similar manner in both 1997 and 1999, suggesting that temporal variations must also be considered with site‐specific N management.
