Nitrite and nitrate poisoning with special reference to ‘Grasslands Tama’ ryegrass (1974)

Abstract Extract The July 1973 issue of the New Zealand Journal of Agriculture discussed the Tama revolution. No mention was made of the possibility of nitrite poisoning in cattle grazing ‘Grasslands Tama’ (tetraploid westerwolds) ryegrass. There have been deaths from nitrite poisoning in cattle grazing Tama ryegrass and other crops in many districts this year, and this experience with a brief discussion on nitrite/nitrate poisoning is presented for the guidance of those who may be considering Tama ryegrass as a fodder crop.
On Learning the Past Tenses of English Verbs (1986)

Abstract : This paper presents an alternative to the standard rule based account of a child's acquisition of the past tense in English. Children are typically said to pass through a three-phase acquisition process in which they first learn past tense by rote, then learn the past tense rule and over regularize, and then finally learn the exceptions to the rule. We show that the acquisition data can be accounted for in more detail by dispensing with the assumption that the child learns rules and substituting in its place a simple homogeneous learning procedure. We show how rule-like behavior can emerge from the interactions among a network of units encoding the root form to past tense mapping. A large computer simulation of the learning process demonstrates the operating principles of our alternative account, shows how details of the acquisition process not captured by the rule account emerge, and makes predictions about other details of the acquisition process not yet observed. Keywords: Learning; networks; Language; Verbs; Perceptions; Morphology.

Effect of Shape and Parameters of Perforation in a Vertical Wellbore with Two Perforations (without Porous Media) on Pressure Drop (2017)

This paper present to predict the effect of diameter and length of perforation, inflow angle of perforation, inflow velocity and shape of perforation on pressure drop and then productivity index of vertical wellbore with two perforations. In this study, a Computational Fluid Dynamics (CFD) software code ANSYS CFX15.0 has been used to simulate a model of 3-D turbulent flow with stander k−∈ in a perforated vertical wellbore. The simulation for the vertical wellbore is performed by applying the laws of conservation of mass and momentum. The effect of perforation diameter and length of perforation, inflow angle, inflow types of inlet velocity to the perforation and inflow velocity for 180o and two perforations is studied. From the results of this study, the friction pressure drop is a major component of the total pressure drop and the maximum static (friction) pressure drop occurs at the location of perforation and increases with increasing the perforation diameter. For all the perforation diameter with constant length (0.15 m), the friction pressure drop is higher than 82% of the total pressure, the acceleration pressure drop is less than 16% of the pressure drop for both numerical and theoretical results. The mixing pressure drop is about 2% of the total pressure drop for the numerical results. The increase of inflow to main flow rate ratio increasing the total pressure drop and then decreasing in productivity index.

A Pragmatic Approach for Refined Feature Selection for the Prediction of Road Accident Severity (2014)

Road accident analysis is very challenging task and investigating the dependencies between the attributes become complex because of many environmental and road related factors. An exhaustive research is being conducted to identify the optimal factors which influence fatal accidents. In this paper we propose a novel methodology called Voting Algorithm for Aggregated Feature Selection (VAAFS) which selects an optimal number of significant features with majority votes identified by more than one Feature Mining algorithms. The optimal features selected by VAAFS will be then extended to the classifiers over an Indian road accident data set obtained from the Coimbatore City Traffic Head Quarters, Tamilnadu, India and with international datasets obtained from Fatality Analysis Reporting System (FARS), USA, and the STATS19 data collection system, maintained by the of United Kingdom (UK) to model the accident severity. The output from VAAFS shows that type of vehicle, high risk road users like pedestrian and two wheelers, young road users, government holidays, selected week days, manner of collision, seating position etc. are most significant factors in modeling Accident Severity. The proposed method is highly successful in reducing misclassification error rate and to improve the predictive accuracy with optimal features than the previous studies. It seems very promising for observing road accident patterns.

Early Detection of &lt;i&gt;Cercospora&lt;/i&gt; Species in Soybean Plants: Immunologic and Molecular Methods (2015)

Late-cycle diseases (LCD) cause a significant deterioration in quality and reduce yields in soybean crops. In Argentina, in particular, leaf blight and purple seed stain, caused by the agent Cercospora kikuchii, and frog eye spot, caused by C. sojina, are the prevailing sources of diseases. The early, rapid and accurate detection of these phytopathogens becomes essential, and would contribute to preserving both the environment and the health of humans and animals by preventing the wasteful or improper use of chemicals such as pesticides. In order to detect Cercospora species in soybean plants at an early stage, immunochemical and molecular techniques were developed in this work. Strains from the NITE Biological Resource Center collection (Japan): Cercospora kikuchii NBRC 6711 and Cercospora sojina NBRC 6715 and regional isolates of C. kikuchii were used. To develop Dot-Blot and PCR techniques, experiments with plants undergoing different treatments were carried out: those experimentally inoculated with these fungi, those treated with sterile water and healthy plants as well. Both techniques allowed the detection, at early stages, of Cercospora species involved in two of the most frequent LCD in the country, when the cercosporin concentration produced by the fungus was higher than 3.93 ± 0.39 nmol·cyl-1 ±SD. The sensitivity between both techniques was very different. While Dot-Blot allowed the detection of the disease 4 days after inoculation, PCR detected it after 4 hours, even without visible symptoms of the disease.
Nonlinear Aeroelastic Analysis of Joined-Wing Aircraft (2003)

Joined-wing aircraft are being designed for ‘sensorcraft’ configuration. Joined wings lead to multiple load paths and constraints. The focus of this work is to understand the nonlinear structural as well as aeroelastic behavior of joined wings. The paper presents a formulation for the nonlinear aeroelastic analysis of joined wings. Results are presented for two joined wings configurations. Overall, the joined wings are found to be stier than single wing configuration. The ‘non-planar’ joined wing is found to be stier than the ‘planar’ joined wing. The structural dynamic characteristics of the joined wings are also presented. The bending modes are similar to the cantilevered beam modes while the torsional vibrations are restricted to the unconstrained part of the main wing. The structural analysis showed negligible nonlinear eects for static deformation as well as for structural dynamics characteristics.

Real-Virtual World Device Synchronization in a Cloud-Enabled Social Virtual Reality IoT Network (2019)

Virtual reality (VR) is currently being used in many different areas such as car prototyping, gaming, medical training, teaching, and so on. The Internet of Things (IoT) devices such as systems-on-achip (e.g. Raspberry Pi), smart appliances, and sensors support a wide range of services, including machine automation, and remote monitoring and control. This paper introduces a novel social VR-IoT environment, which allows users to share and control local or remote IoT devices in a virtual platform. Two approaches using the VR-IoT solution are presented: one local network-based and one cloud-based. The proposed VR-IoT environment contains VRITESS, the novel VR-IoT Environment Synchronization Scheme, which facilitates a consistent and integrated experience for users by enabling control of real IoT objects with VR headsets. The control of some IoT objects in extreme environments or devices which are complex to operate can be simplified in a virtual environment. The VRITESS synchronization scheme maintains the real objects updated following instructions given in the virtual world and vice-versa. Testing involved local network-based and cloud-based testbeds created with a VR headset and IoT devices with the Performance Engineering Laboratory, Dublin City University's, Ireland. Test results demonstrated that lower latency is experienced in the local-network testbed in comparison with the cloud testbed. Furthermore, tests regarding the communications protocols implemented in the cloud testbed indicated that MQTT generates less delay and data traffic than REST.
MAP kinase does not inactivate, but rather prevents the cyclin degradation pathway from being turned on in <i>Xenopus</i> egg extracts (1996)

Unfertilized frog eggs arrest at the second meiotic metaphase, due to cytostatic activity of the c-mos proto-oncogene (CSF). MAP kinase has been proposed to mediate CSF activity in suppressing cyclin degradation. Using an in vitro assay to generate CSF activity, and recombinant CL 100 phosphatase to inactivate MAP kinase, we confirm that the c-mos proto-oncogene blocks cyclin degradation through MAP kinase activation. We further show that for MAP kinase to suppress cyclin degradation, it must be activated before cyclin B-cdc2 kinase has effectively promoted cyclin degradation. Thus MAP kinase does not inactivate, but rather prevents the cyclin degradation pathway from being turned on. Using a constitutively active mutant of Ca2+/calmodulin dependent protein kinase II, which mediates the effects of Ca2+ at fertilization, we further show that the kinase can activate cyclin degradation in the presence of both MPF and the c-mos proto-oncogene without inactivating MAP kinase.
People, poverty and the Earth Summit. (1992)

UNCED is about human beings managing their affairs so that all can achieve a reasonably good life without destroying the life-supporting environment. Currently human activities are approaching an upset of environmental balance through production of greenhouse gases, depletion of the ozone layer, and reduction of natural resources. Equity is the right to a decent life for the current human population of 5.5 billion and the future 10 billion expected within the next 50 years. A minimum use of environmental space/person is required. The Earth Summit will be a broad statement of environmental policy. Agenda 21 includes 115 action programs within 40 chapters. Separate conventions will be held on climate and biodiversity. The secretariat of UNCED has been working primarily with Agenda 21. Population issues are emphasized in Chapter 5 ("Demographic Dynamics and Sustainability") of the first section in Agenda 21 on Social and Economic Dimensions. The program areas include 1) research on the links between population, the environment, and development; 2) formulation by governments of integrated national policies on environment and development, which account for demographic trends, and promotion of population literacy; and 3) implementation of local level programs to ensure access to education and information and services in order to plan families freely and responsibly. Increases in funding for the population program are anticipated to be US $9 billion by the year 2000 and about US $7 billion/year until then. The year 2000 will bring with it a doubling of urban population in developing countries. There are challenges and opportunities to expand private sector job creation, education, clean water, and family health services. In addition to managing human settlements, there is also management of fragile ecosystems, which means relieving the pressure on these lands through urban migration or relocation to richer agricultural areas. The goal for agriculture is to triple food outputs over the next 50 years without increasing land use; improved soil and management systems are needed. Ocean/seas protection from pollution and provision of an adequate, clean water supply are other challenges. Demographic transition must be completed in order to improve global development success.
Auxiliary Beam Pair Enabled AoD and AoA Estimation in Closed-Loop Large-Scale mmWave MIMO Systems (2016)

Channel estimation is of critical importance in millimeter-wave (mmWave) multiple-input multiple-output (MIMO) systems. Due to the use of large antenna arrays, low-complexity mmWave specific channel estimation algorithms are required. In this paper, an auxiliary beam pair design is proposed to provide high-resolution estimates of the channel's angle-of-departure (AoD) and angle-of-arrival (AoA) for mmWave MIMO systems. By performing an amplitude comparison with respect to each auxiliary beam pair, a set of ratio measures that characterize the channel's AoD and AoA are obtained by the receiver. Either the best ratio measure or the estimated AoD is quantized and fed back to the transmitter via a feedback channel. The proposed technique can be incorporated into control channel design to minimize initial access delay. Though the design principles are derived assuming a high-power regime, evaluation under more realistic assumption shows that by employing the proposed method, good angle estimation performance is achieved under various signal-to-noise ratio levels and channel conditions.

Oxidative Stress, Mitochondrial Dysfunction, and Aging (2011)

Aging is an intricate phenomenon characterized by progressive decline in physiological functions and increase in mortality that is often accompanied by many pathological diseases. Although aging is almost universally conserved among all organisms, the underlying molecular mechanisms of aging remain largely elusive. Many theories of aging have been proposed, including the free-radical and mitochondrial theories of aging. Both theories speculate that cumulative damage to mitochondria and mitochondrial DNA (mtDNA) caused by reactive oxygen species (ROS) is one of the causes of aging. Oxidative damage affects replication and transcription of mtDNA and results in a decline in mitochondrial function which in turn leads to enhanced ROS production and further damage to mtDNA. In this paper, we will present the current understanding of the interplay between ROS and mitochondria and will discuss their potential impact on aging and age-related diseases.
Substrate binding and catalysis by ribonuclease P from cyanobacteria and <i>Escherichia coli</i> are affected differently by the 3′ terminal CCA in tRNA precursors (1999)

We have studied the effect of the 3' terminal CCA sequence in precursors of tRNAs on catalysis by the RNase P RNA or the holoenzyme from the cyanobacterium Synechocystis sp. PCC 6803 in a completely homologous system. We have found that the absence of the 3' terminal CCA is not detrimental to activity, which is in sharp contrast to what is known in other bacterial systems. We have found that this is also true in other cyanobacteria. This situation correlates with the anomalous structure of the J15/16 loop in cyanobacteria, which is an important loop in the CCA interaction in Escherichia coli RNase P, and with the fact that cyanobacteria do not code the CCA sequence in the genome but add it posttranscriptionally. Modification of nucleotides 330-332 in the J15/16 loop of Synechocystis RNase P RNA from GGU to CCA has a modest effect on kcat for CCA-containing substrates and has no effect on cleavage-site selection. We have developed a direct physical assay of the interaction between RNase P RNA and its substrate, which was immobilized on a filter, and we have determined that Synechocystis RNase P RNA binds with better affinity the substrate lacking CCA than the substrate containing it. Our results indicate a mode of substrate binding in RNase P from cyanobacteria that is different from binding in other eubacteria and in which the 3' terminal CCA is not involved.
A preprocessing method to increase high frequency response of a parametric loudspeaker (2013)

Unlike a conventional loudspeaker, a parametric loudspeaker whose principle is derived from nonlinear acoustic effects in air can create a controllable sound beam with a compact emitter. Therefore, the parametric loudspeaker is advantageous in deployments where personal audio zones are in demand. However, it is a dilemma that the sound generation principle of parametric loudspeaker leads to a narrow bandwidth of itself, which hinders its popularization in applications requiring high fidelity. In this paper, we propose a tentative treatment of harmonic distortions incurred in parametric loudspeakers, whereby the asymmetrical amplitude modulation (AAM) method is used to extend the high frequency response by doubling the higher cut-off frequency.
